Overview
STANDARD MICROSYSTEMS CORPORATION COM 1863 COM 8018 j1PC FAMILY Universal Asynchronous Receiver/Transmitter UART 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 error rate 046.
875% Receiver Distortion Immunity o Fully Programmable-data word length; parity mode; number of stop bits: one, one and one-half, or two o Master Reset-Resets all status outputs and Receiver Buffer Register o Three State Outputs-bus structure oriented o Low Power-minimum power requirements o Input Protected-eliminates handling problems o Ceramic or Plastic DIP Package-easy board insertion o Baud Rates available from SMC's COM 8046, COM 8116, COM 8126, COM 8136, COM 8146 baud rate generators PIN CONFIGURATION VOO 'HIACC Gnd ROE RD8 RD7 RD6 RD5 RD4 RD3 RD2 RD1 RPE RFE ROR SWE RCP RDA RSI [ '7 1 2 3 4 5 6 7 8 09 10 11 12 13 14 15 16 17 18 19 20 40 TCP 39 POE 38 NDB1 37 NDB2 36 NSB 35 NPB 34 CS 33 TD8 32 TD7 31 TD6 30 TD5 29 TD4 28 TD3 27 TD2 26 TD1 25 TSO 24 TEOC 23 TI5S 22 TBMT b21 MR PACKAGE: 40-Pin D.
