FTDI Chip Full Speed USB to UART Interface IC, RS232 RS422 UART RS485 Compatible, 16-Pin QFN Package FT230XQ-R

FTDI Chip FT230XQ-R is a Full Speed USB to UART interface integrated circuit designed to bridge USB communication to serial UART interfaces, supporting popular protocols including RS232, RS422, UART, and RS485. It utilizes a 16-pin QFN surface mount package measuring 4 mm in length and 800 μm in height, suitable for compact PCB layouts.

This device integrates advanced features such as fully integrated MTP memory, internal clock generation requiring no external crystal, AVCC filtering, power-on reset circuits, and low dropout (LDO) regulators, which reduce the number of external components and simplify system designs.

It supports a maximum data rate of 3 MBaud with 512-bit FIFO buffers for both transmit and receive paths to handle bursts of data efficiently, minimizing communication delays and buffering issues. The FT230XQ-R operates across a broad supply voltage range from 3.3 V up to 5.25 V and sustains functionality over a wide industrial temperature range from -40°C to 85°C, making it suitable for demanding environments.

The device achieves low power consumption, drawing approximately 8 mA during nominal operation and only 125 μA during USB suspend mode, making it energy-efficient for battery-powered or low-power applications.

Its surface mount QFN package and compliance with USB specifications allow quick integration into embedded control, industrial automation, and communication systems requiring a reliable USB-to-serial interface. The driver interface is supported across multiple operating systems, simplifying deployment.
