Description
The Rockwell CMOS R68C552 Dual Asynchronous Communications Interface Adapter (DACIA) provides an easily implemented, program controlled two-channel interface between 16-bit microprocessor-based systems and serial communication data sets and modems.
Features
- Low power CMOS N-well silicon gate technology.
- Two independent full duplex channels with buffered receivers
and transmitters.
- Data seUmodem control functions.
- Internal baud rate generator with 15 programmable baud rates
(50 bps to 38,400 bps).
- Program-selectable internally or externally controlled receiver
and transmitter bit rates.
- Programmable word lengths, number of stop bits, and parity
bit generation and detection.
- Programmabl.
