6551 ASYNCHRONOUS COMMUNICATION INTERFACE ADAPTER CONCEPT: The 6551 is an Asynchronous Communication Adapter (ACIA) intended to provide for interfacing the 6500/6800 microprocessor families 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 com pone t required. FEATURES: • On-chip baud rate generator: 15 programmable baud rates derived from a standard 1.8432 M Hz external crystal (50 to 19,200 baud). • Programmable interrupt and status register to simplify software design. • Single +5 volt power supply. • Se
