FT240XS-R

Controllers Overview

The FT240XS-R is a USB to 8-bit FIFO interface controller manufactured by Future Technology Devices International Ltd. It operates as a high-speed bridge between Universal Serial Bus and parallel data ports, supporting Full Speed USB 2.0 with a maximum data rate of 12 Mb/s on the host side and up to 1 Mbit/s on the parallel FIFO interface. The device integrates 512-byte transmit and receive FIFOs to manage data flow efficiently. It functions within a supply voltage range of 2.97 V to 5.5 V and includes built-in transmitter and receiver FIFO counters for status monitoring. The component is designed for surface mount installation in an SSOP-24 package and supports operation across an industrial temperature range from -40°C to +85°C.

Controllers Feature Summary

• Provides asynchronous 8-bit parallel data transfer via dedicated FIFO interface
• Integrates dual 512-byte buffers for independent transmit and receive operations
• Supports standard SIE protocol for direct USB communication handling

Controllers Applications

• High-speed data acquisition systems requiring parallel-to-USB conversion
• Industrial control interfaces connecting PLCs or sensors to PC hosts
• Embedded development platforms utilizing bulk data transfer capabilities

Controllers Procurement Notes

Verify the specific suffix designation against official FTDI documentation to confirm exact packaging configuration and compliance status. Ensure the procurement source provides valid traceability for the SSOP-24 package variant. Cross-reference the manufacturing date code with current production lifecycle notices to confirm active availability and long-term supply stability for integration projects.

Controllers Selection Notes

Select this component when an 8-bit wide parallel interface is required rather than UART or SPI protocols. The FT240XS-R is appropriate for applications needing synchronous data strobing without external clock generation. Consider the 512-byte buffer depth for burst transmission requirements. Verify that the target system can accommodate the SSOP-24 footprint and meets the 2.97V to 5.5V power supply constraints defined in the electrical specifications.

Controllers Part Context

This part belongs to the FT240X series of USB FIFO controllers, which are distinct from FTDI's UART-based products like the FT232 or FT234XD. Unlike single-channel serial bridges, the FT240XS-R focuses on high-throughput parallel data movement. It serves as a specialized interface solution for legacy parallel peripherals or custom digital logic interfacing with modern USB hosts.

Controllers Replacement Considerations

Direct pin-compatible replacements are limited within the same family. Evaluate the UMFT240XE development module for prototyping purposes. For mass production, verify if newer revisions of the FT240XS exist with updated packaging or compliance markings before substituting.
