• Description: Ft232h Single Channel Hi- Speed Usb To Multipurpose Uart/fifo Ic
• Manufacturer: Future Technology Devices International Ltd.

7.2 Default EEPROM Configuration
The external EEPROM (if it‟s fitted) can be programmed over USB using FT_Prog. This allows a blank part
to be soldered onto the PCB and programmed as part of the manufacturing and test process. Users who
do not have their own USB Vendor ID but who would like to use a unique Product ID in their design can
apply to FTDI for a free block of unique PIDs.

A unique serial number is generated and
programmed into the EEPROM during device
final test.
Enabling this option will make the device pull
down on the UART interface lines when in USB
suspend mode (PWREN# is high).
Returns USB 2.0 device description to the host.
Note: The device is a USB 2.0 Full Speed device
(12Mb/s) as opposed to a USB 2.0 Hi-Speed
device (480Mb/s).
Taking RI# low will wake up the USB host
controller from suspend in approximately 20
ms.
Allows the user to select the hardware mode of
the device. Options include: RS232 UART, 245
FIFO, CPU 245, OPTO Isolate and FT1248.
FT1248 can be configured to set: Clock Polarity
High; Bit Order LSB and Flow Control Not
Selected.
Enters low power state on ACBus7.
Makes the device load the VCP driver interface
Enables the high drive level on the UART and
ACBUS I/O pins.
