FT2232D-TRAY

Controllers Overview

The FT2232D-TRAY is a USB interface integrated circuit from the FT2232D series, manufactured by FTDI. It integrates two independent IO channels within a single device, eliminating the need for an external USB hub. Each channel supports configurable UART or FIFO interfaces. The component operates on a 4.35V to 5.25V supply voltage with a maximum current consumption of 30mA. It features ESD protection and functions within a temperature range of -40°C to +85°C. The device utilizes a 48-pin LQFP package measuring 7mm x 7mm with a height of 1.4mm.

Controllers Feature Summary

• Dual-channel architecture converting one downstream USB port into two independently configurable IO channels.
• Supports FT232B-style asynchronous serial UART interface with full hardware handshaking and modem signals.
• Includes FT245B-style FIFO interface option featuring a bidirectional data bus and simple four-wire handshake.
• Handles entire USB protocol internally without requiring specific USB firmware programming.

Controllers Applications

• USB to dual RS232 serial converter designs
• High-speed parallel data transfer via FIFO mode
• Synchronous Bit-Bang Mode implementations
• MCU Host Bus Emulation applications

Controllers Procurement Notes

Verify component status as the FT2232D series has been declared obsolete with an End-of-Life notice dated March 13, 2023. Confirm availability through authorized distributors for remaining stock or consider approved replacement parts such as the FT2232HL series for new designs. Ensure packaging matches the TRAY suffix requirement for procurement specifications.

Controllers Selection Notes

Select this component when a design requires two independent serial or parallel ports derived from a single USB connection. It is suitable for applications needing UART or FIFO functionality without additional hub components. Verify that the 48-pin LQFP footprint fits the PCB layout constraints and that the 5V logic levels align with the target system requirements.

Controllers Part Context

This part belongs to the FT2232D family, which combines the functionality of two second-generation BM chips into one unit. It serves as a bridge between USB hosts and various peripheral devices, supporting protocols like I2C, SPI, and UART. The TRAY suffix indicates the specific tape and reel or tray packaging configuration provided by the manufacturer.

Controllers Replacement Considerations

The FT2232HL-REEL is listed as a recommended substitute. Verify pin compatibility and electrical characteristics before substitution. Note that the HL variant may differ in package type (LQFP-64) and power specifications compared to the original D series.
