The RCA CDP1851 and CDP1851C are CMOS programmable two-port I/Os designed for use as general-purpose 1/0 devices. They are directly compatible with CDP1800 series microprocessors functioning at maximum clock frequency. Each port can be programmed in either byte-I/O or bit-programmable modes for interfacing with peri.
