Product Summary
The R6551P is an asynchronous communications interface adapter (ACIA) provides an easily implemented, program conntrolled interface between 8-bit microproceesor-based systems and serial communication data sets and modems. The device has an internal baud rate generator. The R6551P is designed for maximum programmed control from the microprocessor, to simplify hardware implementation.
Parametrics
R6551P absolute maximum ratings: (1)supply voltage, VCC: -0.3 to 7.0Vdc; (2)input voltage, VIN: -0.3 to VCC; (3)output voltage, VOUT: -0.3 to VCC; (4)operating temperature, TA: 0 to 70℃; (5)storage temperature, Tstg: -55 to 150℃.
Features
R6551P features: (1)compatible with 8-bit microprocessors; (2)full duplex operation with buffered receiver and transmitter; (3)data set/modem control functions; (4)internal baud rate generator with 15 orogrammable baud rates (50 to 19200); (5)prgram-selectable internally or externally controlled receiver rate; (6)programmable word lengths, number of stop bits, and parity bit geration and detection; (7)programmable interrupt control; (8)program reset; (9)program-selectable serial echo mode; (10)two chip selects; (11)2 or 1 MHz operation; (12)5.0 Vdc±5% supply requirements; (13)28-pin plastic or ceramic DIP; (14)full TTL compatibility.
