NAME AND FUNCTION

Not Connected.

I

System Interface Supply Voltage (1.6V to 3.6V). Provides reference supply

voltage for system I/O interface signals.

I

Edge Rate Control. A logic HIGH operates at edge rates for “fullspeed”

operation. A logic LOW operates edge rates for “lowspeed” operation.

O Receive Data. Output for USB differential data. (see Table 2)

I/O

If OE# = H, VP = Receiver output (+)

If OE# = L, VP = Driver input (+) (see Table 2)

I/O

If OE# = H, VM = Receiver output (-)

If OE# = L, VM = Driver input (-) (see Table 2)

I CONNECT (input). Controls state of VPU. Refer to VPU pin description for detail.

Ground Reference

I Suspend (active-high). Turns off internal circuits to reduce supply current.

Output Enable (active-low). Enables transceiver data transmission onto the bus.

I

When not active, the transceiver is in the receive mode. (see Table 2)

I/O Differential data lines. (see Table 2)

O

3.3V Reference Supply Output. Requires a 1.0µF decoupling capacitor for

stability.

Pull-up Supply Voltage Output. Used to connect 1.5kΩ pull-up speed detect

O resistor. If CON = 0, VPU is high impedance. If CON = 1, VPU = 3.3V ±10%.

I

USB Bus Supply Voltage (4V to 5.5V). Supplies power to the USB transceiver

and internal circuitry.

Not connected.

O

VBUS indicator output. When VBUS > 2.9V, VBUSDET = High and when < 2.2V,

VBUSDET = Low.
