• Manufacturer Part Number: ft8u245am
• Description: Usb Fifo - Fast Parallel Data Transfer Ic
• Manufacturer: Future Technology Devices International Ltd.

FIFO Transmit Buffer ( 384 bytes )
Data written into the FIFO using WR# is stored in the FIFO Transmit Buffer. The Host removes Data
from the FIFO Transmit Data by sending a USB request for data from the device data in endpoint.
FIFO Controller
The FIFO Controller handles the transfer of data between the external FIFO interface pins and the FIFO
Transmit and Receive buffers.
EEPROM Interface
The FT8U245AM uses an external 93C46 EEPROM to customise the USB VID, PID, Serial Number and
Strings of the FT8U245AM for OEM applications. The FT8U245 Virtual Com Port Drivers rely on a unique
device serial number for to bind a unique virtual COM port to each individual device.
