CDP1851 Description
THE CDP1851 and CDP1851C are CMOS programmable twoport I/Os designed for use as general-purpose I/O devices. They are directly patible 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 peripheral devices such as printers and keyboards.
