Asynchronous Communication Interface Adapter - DIP-28

The S6551 is an asynchronous communication adapter (ACIA) intended to provide interfacing for the microprocessors to serial communication data sets and modems. A unique feature is the inclusion of an on-chip programmable baud rate generator with a crystal being the only external component required.

Features

  • On-chip baud rate generator: 15 programmable baud rates derived from a standard 1.8432 MHz external crystal (50 to 19,200 baud)
  • Programmable interrupt and status register to simplify software design
  • Single +5 volt power supply
  • Serial echo mode
  • False start bit detection
  • 8-bit bi-directional data bus for direct communication with the microprocessor
  • External 16x clock input for non-standard baud rates (up to 125k baud)
  • Programmable: word lengths; number of stop bits; and parity bit generator and detection
  • Data set and modem control signals provided
  • Parity: (odd, even, none, mark, space)
  • Full-duplex or half-duplex operation
  • 5, 6, 7, 8, and 9-bit transmission
