■ DESCRIPTIONS
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.
