SC/MP was an 8-bit single-chip microprocessor first introduced by National Semiconductor in 1974 in P-MOS technology. From 1975 it was released in N-Channel MOS, with +5 VDC single supply. Its architecture was very clean and efficient:

  • 16-bit program counter
  • 8-bit bidirectional data bus
  • 12-bit address bus
  • Three additional 16-bit internal registers
  • Internal clock generator, up to 4 MHz
  • Two inputs usable as interrupt lines, three flag lines usable as outputs
  • Serial input/output
  • Three-state control of the esternal buses with multiprocessing capability
  • DIP-40 package

National Semiconductor offered a Low-Cost Development System, LCDS, with hexadecimal keyboard and 7-segment display. Also available a cross-assembler running on the UDS development system.

New code for the INS8060 SC/MP microprocessor.
