®
) devices, part of a scalable 8-bit
PSoC 3 and 32-bit PSoC 5 platform. The CY8C53 family provides configurable blocks of analog, digital, and interconnect circuitry

PSoC’s digital subsystem provides half of its unique
configurability. It connects a digital signal from any peripheral to
any pin through the digital system interconnect (DSI). It also
provides functional flexibility through an array of small, fast,
low-power UDBs. PSoC Creator provides a library of pre-built
and tested standard digital peripherals (UART, SPI, LIN, PRS,
CRC, timer, counter, PWM, AND, OR, and so on) that are
mapped to the UDB array. The designer can also easily create a
digital circuit using boolean primitives by means of graphical
design entry. Each UDB contains programmable array logic
(PAL)/programmable logic device (PLD) functionality, together
with a small state machine engine to support a wide variety of
peripherals.

5: CY8C53 Family Datasheet
In addition to the flexibility of the UDB array, PSoC also provides
configurable digital blocks targeted at specific functions. For the
CY8C53 family these blocks can include four 16-bit timer,
counter, and PWM blocks; I
2
C slave, master, and multimaster
and Full-Speed USB.
For more details on the peripherals see the
“Example
Peripherals”
section on page 32 of this data sheet. For
information on UDBs, DSI, and other digital blocks, see the
“Digital Subsystem”
section on page 32 of this data sheet.
PSoC’s analog subsystem is the second half of its unique
configurability. All analog performance is based on a highly
accurate absolute voltage reference with less than 1% error over
temperature and voltage. The configurable analog subsystem
includes:
Analog muxes
Comparators
Analog mixers
Voltage references
Analog-to-Digital Converters (ADC)
Digital-to-Analog Converters (DACs)
PSoC’s CPU subsystem is built around a 32-bit three-stage
pipelined ARM Cortex-M3 processor running at up to 67 MHz.
The Cortex-M3 includes a tightly integrated nested vectored
interrupt controller (NVIC) and various debug and trace modules.
The overall CPU subsystem includes a DMA controller, cache,
and interrupt controller. The NVIC provides low latency, nested
interrupts, and tail-chaining of interrupts and other features to
increase the efficiency of interrupt handling. The DMA controller
enables peripherals to exchange data without CPU involvement.
This allows the CPU to run slower (saving power) or use those
CPU cycles to improve the performance of firmware algorithms.
The presence of cache improves the access speed of
instructions by the CPU.
PSoC’s nonvolatile subsystem consists of flash and
byte-writeable EEPROM. It provides up to 256 KB of on-chip
flash. The CPU can reprogram individual blocks of flash,
enabling boot loaders. A powerful and flexible protection model
secures the user's sensitive information, allowing selective
memory block locking for read and write protection. Two KB of
byte-writable EEPROM is available on-chip to store application
data.
The three types of PSoC I/O are extremely flexible. All I/Os have
many drive modes that are set at POR. PSoC also provides up
to four I/O voltage domains through the V
DDIO
pins. Every GPIO
has analog I/O, LCD drive, flexible interrupt generation, slew rate
control, and digital I/O capability. The SIOs on PSoC allow V
OH
to be set independently of V
DDIO
when used as outputs. When
SIOs are in input mode they are high impedance. This is true
even when the device is not powered or when the pin voltage
goes above the supply voltage. This makes the SIO ideally suited
for use on an I
2
C bus where the PSoC may not be powered when
other devices on the bus are. The SIO pins also have high
current sink capability for applications such as LED drives. The
programmable input threshold feature of the SIO can be used to
make the SIO function as a general purpose analog comparator.
For devices with Full-Speed USB the USB physical interface is
also provided (USBIO). When not using USB these pins may
also be used for limited digital functionality and device
programming. All the features of the PSoC I/Os are covered in
detail in the
“I/O System and Routing”
section on page 25 of this
data sheet.
The PSoC device incorporates flexible internal clock generators,
designed for high stability and factory trimmed for high accuracy.
The internal main oscillator (IMO) is the master clock base for
the system, and has 5% accuracy at 3 MHz. The IMO can be
configured to run from 3 MHz up to 48 MHz. Multiple clock
derivatives can be generated from the main clock frequency to
meet application needs. The device provides a PLL to generate
system clock frequencies up to 67 MHz from the IMO, external
crystal, or external reference clock. It also contains a separate,
very low-power internal low speed oscillator (ILO) for the sleep
and watchdog timers. A 32.768 kHz external watch crystal is also
supported for use in real time clock (RTC) applications. The
clocks, together with programmable clock dividers, provide the
flexibility to integrate most timing requirements.
All GPIO pins can route analog signals into and out of the device
using the internal analog bus. This allows the device to interface
up to 62 discrete analog signals.
The CY8C53 family also offers a SAR ADC. Featuring 12-bit
conversions at up to 700 k samples per second, it also offers low
nonlinearity and offset errors. It is well suited for a variety of
higher speed analog applications.
Two high speed voltage or current DACs support 8-bit output
signals at an update rate of up to 5.5 Msps. They can be routed
out of any GPIO pin. You can create higher resolution voltage
DAC outputs using the UDB array. This can be used to create a
pulse width modulated (PWM) DAC of up to 10 bits, at up to
48 kHz. The digital DACs in each UDB support PWM, PRS, or
delta-sigma algorithms with programmable widths.
In addition to the ADC and DACs, the analog subsystem
provides multiple:
Comparators
Uncommitted opamps
Configurable switched capacitor/continuous time (SC/CT)
blocks. These support:
Transimpedance amplifiers
Programmable gain amplifiers
Mixers
Other similar analog components
See the
“Analog Subsystem”
section on page 44 of this data
sheet for more details.

5: CY8C53 Family Datasheet
The CY8C53 family supports a wide supply operating range from
2.7 to 5.5 V. This allows operation from regulated supplies such
as 3.3 V ± 10% or 5.0 V ± 10%, or directly from a wide range of
battery types.
PSoC supports a wide range of low power modes. These include
a 300-nA hibernate mode with RAM retention and a 2-µA sleep
mode.
Power to all major functional blocks, including the programmable
digital and analog peripherals, can be controlled independently
by firmware. This allows low-power background processing
when some peripherals are not in use. This, in turn, provides a
total device current of only 6 mA when the CPU is running at
6 MHz.
The details of the PSoC power modes are covered in the
“Power
System”
section on page 22 of this data sheet.
PSoC uses a SWD interface for programming, debug, and test.
Using this standard interface enables the designer to debug or
program the PSoC with a variety of hardware solutions from
Cypress or third party vendors. The Cortex-M3 debug and trace
modules include FPB, DWT, and ITM. These modules have
many features to help solve difficult debug and trace problems.
Details of the programming, test, and debugging interfaces are
discussed in the
“Programming, Debug Interfaces, Resources”
section on page 53 of this data sheet.
2. Pinouts
The VDDIO pin that supplies a particular set of pins is indicated
by the black lines drawn on the pinout diagrams in
Figure 2-1
and
Figure 2-2.
Using the VDDIO pins, a single PSoC can support
multiple interface voltage levels, eliminating the need for off-chip
level shifters. Each VDDIO may sink up to 20 mA total to its
associated I/O pins and opamps, and each set of VDDIO
associated pins may sink up to 100 mA.
