1OUTLINE
The S1C63653 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU,
ROM (4,096 words
× 13 bits), RAM (512 words × 4 bits), watchdog timer, programmable timer, time base
counter, an LCD driver that can drive a maximum 32 segments
× 6 commons, sound generator and R/f
converter built-in. The S1C63653 features low current consumption, this makes it suitable for battery driven
portable equipment with R/f converter.
