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)
