نظرة عامة على المنتج
The FT232RQ-REEL from FTDI Chip is a USB to serial UART bridge interface IC in a QFN-32 package. It integrates an entire USB protocol engine, EEPROM, clock generation circuitry, and USB termination resistors in a single chip. The device supports data transfer rates up to 3MBaud with 256-byte TX and 128-byte RX FIFO buffers, and provides multi-protocol serial interface options including RS232, RS422, and RS485.
