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

k

Ω pull-down to ground when HIGHZ=”H” only.

3VP

O

Standard Mode: USB D+ receiver output. This pin has an internal 220 k

Ω pull-down

to ground when HIGHZ=”H” only.

4VM

O

Standard Mode: USB D- receiver output. This pin has an internal 220 k

Ω pull-down

to ground when HIGHZ=”H” only.

5

SUSPEND

I

Normally used as Suspend input (active high). Puts the transceiver in low power

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 k

Ω pull-

down to ground always connected.

PWR

Supply voltage for digital I/O pins (1.6 V to 3.6 V)

8

SPEED#

I

Normally used as Speed selection input. A logic LOW adjusts the slew rate of D+/D-

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.

D-

AI/O

USB Mode: Negative USB data line

10

D+

AI/O

USB Mode: Positive USB data line

11

VO

I

USB differential driver data input

12

FSE0

I

Standard Mode: Force single-ended zero data input. This pin has an internal 220 k

Ω

pull-down to ground when HIGHZ=”H” only.

13

PWR

Analog supply voltage input (3.0 V to 3.6 V). Left floating brings the device into

sharing mode.
