Ft231x Usb Uart Jun 2026

The FT231X represents a mature, optimized solution for USB-to-UART bridging. By encapsulating the complexity of USB protocols into a hardware abstraction layer, it allows embedded engineers to focus on application development rather than interface driver engineering. Its balance of size, configurability (specifically the CBUS pins), and robust driver support ensures its continued relevance in the embedded systems landscape for the foreseeable future.

: It typically consumes only 8mA during active operation and drops to 125µA in suspend mode. Technical Specifications Specification Data Transfer Rates 300 baud to 3 Mbaud USB Version USB 2.0 Full Speed (12Mbps) UART Interface 7 or 8 data bits, 1 or 2 stop bits, various parity options Internal Buffer 512-byte receive buffer and 512-byte transmit buffer Operating Temperature -40°C to +85°C (Industrial Grade) Package Options 20-pin SSOP (FT231XS) or 20-pin QFN (FT231XQ) Comparing FT231X vs. FT232R vs. FT230X ft231x usb uart

: The chip generates its own clock (6MHz, 12MHz, and 24MHz), which removes the requirement for an external crystal and saves board space. The FT231X represents a mature, optimized solution for

The most ubiquitous use of the FT231X is as a USB-to-Serial adapter dongle. It is frequently used to program Arduino-compatible boards (bootloader flashing) and debug ESP32, STM32, and ARM Cortex-M microcontrollers via their UART bootloaders or SWD interfaces (when combined with specific software). : It typically consumes only 8mA during active
