WT11i uses a monopole type on a chip antenna with maximum gain of 0.5 dBi. The radiation pattern and the
total radiated efficiency are dependent on the layout and any metal around the antenna has an effect on the
radiation characteristics. Typically the efficiency is 30 ... 50%.

5 Layout Guidelines

WT11i is pin compatible with WT11 despite of slightly different external dimensions. For new design it
recommended to follow the land pattern shown in the figure below.

                                           Figure 15: Recommended PCB land pattern for WT11i

Do not place any copper under the antenna. The minimum recommended keep out area is shown in the figure
16. Any dielectric material in close proximity to the antenna will effect on the impedance matching of the
antenna by lowering the resonance frequency. Figure 17 shows how different FR4 thickness under the
antenna effect on the resonance frequency. Recommended PCB thickness for the PCB is 1.6 mm 2.8 mm.
Avoid placing plastic cover closer than 3 mm from the antenna as this will also tune the resonance frequency
downwards.

Use good layout practices to avoid excessive noise coupling to supply voltage traces or sensitive analog
signal traces, such as analog audio signals. If using overlapping ground planes use stitching vias separated
by max 3 mm to avoid emission from the edges of the PCB. Connect all the GND pins directly to a solid GND
plane and make sure that there is a low impedance path for the return current following the signal and supply
traces all the way from start to the end.

6 UART Interface

This is a standard UART interface for communicating with other serial devices.WT11i UART interface provides
a simple mechanism for communicating with other serial devices using the RS232 protocol.
Four signals are used to implement the UART function. When WT11i is connected to another digital device,
UART_RX and UART_TX transfer data between the two devices. The remaining two signals, UART_CTS and
UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. All
UART connections are implemented using CMOS technology and have signalling levels of 0V and VDD.
UART configuration parameters, such as data rate and packet format, are set using WT11i software.

Note:
In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated serial
port adapter card is required for the PC.

                                                         Table 11: Possible UART Settings

The UART interface is capable of resetting WT11i upon reception of a break signal. A break is identified by a
continuous logic low (0V) on the UART_RX terminal, as shown in Figure 9. If tBRK is longer than the value,
defined by PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur. This feature allows a
host to initialise the system to a known state. Also, WT11i can emit a break character that may be used to
wake the host.

                                                                 Figure 20: Break Signal

Table 11 shows a list of commonly used data rates and their associated values for
PSKEY_UART_BAUD_RATE (0x204). There is no requirement to use these standard values. Any data rate
within the supported range can be set in the PS Key according to the formula in Equation 1

6.1 UART Bypass

                                                       Figure 21: UART Bypass Architecture

6.2 UART Configuration While Reset is Active

The UART interface for WT11i while the chip is being held in reset is tristate. This will allow the user to daisy
chain devices onto the physical UART bus. The constraint on this method is that any devices connected to
this bus must tristate when WT11i reset is de-asserted and the firmware begins to run.

6.3 UART Bypass Mode

Alternatively, for devices that do not tristate the UART bus, the UART bypass mode on BlueCore4-External
can be used. The default state of BlueCore4-External after reset is de-asserted; this is for the host UART bus
to be connected to the BlueCore4-External UART, thereby allowing communication to BlueCore4-External via
the UART. All UART bypass mode connections are implemented using CMOS technology and have signalling
levels of 0V and VDD.
In order to apply the UART bypass mode, a BCCMD command will be issued to BlueCore4-External. Upon
this issue, it will switch the bypass to PIO[7:4] as Figure 21 indicates. Once the bypass mode has been
invoked, WT11i will enter the Deep Sleep state indefinitely.
In order to re-establish communication with WT11i, the chip must be reset so that the default configuration
takes effect.
It is important for the host to ensure a clean Bluetooth disconnection of any active links before the bypass
mode is invoked. Therefore, it is not possible to have active Bluetooth links while operating the bypass mode.
The current consumption for a device in UART bypass mode is equal to the values quoted for a device in
standby mode.

7 USB Interface

This is a full speed (12Mbits/s) USB interface for communicating with other compatible digital devices. WT11i
acts as a USB peripheral, responding to requests from a master host controller such as a PC.

The USB interface is capable of driving a USB cable directly. No external USB transceiver is required. The
device operates as a USB peripheral, responding to requests from a master host controller such as a PC.
Both the OHCI and the UHCI standards are supported. The set of USB endpoints implemented can behave as
specified in the USB section of the Bluetooth v2.1 + EDR specification or alternatively can appear as a set of
endpoints appropriate to USB audio devices such as speakers.

As USB is a master/slave oriented system (in common with other USB peripherals), WT11i only supports USB
Slave operation.

7.1 USB Data Connections

The USB data lines emerge as pins USB_DP and USB_DN. These terminals are connected to the internal
USB I/O buffers of the BlueCore4-External, therefore, have a low output impedance. To match the connection
to the characteristic impedance of the USB cable, resistors must be placed in series with USB_DP/USB_DN
and the cable.

7.2 USB Pull-Up resistor

WT11i features an internal USB pull-up resistor. This pulls the USB_DP pin weakly high when WT11i is ready
to enumerate. It signals to the PC that it is a full speed (12Mbits/s) USB device.

The USB internal pull-up is implemented as a current source, and is compliant with section 7.1.5 of the USB
specification v1.2. The internal pull-up pulls USB_DP high to at least 2.8V when loaded with a 15k 5% pull-
down resistor (in the hub/host) when VDD_PADS = 3.1V. This presents a Thevenin resistance to the host of
at least 900. Alternatively, an external 1.5k pull-up resistor can be placed between a PIO line and D+ on the
USB cable. The firmware must be alerted to which mode is used by setting PSKEY_USB_PIO_PULLUP
appropriately. The default setting uses the internal pull-up resistor.

7.3 USB Power Supply

The USB specification dictates that the minimum output high voltage for USB data lines is 2.8V. To safely
meet the USB specification, the voltage on the VDD supply terminal must be an absolute minimum of 3.1V.
Bluegiga recommends 3.3V for optimal USB signal quality.

7.4 Self-Powered Mode

In self-powered mode, the circuit is powered from its own power supply and not from the VBUS (5V) line of the
USB cable. It draws only a small leakage current (below 0.5mA) from VBUS on the USB cable. This is the
easier mode for which to design, as the design is not limited by the power that can be drawn from the USB
hub or root port. However, it requires that VBUS be connected to WT11i via a resistor network (Rvb1 and
Rvb2), so WT11i can detect when VBUS is powered up. BlueCore4-External will not pull USB_DP high when
VBUS is off.

Self-powered USB designs (powered from a battery or PSU) must ensure that a PIO line is allocated for USB
pullup purposes. A 1.5k 5% pull-up resistor between USB_DP and the selected PIO line should be fitted to the
design. Failure to fit this resistor may result in the design failing to be USB compliant in self-powered mode.
The internal pull-up in BlueCore is only suitable for bus-powered USB devices, e.g., dongles.

                                            Figure 22: USB Connections for Self-Powered Mode

The terminal marked USB_ON can be any free PIO pin. The PIO pin selected must be registered by setting
PSKEY_USB_PIO_VBUS to the corresponding pin number.

                                                  Figure 23: USB Interface Component Values

**) WT11i has internal 22 ohm series resistors at the USB lines.

7.5 Bus-Powered Mode

In bus-powered mode, the application circuit draws its current from the 5V VBUS supply on the USB cable.
WT11i negotiates with the PC during the USB enumeration stage about how much current it is allowed to
consume. On power-up the device must not draw more than 100 mA but after being configured it can draw up
to 500 mA.

For WT11i, the USB power descriptor should be altered to reflect the amount of power required. This is
accomplished by setting PSKEY_USB_MAX_POWER (0x2c6). This is higher than for a Class 2 application
due to the extra current drawn by the Transmit RF PA. By default for WT11i the setting is 300 mA.

When selecting a regulator, be aware that VBUS may go as low as 4.4V. The inrush current (when charging
reservoir and supply decoupling capacitors) is limited by the USB specification. See the USB Specification.
Some applications may require soft start circuitry to limit inrush current if more than 10uF is present between
VBUS and GND. The 5V VBUS line emerging from a PC is often electrically noisy. As well as regulation down
to 3.3V and 1.8V, applications should include careful filtering of the 5V line to attenuate noise that is above the
voltage regulator bandwidth. Excessive noise on WT11i supply pins will result in reduced receiver sensitivity
and a distorted RF transmit signal.

                                            Figure 24: USB Connections for Bus-Powered Mode

7.6 USB Suspend Current

All USB devices must permit the USB controller to place them in a USB suspend mode. While in USB
Suspend, bus-powered devices must not draw more than 2.5mA from USB VBUS (self-powered devices may
draw more than 2.5mA from their own supply). This current draw requirement prevents operation of the radio
by bus-powered devices during USB Suspend.

When computing suspend current, the current from VBUS through the bus pull-up and pull-down resistors
must be included. The pull-up resistor at the device is 1.5 k. (nominal). The pull-down resistor at the hub is
14.25k. to 24.80k. The pull-up voltage is nominally 3.3V, which means that holding one of the signal lines high
takes approximately 200uA, leaving only 2.3mA available from a 2.5mA budget. Ensure that external LEDs
and/or amplifiers can be turned off by BlueCore4-External. The entire circuit must be able to enter the
suspend mode.

7.7 USB Detach and Wake-Up Signaling

WT11i can provide out-of-band signaling to a host controller by using the control lines called USB_DETACH
and USB_WAKE_UP. These are outside the USB specification (no wires exist for them inside the USB cable),
but can be useful when embedding WT11i into a circuit where no external USB is visible to the user. Both
control lines are shared with PIO pins and can be assigned to any PIO pin by setting
PSKEY_USB_PIO_DETACH and PSKEY_USB_PIO_WAKEUP to the selected PIO number.

USB_DETACH is an input which, when asserted high, causes WT11i to put USB_DN and USB_DP in high
impedance state and turns off the pull-up resistor on DP. This detaches the device from the bus and is
logically equivalent to unplugging the device. When USB_DETACH is taken low, WT11i will connect back to
USB and await enumeration by the USB host.

USB_WAKE_UP is an active high output (used only when USB_DETACH is active) to wake up the host and
allow USB communication to recommence. It replaces the function of the software USB WAKE_UP message
(which runs over the USB cable) and cannot be sent while BlueCore4-External is effectively disconnected
from the bus.

7.8 USB Driver

A USB Bluetooth device driver is required to provide a software interface between BlueCore4-External and
Bluetooth software running on the host computer. Please, contact support@bluegiga.com for suitable drivers.

7.9 USB v2.0 Compliance and Compatibility

Although WT11i meets the USB specification, CSR cannot guarantee that an application circuit designed
around the module is USB compliant. The choice of application circuit, component choice and PCB layout all
affect USB signal quality and electrical characteristics. The information in this document is intended as a guide
and should be read in association with the USB specification, with particular attention being given to Chapter
7. Independent USB qualification must be sought before an application is deemed USB compliant and can
bear the USB logo. Such qualification can be obtained from a USB plugfest or from an independent USB test
house.
Terminals USB_DP and USB_DN adhere to the USB Specification v2.0 (Chapter 7) electrical requirements.
BlueCore4-External is compatible with USB v2.0 host controllers; under these circumstances the two ends
agree the mutually acceptable rate of 12Mbits/s according to the USB v2.0 specification.

8 Serial Peripheral Interface (SPI)

The SPI port can be used for system debugging. It can also be used for programming the Flash memory and
setting the PSKEY configurations. WT11i uses 16-bit data and 16-bit address serial peripheral interface, where
transactions may occur when the internal processor is running or is stopped. SPI interface is connected using
the MOSI, MISO, CSB and CLK pins.

SPI interface cannot be used for application purposes.

9 PCM Codec Interface

PCM is a standard method used to digitize audio (particularly voice) for transmission over digital
communication channels. Through its PCM interface, WT11i has hardware support for continual transmission
and reception of PCM data, thus reducing processor overhead for wireless headset applications. WT11i offers
a bidirectional digital audio interface that routes directly into the baseband layer of the on-chip firmware. It
does not pass through the HCI protocol layer.
Hardware on WT11i allows the data to be sent to and received from a SCO connection. Up to three SCO
connections can be supported by the PCM interface at any one time.
WT11i can operate as the PCM interface master generating an output clock of 128, 256 or 512kHz. When
configured as PCM interface slave, it can operate with an input clock up to 2048kHz. WT11i is compatible with
a variety of clock formats, including Long Frame Sync, Short Frame Sync and GCI timing environments.
It supports 13-bit or 16-bit linear, 8-bit -law or A-law companded sample formats at 8ksamples/s and can
receive and transmit on any selection of three of the first four slots following PCM_SYNC. The PCM
configuration options are enabled by setting PSKEY_PCM_CONFIG32.
WT11i interfaces directly to PCM audio devices.

NOTE: Analog audio lines are very sensitive to RF disturbance. Use good layout practices to ensure noise
less audio. Make sure that the return path for the audio signals follows the forward current all the way as close
as possible and use fully differential signals when possible. Do not compromise audio routing.

9.1 PCM Interface Master/Slave

When configured as the master of the PCM interface, WT11i generates PCM_CLK and PCM_SYNC.

                                                           Figure 26: PCM Interface Master
When configured as the Slave of the PCM interface, WT11i accepts PCM_CLK rates up to 2048kHz.

                                                           Figure 27: PCM Interface Slave

9.2 Long Frame Sync

Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or
samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When
WT11i is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8-bits long.
When WT11i is configured as PCM Slave, PCM_SYNC may be from two consecutive falling edges of
PCM_CLK to half the PCM_SYNC rate, i.e., 62.5s long.

                                 Figure 28: Long Frame Sync (Shown with 8-bit Companded Sample)

WT11i samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge.
PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or
on the rising edge.

9.3 Short Frame Sync

In Short Frame Sync, the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is
always one clock cycle long.

Bluegiga Technologies Oy

                          Page 33 of 46
                                         Figure 29: Short Frame Sync (Shown with 16-bit Sample)

As with Long Frame Sync, WT11i samples PCM_IN on the falling edge of PCM_CLK and transmits
PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of
PCM_CLK in the LSB position or on the rising edge.

9.4 Multi-slot Operation

More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO
connections can be carried over any of the first four slots.

                          Figure 30: Multi-slot Operation with Two Slots and 8-bit Companded Samples

9.5 GCI Interface

WT11i is compatible with the GCI, a standard synchronous 2B+D ISDN timing interface. The two 64kbits/s B
channels can be accessed when this mode is configured.

Bluegiga Technologies Oy

                          Page 34 of 46
                                                                Figure 31: GCI Interface

The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8kHz. With WT11i in Slave mode,
the frequency of PCM_CLK can be up to 4.096MHz.

9.6 Slots and Sample Formats

WT11i can receive and transmit on any selection of the first four slots following each sync pulse. Slot
durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used with 8-bit sample
formats. Durations of 16 clocks may be used with 8-bit, 13-bit or 16-bit sample formats.
WT11i supports 13-bit linear, 16-bit linear and 8-bit -law or A-law sample formats. The sample rate is
8ksamples/s. The bit order may be little or big endian. When 16-bit slots are used, the 3 or 8 unused bits in
each slot may be filled with sign extension, padded with zeros or a programmable 3-bit audio attenuation
compatible with some Motorola codecs.

9.7 Additional Features

WT11i has a mute facility that forces PCM_OUT to be 0. In master mode, PCM_SYNC may also be forced to
0 while keeping PCM_CLK running which some codecs use to control power down.

9.8 PCM_CLK and PCM_SYNC Generation

WT11i has two methods of generating PCM_CLK and PCM_SYNC in master mode. The first is generating
these signals by DDS from BlueCore4-External internal 4MHz clock. Using this mode limits PCM_CLK to 128,
256 or 512kHz and PCM_SYNC to 8kHz. The second is generating PCM_CLK and PCM_SYNC by DDS from
an internal 48MHz clock (which allows a greater range of frequencies to be generated with low jitter but
consumes more power). This second method is selected by setting bit 48M_PCM_CLK_GEN_EN in
PSKEY_PCM_CONFIG32. When in this mode and with long frame sync, the length of PCM_SYNC can be
either 8 or 16 cycles of PCM_CLK, determined by LONG_LENGTH_SYNC_EN in PSKEY_PCM_CONFIG32.
The Equation XXX describes PCM_CLK frequency when being generated using the internal 48MHz clock:

                          Page 36 of 46
                 Equation 2: PCM_CLK Frequency When Being Generated Using the Internal 48MHz Clock

The frequency of PCM_SYNC relative to PCM_CLK can be set using Equation XXX:

                                         Equation 3: PCM_SYNC Frequency Relative to PCM_CLK

CNT_RATE, CNT_LIMIT and SYNC_LIMIT are set using PSKEY_PCM_LOW_JITTER_CONFIG. As an
example, to generate PCM_CLK at 512kHz with PCM_SYNC at 8kHz, set
PSKEY_PCM_LOW_JITTER_CONFIG to 0x08080177.

9.9 PCM Configuration

The PCM configuration is set using two PS Keys, PSKEY_PCM_CONFIG32 detailed in Table 12 and
PSKEY_PCM_LOW_JITTER_CONFIG in Table 13. The default for PSKEY_PCM_CONFIG32 is 0x00800000,
i.e., first slot following sync is active, 13-bit linear voice format, long frame sync and interface master
generating 256kHz PCM_CLK from 4MHz internal clock with no tri-state of PCM_OUT.

10 I/O Parallel Ports

Six lines of programmable bidirectional input/outputs (I/O) are provided. All the PIO lines are power from VDD.

PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs. All PIO
lines are configured as inputs with weak pull-downs at reset. Any of the PIO lines can be configured as
interrupt request lines or as wake-up lines from sleep modes.

WT11i has a general purpose analogue interface pin AIO[1]. This is used to access internal circuitry and
control signals. It may be configured to provide additional functionality.

Auxiliary functions available via AIO[1] include an 8-bit ADC and an 8-bit DAC. Typically the ADC is used for
battery voltage measurement. Signals selectable at this pin include the band gap reference voltage and a
variety of clock signals: 48, 24, 16, 8MHz and the XTAL clock frequency. When used with analogue signals,
the voltage range is constrained by the analogue supply voltage internally to the module (1.8V). When
configured to drive out digital level signals (e.g., clocks), the output voltage level is determined by VDD.

10.1 PIO Defaults

Bluegiga cannot guarantee that these terminal functions remain the same. Refer to the software release note
for the implementation of these PIO lines, as they are firmware build-specific.

Bluegiga Technologies Oy

                          Page 39 of 46
11 Reset

WT11i may be reset from several sources: RESET pin, power on reset, a UART break character or via
software configured watchdog timer. The RESET pin is an active high reset and is internally filtered using the
internal low frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB
being active. It is recommended that RESET be applied for a period greater than 5ms.

The power on reset occurs when the VDD_CORE supply internally to the module falls below typically 1.5V
and is released when VDD_CORE rises above typically 1.6V. At reset the digital I/O pins are set to inputs for
bidirectional pins and outputs are tri-state.

WT11i has an internal power on reset circuit which holds the module in reset until all the supply voltages have
stabilized. The reset pin must be either floating or connected to high impedance during power on in order for
the power on reset circuit to work properly. If the reset pin is not connected to high impedance during power
on, then one must ensure that the reset is kept active until all the supply voltages have stabilized to prevent
the flash memory getting corrupted.

12.2 FCC and IC

For FCC, if the TX power of a Bluetooth module is higher than 13.9 dBm and the end product is used closer
than 20 cm from a human body, RF exposure has to be evaluated in the end product. For IC there is a similar
requirement except the power limit is 12 dBm. This might require either an own FCC ID for the end product, or
Class 2 Permissive Change to the grant of WT11i. WT11i is certified with both 12 dBm (FCC ID:
QOQWT11IA) and 17 dBm (FCC ID: QOQWT11I) TX power. When using QOQWT11IA, RF exposure
evaluation is not needed, but the TX power must be limited to 12 dBm.

WT11i complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

        (1) this device may not cause harmful interference, and

        (2) this device must accept any interference received, including interference that may
        cause undesired operation.

FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End
users must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter
must not be co-located or operating in conjunction with any other antenna or transmitter, except in accordance
with FCC test procedures. This transmitter is considered as mobile device. If TX power is set to 17 dBm, class
2 permissive change is required to allow portable use in a known host. Please contact support@bluegiga.com
for detailed information.

IC Statements:

This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the
following two conditions: (1) this device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation of the device.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically
radiated power (e.i.r.p.) is not more than that necessary for successful communication.

OEM Responsibilities to comply with FCC and Industry Canada Regulations

The WT11i-A module has been certified for integration into products only by OEM integrators under the
following conditions:

      The antenna(s) must be installed such that a minimum separation distance of 20cm is maintained
          between the radiator (antenna) and all persons at all times.

      The transmitter module must not be co-located or operating in conjunction with any other antenna or
          transmitter.

As long as the two conditions above are met, further transmitter testing will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance requirements
required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).

IMPORTANT NOTE: In the event that these conditions can not be met (for certain configurations or co-
location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered
valid and the FCC ID and IC Certification Number can not be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the
transmitter) and obtaining a separate FCC and Industry Canada authorization.

End Product Labeling

The WT11i-A Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC
Certification Number are not visible when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed module. In that
case, the final end product must be labeled in a visible area with the following:

                   "Contains Transmitter Module FCC ID: QOQWT11IA"

                   "Contains Transmitter Module IC: 5123A-BGTWT11IA"

or

                   "Contains FCC ID: QOQWT11IA

                   "Contains IC: 5123A-BGTWT11IA"

The OEM of the WT11i-A module must only use the approved antenna.

The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module or change RF related parameters in the user manual of the end product.

To comply with FCC and Industry Canada RF radiation exposure limits for general population, the
antenna(s) used for this transmitter must be installed such that a minimum separation distance of
20cm is maintained between the radiator (antenna) and all persons at all times and must not be co-
located or operating in conjunction with any other antenna or transmitter.
