The SC16C752BIB48,157 is a UART Interface IC 2CH manufactured by NXP. It features two 64-byte FIFOs (first-in/first-out) for sending and receiving data. This allows the FIFOs to manage the data independently, which can improve performance in systems that have multiple transmitters and receivers. It also supports a variety of serial protocols, including asynchronous, synchronous, and HDLC asynchronous. Other features include a programmable baud rate up to 1.5Mbaud, flow control, parity, and enhanced power savings. The chip is ideal for RS-232, RS-485, and other serial applications.
