NAME AND FUNCTION
Not Connected.
I
System Interface Supply Voltage (1.6V to 3.6V). (return) 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 V_PU. Refer to V_PU 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 that conform to the USB v2.0 standard. (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 1.5K 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
V_BUS indicator output. When V_BUS > 2.9V, V_BUSDET = High and when < 2.2V,
V_BUDET = Low.
