UTLINE

The S1C63656 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU,

ROM (6,144 words

13 bits), RAM (1,024 words

4 bits), multiply-divide circuit, serial interface, watchdog

timer, programmable timer, time base counters (2 systems), an LCD driver that can drive a maximum 38
segments
