1802
An 8-bit microprocessor manufactured as CDP1802 by HARRIS Semiconductor. It has been around for ten years at least and is ideally suited for embedded applications. Some of its features are: 8-bit parallel organisation with bidirectional data bus and multiplexed address bus; static design -- no minimum clock rate; bit-programmable output port; four input pins which are directly tested by branch instructions; flexible programmable I/O mode; single-phase clock, with on-chip oscillator; 16 x 16 register matrix to implement multiple program counters, pointers, or registers
