Symbol[1]
Pin Type Description
n.c.
48 -
no connection; leave this pin open
n.c.
49 -
no connection; leave this pin open
H_DM1
50 AI/O USB D− data line for HC downstream port 1
H_DP1
51 AI/O USB D+ data line for HC downstream port 1
H_DM2
52 AI/O
USB D− data line for HC downstream port 2; when not in
use, this pin must be left open
H_DP2
53 AI/O
USB D+ data line for HC downstream port 2; when not in
use, this pin must be left open
H_OC1_N
54 I
overcurrent sensing input for HC downstream port 1
H_OC2_N
55 I
overcurrent sensing input for HC downstream port 2
VCC
56 -
digital power supply input (3.0 V to 3.6 V or
4.75 V to 5.25 V). This pin supplies the internal 3.3 V
regulator input. When connected to 5 V, the internal
regulator will output 3.3 V to pins VREG(3V3), VHOLD1 and
VHOLD2. When connected to 3.3 V, it will bypass the internal
regulator.
AGND
57 -
analog ground
VREG(3V3)
58 -
internal 3.3 V regulator output; when pin VCC is connected
to 5 V, this pin outputs 3.3 V. When pin VCC is connected to
3.3 V, connect this pin to 3.3 V.
A0
59 I
address input; selects command (A0 = 1) or data (A0 = 0)
LOW_PW
60 I
if low-current consumption (range of µs) is needed during
suspend, connect this pin to address A1; otherwise,
connect to DGND
n.c.
61 -
no connection; leave this pin open
DGND
62 -
digital ground
D0
63 I/O
bit 0 of bidirectional data; slew-rate controlled; TTL input;
three-state output
D1
64 I/O
bit 1 of bidirectional data; slew-rate controlled; TTL input;
three-state output
[1] Symbol names ending with underscore N (for example, NAME_N) represent active LOW signals.
