8-bit Single Chip Microcomputer

  • Original Architecture Core CPU
  • Low Current Consumption
  • Wide-range Operating Voltage (1.8V to 5.5V)
  • Built-in Melody Generator and A/D Converter „ DESCRIPTION The S1C88349 microcomputer features the S1C88 (Model 3) CMOS 8-bit core CPU along with 48K bytes of ROM, 2K bytes of RAM, three different timers, a seri al interface with optional asynchronization or clock synchronization, and an A/D converter. The S1C88349 is fully operable over a wide range of vo ltages, and can perform high speed operations even at low voltage. Like all the equipment in the S1C Family, these microcomputers have low power consumption. A 19-bit external address bus and 4 bits chip enable signals make it possible for this microcomputer to control up to 512K × 4 bytes of memory, making them ideal for high performance data bank systems. „ FEATURES Core CPU S1C88 (MODEL3) CMOS 8-bit core CPU OSC1 oscillation circuit Crystal oscillation circuit/CR oscillation circuit/external clock input 32.768 kHz (Typ.)
