Product Description
The CM240001HB Universal Serial Bus (USB) transceiver is fully compliant with the USB specification Rev 1.1 and 2.0. It supports a speed of 12Mbits/s (Full Speed). An internal level shifter allows interface to Application specific IC's (ASIC's) and Programmable logic devices (PLD's) running at core voltages of 1.65 to 3.3V. An internal 5-3.3V regulator is used to power the CM240001HB USB transceiver via the USB supply VBUS. Single and differential input modes are selectable by a mode input pin. This device is ideal for portable electronic devices such as mobile phones, digital still cameras, PDA (Personal Digital Assistants) and IR (Information Appliances).

Pin Functions 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. 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. Selects between differential (VPO, VMO) and single-ended mode (VO, FSEO). 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. Full speed connect mode, connect VPU via a 1.5k 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. 1uF 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).
Functional Description:
The CM240001HB 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. In Disable and Sharing Mode, all input/output pins follow the states defined in Table 2. 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. Detailed in Table 4.1 and 4.2 are the operating modes selected when MODE is set to HIGH and LOW. When MODE = HIGH, the differential input data interface mode is selected. The 2 driver inputs function as VMO and VPO. When MODE = LOW, the single-ended input data interface mode is selected. The 2 driver inputs function as FSE0 and VO. 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. 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. The CM240001HB 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 pull-up resistor in and out without the need for external circuitry.
