Overview
The SC16C652BIB48,157, produced by NXP USA Inc., is a 2-channel Universal Asynchronous Receiver and Transmitter (UART) designed for serial data communications. This component is part of the SC16C652B series, which offers enhanced UART functions with support for multiple voltage levels (5 V, 3.3 V, and 2.5 V) and high-speed data transfer up to 5 Mbit/s. The SC16C652B is pin compatible with the SC16C2550 and provides backward compatibility with the 16C2450 upon power-up. It features 32-byte FIFOs for both transmit and receive operations, a modem control interface, DMA mode data transfer, and an infrared (IrDA) encoder/decoder.
