C232HD USB 2.0 HI-SPEED TO UART CABLE Datasheet

Version 1.3

Document No.: FT_000430 Clearance No.: FTDI# 222

Appendix A - Cable EEPROM Configuration

Each C232HD cable is controlled by the FTDI FT232H IC. This cable contains an EEPROM which contains

the USB configuration descriptors for that device. When the cable is plugged into a PC or a USB reset is

performed, the PC will read these descriptors. The default values stored into the internal EEPROM are

defined in the following table.

Parameter

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 the power is shut

off (PWREN# is high).
