FT232H SINGLE CHANNEL HI-SPEED USB TO MULTIPURPOSE UART/FIFO IC
Datasheet Version 1.8
Clearance No.: FTDI #199
Pin No.
Name
Type
Description
45
EECS
I/O
EEPROM – Chip Select. Tri-State during device reset.
44
EECLK
OUTPUT
Clock signal to EEPROM. Tri-State during device reset. When not in reset, this
outputs the EEPROM clock.
43
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 VCCD
via a 10K resistor for correct operation. Tri-State during device reset.
