It supports a speed of 12Mbits/s (Full Speed Mode). An internal level shifter allows interface to Application Specific ICs (ASICs) and Programmable Logic Devices (PLD's) running at core voltages of 1.65V to 3.6V. The CM2400-02/03/04 features an internal 5V to 3.3V regulator which is used to power the USB transceiver via the USB supply VBUS. The CM2400-04 features a Mode Input pin (MODE) which allows the device to operate in either single or differential input mode. This device is ideal for portable electronic devices such as mobile phones, digital still cameras, PDAs (Personal Digital Assistants) and IAs (Information Appliances). The CM2400-02/03/04 is packaged in a small form-factor 16-lead HBCC or TSSOP package to conserve board space.

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 stable during an SE0 condition. Single-ended D+ receiver output for detection of a single-ended zero or error conditions Single-ended D- receiver output for detection of a single-ended zero or error conditions. Suspend input. Allows the device to enter a low power state while the USB is inactive. Mode input (CM2400-04). Selects between differential (VPO, VMO) and singleended mode (VO, FSEO). Ground input (CM2400-02/03). Supply voltage for digital I/O pins. Voltages supported: 1.65 to 3.6V. Speed Input. If SPEED is logic '1', selects full speed. If SPEED is logic '0', selects low speed. SPEED changes slope rise and fall time on D+ and D-. Negative USB data connection. Positive USB data connection. In full-speed connect mode, connect to VPU via a 1.5kΩ resistor. Tolerance of this resistor is defined in the USB specification REV 1.1 & 2.0 Driver data input. Driver data input. Regulated supply voltage output during USB operation of VBUS. 1µF decoupling capacitor is required. Supply voltage input. Can be directly connected to USB VBUS. Pull-up supply voltage. Pin function is controlled by input ENUM. 11 12 13 14 15 13 14 15 16 1 VPO/VO VMO/FSEO VREG VBUS VPU © 2004 California Micro Devices Corp. All rights reserved. 2 430 N.
