FT231XS-U
Overview
The FT231XS-U is a compact USB-to-UART bridge IC designed to facilitate Full Speed USB 2.0 communication for embedded systems. It features an integrated MTP-ROM for device configuration and supports supply voltages between 3.3V and 5V. The device simplifies the transition from legacy serial designs to USB by handling the entire USB protocol on-chip.
Why Choose This Part
This IC reduces BOM cost and PCB area by integrating the clock circuit and MTP-ROM, eliminating the need for an external crystal or EEPROM. It offers low power consumption with a typical supply current of 8mA and a dedicated USB suspend mode. The inclusion of four configurable GPIO pins provides additional flexibility for status LEDs or handshake signals.
Applications
Key Specifications
Getting Started
To evaluate this chip, use the UMFT231XB development module or connect the 20-SSOP package to a breadboard using an adapter. FTDI provides Royalty-Free Virtual COM Port (VCP) and D2XX drivers for Windows, Linux, and macOS. Configuration of the internal MTP-ROM can be performed using the FT_PROG utility.
