FT232H SINGLE CHANNEL HI-SPEED USB TO MULTIPURPOSE UART/FIFO IC

Datasheet Version 1.3

Clearance No.: FTDI #199

Configurable ACBUS I/O Pin. Function of this pin is configured in the device

EEPROM. If the external EEPROM is not fitted the default configuration is TriSt-PU.

See ACBUS Signal Options, Table 3.5.

Configurable ACBUS I/O Pin. Function of this pin is configured in the device

EEPROM. If the external EEPROM is not fitted the default configuration is TriSt-PD.

Notes:

1. When used in Input Mode, the input pins are pulled to VCCIO via internal 75kΩ (approx) resistors.

These pins can be programmed to gently pull low during USB suspend (PWREN# = “1”) by setting an

option in the EEPROM.
