SC16C550 - NXP

SC16C550 Universal Asynchronous Receiver/Transmitter (UART) with 16-byte FIFO and infrared (IrDA) encoder/decoder

The SC16C550 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 Mbits/s. The SC16C550 is pin compatible with the ST16C550, TL16C550 and PC16C550, and it will power-up to be functional.

Features

of the SC16C550. Some of these added features are the 16-byte receive and transmit FIFOs, automatic hardware or software flow control and Infrared encoding/decoding. The selectable auto-flow control feature significantly reduces software overload and increases system efficiency while in FIFO mode by automatically controlling serial data flow using RTS output and CTS input signals. The SC16C550 also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and RXRDY signals. On-board status registers provide the user with error indications, operational status, and modem interface co.
