FT240XS-R
Overview
The FT240XS-R is a USB to parallel FIFO bridge chip that simplifies the implementation of USB 2.0 Full Speed connectivity in embedded designs. It handles the entire USB protocol on-chip, eliminating the need for complex USB firmware development. With integrated clock generation and 2048 bytes of MTP memory, it provides a compact solution for bidirectional data transfer between a host and an external MCU or FPGA.
Why Choose This Part
The device features 512-byte transmit and receive buffers with buffer smoothing technology to maintain high throughput. It integrates all necessary clocking and MTP memory for descriptors into a small 24-SSOP package, reducing BOM count by eliminating external crystals and EEPROMs. FTDI's royalty-free VCP and D2XX drivers further accelerate time-to-market by removing the requirement for custom USB driver development.
Applications
Key Specifications
Getting Started
To evaluate the FT240XS, engineers often use the UMFT240XA development module which breaks out the 24-pin SSOP interface. Drivers are available for Windows, Mac OS X, and Linux via the FTDI website. Configuration of the internal MTP memory for custom descriptors can be performed using the free FT_PROG utility over the USB interface.
