D404222C89S Integrated Circuit HITACHI CMOS 4-bit Single-chip Microcomputers

CMOS 4-bit Single-chip Microcomputers with the same Architecture as the Hmcs400 Series

  • Manufacturer: Hitachi
  • Family: HD404220 Series (4-bit Single-chip Microcomputer, CMOS technology)
  • Package: 42-pin DIP ("Shrink" structure / S-type)
  • Architecture:
    • 4-bit CPU
    • Internal ROM memory (mask programmed, specific to the C89S code)
    • Internal RAM memory
  • Main features: Timers, parallel I/O ports, A/D converter (depending on 404220 series variants), interrupt system.
  • Supply voltage: Typically 3V - 5V (CMOS standard).
  • Typical applications: Vintage consumer electronics (e.g. VCRs, advanced remote controls, small household appliances, calculators).

Note: As this is a microcontroller with mask ROM (C89S indicates a custom version with specific Hitachi firmware), the exact pinout and programming specifications depend entirely on the original application for which it was commissioned.
