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 85C 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.

PRELIMINARY CM2400-05
Functional Description
The CM2400-05 USB Transceiver supports 3 different power supply configurations, which can be configured dynamically. Table 1 details the various configurations. In Normal Mode the internal regulator produces 3.3V from VBUS to power the internal drivers and receivers associated with the USB protocol.
VBUS Connected Connected Not Connected VCC Connected Not Connected Connected CONFIGURATION Normal Mode Disable Mode Sharing Mode PIN VBUS VREG VCC VPU D+, DVP/VPO, VM/VMO RCV USB_DET Inputs Sharing Mode State VBUS < 3.6V Pulled Down Present High-Z (off) High-Z H L L High-Z Disable Mode State 4.1V to 5.5V 3.3V Out Not Present High-Z (off) High-Z Invalid Invalid Invalid High-Z
Table 1: Power Supply Connections In Disable and Sharing Mode, all input/output pins follow the states defined in Table 2. In Sharing mode, D+, D- and VPU can have voltages higher then VCC. This allows other external signals to share D+ and D- while USB signaling is disabled.
Table 2: Pin States in Disable or Sharing Mode Table 3 lists the functions of the modes associated with suspend and OE pins. When Suspend is low and OE is high, signal levels on D+ and D- are determined by other USB devices and pull-up/down resistors. In Suspend Mode (SPND = HIGH) the differential receiver is inactive and output RCV is always LOW. Out of suspend signaling is detected via the single-ended receivers VP and VM. During suspend and while the output is still enabled (OE = LOW), D+ and D- lines are driven to their intended states. This is permitted because driving during suspend is used to signal remote wake-up by driving a 'K' signal for a period of 1 to 15ms.

Functional Description (cont'd)
Detailed in Table 4 is the differential result for all variations on VP/VPO and VM/VMO.
VP/VPO L L H H VM/VMO L H L H
Result Logic `0' SE0 Logic `1' SE0
Detection of a VBUS voltage is accomplished via an internal Comparator with hysteresis. The output from this Comparator is fed via the level translator to ensure compatibility with processor core voltages and output to pin USB_DET. When VBUS is over 4.1 volts USB_DET is HIGH. When VBUS is under 3.6 volts USB_DET is LOW.
Table 4: Operating Mode (OE = L) Table 5 details the receiving function when OE is HIGH (driver disabled). RCV denotes the signal level on the output RCV just before an SE0 state occurs. This level is stable during the SE0 period.
VP L H L VM H L L
The CM2400-05 USB transceiver includes an enumeration pin (ENUM) which internally connects VPU to VREG when enabled. This allows a processor running at a core voltage different than 3.3V to switch the pullup resistor in and out without the need for external circuitry.
