SC16C550B - NXP Semiconductors

SC16C550B UART

The SC16C550B is a Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa. The UART can handle serial data rates up to 3 Mbit/s. The SC16C550B is pin compatible with the ST16C550, TL16C550 and PC16C550, and it will power-up to be functiona.
