FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC
Datasheet Version 2.2
Clearance No.: FTDI#78
Pin No.
Name
Type
Description
2
OSCI
INPUT
Oscillator input.
3
OSCO
OUTPUT
Oscillator output.
6
REF
INPUT
Current reference – connect via a 12K Ohm resistor @ 1% to GND.
7
DM
INPUT
USB Data Signal Minus.
8
DP
INPUT
USB Data Signal Plus.
13
TEST
INPUT
IC test pin – for normal operation should be connected to GND.
14
RESET#
INPUT
Reset input (active low).
60
PWREN#
OUTPUT
Active low power-enable output.
PWREN# = 0: Normal operation.
PWREN# =1 : USB SUSPEND mode or device has not been configured.
This can be used by external circuitry to power down logic when device
is in USB suspend or has not been configured.
36
SUSPEND#
OUTPUT
Active low when USB is in suspend mode.

Description
63
EECS
I/O
EEPROM – Chip Select. Tri-State during device reset.
62
EECLK
OUTPUT
Clock signal to EEPROM. Tri-State during device reset. When not in reset, this
outputs the EEPROM clock.
61
EEDATA
I/O
EEPROM – Data I/O Connect directly to Data-In of the EEPROM and to Data-Out
of the EEPROM via a 2.2K resistor. Also, pull Data-Out of the EEPROM to VCC via
a 10K resistor for correct operation. Tri-State during device reset.
