The ST16C554Q is a high-performance quad Universal Asynchronous Receiver/Transmitter (UART) IC designed to provide efficient serial communication for embedded systems. It features four independent UART channels, each with a 16-byte FIFO for transmit and receive operations, which minimizes CPU overhead and enhances system performance. The device supports data rates of up to 1.5 Mbps and is equipped with a parallel interface for integration into microcontroller or processor-based systems. Encased in a 64-QFP package, the ST16C554Q is ideal for space-constrained designs and is suitable for a wide range of industrial, communication, and embedded applications.
