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

• Line break detection and generation

• Programmable channel mode

– Normal (full-duplex)

– Automatic echo

– Local loopback

– Remote Loopback

• Multi-function programmable 16-bit counter/timer

• Single interrupt output with seven maskable interrupting conditions

• On-chip crystal oscillator

• Low power mode

• TTL compatible

• Single +5V power supply

• Commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature versions available

• SOL, PLCC and 300 mil wide DIP packages available
