Overview
The SC16C554BIB64,128, produced by NXP USA Inc., is a 4-channel Universal Asynchronous Receiver and Transmitter (QUART) designed for serial data communications. This component is part of the SC16C554B/554DB family and is fabricated using an advanced CMOS process to achieve low power consumption and high-speed requirements. It is pin compatible with the ST16C554 and TL16C554 and powers up to be functionally equivalent to the 16C454, with additional enhanced features such as 16-byte receive and transmit FIFOs.
