NAME
FUNCTION
15
18
B4
INT
Active-Low Interrupt Source. Program the
INT output as push-pull or open-
drain with the irq_mode bit (bit 1 of special-function register 2, see Tables 15
and 16).
16
19
B5
RESET
Active-Low Reset Input. Drive
RESET low to asynchronously reset the
MAX3301E/MAX3302E.
17
20
C3
ADD
I2C-Interface Address Selection Input. (See Table 5.)
19
22
C4
ID_IN
ID Input. ID_IN is internally pulled up to VCC. The state of ID_IN determines
ID bits 3 and 5 of the interrupt source register (see Table 10).
20
23
D5
D-
USB Differential Data Input/Output. Connect D- to the D- terminal of the USB
connector through a 27.4
Ω ±1% series resistor.
21
24
E5
D+
USB Differential Data Input/Output. Connect D+ to the D+ terminal of the USB
connector through a 27.4
Ω ±1% series resistor.
22
26
D4
VM
Single-Ended Receiver Output. VM functions as a receiver output in all
operating modes. VM duplicates D-.
24
27
E4
TRM
USB Transceiver Regulated Output Voltage. TRM provides a regulated 3.3V
output. Bypass TRM to GND with a 1F ceramic capacitor installed as close
to the device as possible. TRM normally derives power from VCC. TRM
provides power to internal circuitry and provides the pullup voltage for the
internal USB pullup resistor. Do not use TRM to power external circuitry. The
reg_sel bit (bit 3 of special-function register 2, see Table 15 and Table 16)
controls the TRM power source with software.
26
30
D3
VP
Single-Ended Receiver Output. VP functions as a receiver output in all
operating modes. VP duplicates D+.
27
31
E2
VBUS
USB Bus Power. Use VBUS as an output to power the USB bus, or as an input
to power the internal linear regulator. Bits 5 to 7 of control register 2 (see
Table 8) control the charging and discharging functions of VBUS.

E1
C+
Charge-Pump Flying-Capacitor Positive Terminal
EP

EP
Exposed Paddle. Connect EP to GND or leave unconnected.
