产品概览
The FT232RL-REEL from FTDI is a single-chip USB to serial UART interface IC in 28-pin SSOP. It handles the entire USB protocol on-chip, requiring no firmware programming. Integrates internal EEPROM, clock generation, USB termination resistors, and 3.3V LDO. Supports 300 baud to 3 Mbaud with FTDIChip-ID security and bit-bang modes.
