www.DataSheet4U.com PRELIMINARY CM2400-05 Universal Serial Bus Transceiver with Level Translator Features • • • • • • • • • • • • Complies with USB Specification Rev 1.1 & 2.0 Supports Full Speed Mode (12Mbit/s) Integrated 5V to 3.3V regulator Bi-directional driver input/output pins Two single-ended receivers with hysteresis USB detection of VBUS via level translator Stable RCV output during SE0 condition Low power operation Supports 1.65 to 3.6V I/O voltage levels Full industrial operating range -40 to 85°C Available in tiny HBCC-16 and TQFN-16 packages Lead-free versions available Product Description The CM2400-05 Universal Serial Bus (USB) transceiver is fully compliant with USB specification, revisions 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 Programmable 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 VBUS. VM/VMO and VP/VPO 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.

VREG VBUS VPU ENUM GND 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 stable 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 VPU via a 1.5kΩ resistor. Tolerance 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 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. Enumerate, allows software to control connection of the external pull-up via the level translator. If ENUM = LOW then VPU is floating. If ENUM = HIGH then VPU is internally connected to VREG. The ground terminal is connected to the exposed diepad (heatsink) © 2004 California Micro Devices Corp. All rights reserved. 2 430 N.
