Pin Functions

PIN I/O INTERNAL
PULLUP/PULLDOWN		 DESCRIPTION
NAME NO.
VCC 12 P N/A 3.3-V power
VREG 11 O RSTN asserted: 30 kΩ PD 1.8-V LDO output. Only enabled when operating in High Speed mode. Requires 0.1-µF external capacitor to GND to stabilize the core.
FS, LS mode: 30 kΩ PD
HS mode: N/A
GND 10 P N/A Ground
RSTN 5 I 500 kΩ PU Device disable/enable.
Recommend 0.1-µF external capacitor to GND to ensure clean power on reset if not driven.
EQ 6 I N/A USB High Speed boost select via external pull down resistor.
Sampled upon power up.
Auto selects min EQ when left floating.
Does not recognize real time adjustments.
D1P 2 I/O N/A USB High Speed positive port.
Orientation independent – Can face either upstream or downstream.
D1M 1 I/O N/A USB High Speed negative port.
Orientation independent – Can face either upstream or downstream.
D2P 7 I/O N/A USB High Speed positive port.
Orientation independent – Can face either upstream or downstream.
D2M 8 I/O N/A USB High Speed negative port.
Orientation independent – Can face either upstream or downstream.
TEST 3 I RSTN asserted: 500 kΩ PD No function. Leave floating.
ENA_HS 9 O RSTN asserted: 500kΩ PD Flag indicating that channel is in High Speed mode. Asserted upon:
  1. Detection of USB-IF High Speed test fixture from an unconnected state followed by transmission of USB TEST_PACKET pattern.
  2. Squelch detection following USB reset with a successful HS handshake [HS handshake is declared to be successful after single chirp J chirp K pair where each chirp is within 18 µs – 128 µs]

De-asserted upon detection of disconnect or suspend.
Can be left floating if not needed.
CD 4 O RSTN asserted: 500 kΩ PD Flag indicating that a USB device is attached.
Asserted from an unconnected state upon detection of DP or DM pull-up resistor.
De-asserted upon detection of disconnect.
Can be left floating if not needed.
