UM232H Single Channel USB Hi-Speed FT232H Development Module

Datasheet Version 1.2

Clearance No.: FTDI# 198

9 EEPROM Configuration

The FT232H uses an external EEPROM (on the UM232H module). This EEPROM can be programmed over

USB using FT_Prog. The default settings of the EEPROM are shown in the following table:

Parameter

Value

Notes

USB Vendor ID (VID)

0403h

FTDI default VID (hex)

USB Product UD (PID)

6014h

FTDI default PID (hex)

bcd Device

009h

Serial Number Enabled?

Yes

Serial Number

See Note

A unique serial number is generated and programmed

into the EEPROM during device final test.

Pull down I/O Pins in USB

Suspend

Disabled

Enabling this option will make the device pull down

on the UART interface lines when in USB suspend

mode (PWREN# is high).
