Description
1
OE#
I Active low output enable signal
2
RCV
O
Differential receiver output. Stable output during SE0. This pin has an internal 220
kΩ pull-down to ground when HIGHZ=”H” only.
3
VP
O
Standard Mode: USB D+ receiver output. This pin has an internal 220 kΩ pull-down
to ground when HIGHZ=”H” only.
4
VM
O
Standard Mode: USB D- receiver output. This pin has an internal 220 kΩ pull-down
to ground when HIGHZ=”H” only.
Normally used as Suspend input (active high). Puts the transceiver in low power
5 SUSPEND I consumption mode. Functionality can change depending on status of SPEED# and
SOFTCON pins. See Table 12 for more details.
6
HIGHZ
I
Sets to high impedance for production flash. This pin has an internal 220 kΩ pull-
down to ground always connected.
7
VCC_IO PWR Supply voltage for digital I/O pins (1.6 V to 3.6 V)
Normally used as Speed selection input. A logic LOW adjusts the slew rate of D+/D-
8
SPEED#
I
USB differential signals for Full-speed operation. Set to HIGH for Low-speed
operation. Functionality can change depending on status of SUSPEND and
SOFTCON pins. See Table 12 for more details.
