DESCRIPTION

The Philips Semiconductors SCC2691 Universal Asynchronous Receiver/Transmitter (UART) is a single-chip CMOS-LSI communications device that provides a full-duplex asynchronous receiver/transmitter. It is fabricated with Philips Semiconductors CMOS technology which combines the benefits of high density and low power consumption.

FEATURES

? Full-duplex asynchronous receiver/transmitter

? Quadruple buffered receiver data register

? Programmable data format:

– 5 to 8 data bits plus parity

– Odd, even, no parity or force parity

– 1, 1.5 or 2 stop bits programmable in 1/16-bit increments

? 16-bit programmable Counter/Timer

? Baud rate for the receiver and transmitter selectable from:

– 22 fixed rates: 50 to 115.2K baud

– Non-standard rates to 115.2kb

– Non-standard user-defined rate derived from programmable timer/ counter

– External 1X or 16X clock

? Parity, framing, and overrun detection

? False start bit detection
