DESCRIPTION
The Philips Semiconductors SCC2681 Dual Universal Asynchronous Receiver/Transmitter (DUART) is a single-chip MOS-LSI communications device that provides two independent full-duplex asynchronous receiver/transmitter channels in a single package. It interfaces directly with microprocessors and may be used in a polled or interrupt driven system. It is manufactured in a CMOS process.
FEATURES
? Dual full-duplex asynchronous receiver/transmitter
? Quadruple buffered receiver data registers
? 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
? Programmable baud rate for each receiver and transmitter selectable from:
– 22 fixed rates: 50 to 115.2 k baud
? 16-bit programmable Counter/Timer
– Non-standard rates to 115.2 kb
– One user-defined rate derived from programmable timer/counter
– External 1× or 16× clock
? Parity, framing, and overrun error 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
? Multi-function 7-bit input port
– Can serve as clock or control inputs
– Change of state detection on four inputs
– 100 k? typical pull-up resistor
? Multi-function 8-bit output port
– Individual bit set/reset capability
– Outputs can be programmed to be status/interrupt signals
– DMA signals
– Auto 485 turn-around
? Versatile interrupt system
– Single interrupt output with eight maskable interrupting conditions
– Output port can be configured to provide a total of up to six separate wire-ORable interrupt outputs
? Maximum data transfer: 1× – 1 MB/sec; 16× – 125 kB/sec
? Automatic wake-up mode for multidrop applications
? Start-end break interrupt/status
? Detects break which originates in the middle of a character
? On-chip crystal oscillator
? Single +5 V power supply
? Commercial and industrial temperature ranges available
? DIP and PLCC packages
