Overview
The FT2232D-TRAY, produced by FTDI, Future Technology Devices International Ltd, is a dual USB to serial UART or FIFO interface IC. This component integrates the functionality of two second-generation FTDI chips, the FT232BM and FT245BM, into a single device. It provides a single downstream USB port that can be converted into two individually configurable IO channels, each capable of operating as either a UART or FIFO interface. The FT2232D handles the entire USB protocol on the chip, eliminating the need for USB-specific firmware programming. This makes it a versatile and efficient solution for various serial and parallel interface applications.
