• 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 115.2 kb– Non-standard user-defined rate derived from programmabletimer/ 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
The Philips Semiconductors SCC2691 Universal AsynchronousReceiver/Transmitter (UART) is a single-chip CMOS-LSIcommunications device that provides a full-duplex asynchronousreceiver/transmitter. It is fabricated with Philips SemiconductorsCMOS technology which combines the benefits of high density andlow power consumption.The operating speed of the receiver and transmitter can be selectedindependently as one of 18 fixed baud rates, a 16X clock derivedfrom a programmable counter/timer, or an external 1X or 16X clock.The baud rate generator and counter/timer can operate directly froma crystal or from external clock inputs. The ability to independentlyprogram the operating speed of the receiver and transmitter makethe UART particularly attractive for dual-speed channel applicationssuch as clustered terminal systems.The receiver is quadruple buffered to minimize the potential ofreceiver overrun or to reduce interrupt overhead in interrupt drivensystems. In addition, a handshaking capability is provided to disablea remote UART transmitter when the receiver buffer is full.The UART provides a power-down mode in which the oscillator isfrozen but the register contents are stored. This results in reducedpower consumption on the order of several magnitudes.The UART is fully TTL compatible and operates from a single +5Vpower supply.
