COM1863 - SMSC

COM1863 Universal Asynchronous Receiver/Transmitter

The Universal Asynchronous Receiver/Transmitter is an MaS/LSI monol ithic circuit that performs all the receiving and transmitting functions associated with asynchronous data communications. This circuit is fabricated using SMC's patented COPLAMOS® technology and employs depletion mode loads, allowing operation from a single +5V supply. The duplex mode, baud.

Features

o Compatible with TR1863 timing o High accuracy 32X clock mode: 48.4375% Receiver Distortion Immunity and improved RDA/ROR operation (COM 8018 only) o High Speed Operation-62.5K baud, 200ns strobes o Single +5V Power Supply o Direct TTL Compatibility-no interfacing circuits required o Input pull-up options: COM 8018 has low current pull-up resistors; COM 1863 has no pull up resistors o Full or Half Duplex Operation-can receive and transmit simultaneously at different baud rates o Fully Double Buffered-eliminates need for precise external timing o Improved Start Bit Verification -decreases erro.
