The SCC2698B Enhanced Octal Universal AsynchronousReceiver/Transmitter (Octal UART) is a single chip MOS-LSIcommunications device that provides eight full-duplex asynchronousreceiver/transmitter channels in a single package. It is fabricatedwith CMOS technology which combines the benefits of high densityand low power consumption.The operating speed of each receiver and transmitter can beselected independently as one of 26 fixed baud rates, a 16X clockderived from a programmable counter/timer, or an external 1X or16X clock. The baud rate generator and counter/timer can operatedirectly from a crystal or from external clock inputs. The ability toindependently program the operating speed of the receiver andtransmitter make the Octal UART particularly attractive fordual-speed channel applications such as clustered terminalsystems.The receiver is quadruple buffered to minimize the potential ofreceiver overrun or to reduce interrupt overhead in interrupt drivensystems. In addition, a handshaking (RTS/CTS) capability isprovided to disable a remote UART transmitter when the receiverbuffer 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 OctalUART is fully TTL compatible and operates from a single +5V powersupply.The SCC2698B is an upwardly compatible version of the 2698AOctal UART. In PLCC packaging, it is enhanced by the addition ofreceiver ready or FIFO full status outputs, and transmitter emptystatus outputs for each channel on 16 multipurpose I/O pins. Themultipurpose pins of the 2698B RIO pins, thus DMA and modemcontrol is provided.
