Product Description
The CM2400-05 Universal Serial Bus (USB) trans-
ceiver is fully compliant with USB specification, revi-
sions 1.1 and 2.0. It supports a speed of 12Mbits/s
(Full Speed Mode).
An internal level shifter allows interface to Application
Specific Integrated Circuits (ASICs) and Programma-
ble Logic Devices (PLDs) running at core voltages of
1.65V to 3.6V.
An internal 5V to 3.3V regulator is used to power the
CM2400-05 USB transceiver via the USB supply V
BUS
.

are bi-directional interface pins. In
one mode they function as the differential driver input
data. In another mode they function as the output of
the single ended receivers. This mode is configured by
the OE pin.
This device is ideal for portable electronic devices such
as mobile phones, digital still cameras, PDAs (Personal
Digital Assistants) and IAs (Information Appliances).
The CM2400-05 is manufactured in small form-factor
16-lead HBCC or TQFN packages to conserve board
space and is available with optional lead-free finishing.

DESCRIPTION
Input for Output Enable (Active low). Enables transceiver driver to transmit data on the USB bus. When
OE pin = LOW, driver circuitry is enabled.
Differential receiver output of D+ and D- input data lines. The output state of RCV is preserved and sta-
ble during an SE0 condition.
Bi-directional input output of D+. Configured by OE.
Bi-directional input output of D-. Configured by OE.
Suspend input. Allows the device to enter a low power state while the USB is inactive.
No internal connection to circuitry.
Supply voltage for digital I/O pins. Voltages supported: 1.65 to 3.3V.
I/O level USB detect output. Logic High indicates that a USB cable is present.
Negative USB data connection.
Positive USB data connection. In full-speed connect mode, connect to V
PU
via a 1.5kΩ resistor. Toler-
ance of this resistor is defined in the USB specification REV 1.1 & 2.0
No internal connection to circuitry.
No internal connection to circuitry.
Regulated supply voltage output during USB operation of V
BUS
. 1µF decoupling capacitor is required.
Supply voltage input. Can be directly connected to USB V
BUS
.
Pull-up supply voltage. Pin function is controlled by input ENUM.
Enumerate, allows software to control connection of the external pull-up via the level translator. If
ENUM = LOW then V
PU
is floating. If ENUM = HIGH then V
PU
is internally connected to V
REG
.
The ground terminal is connected to the exposed diepad (heatsink)
