4-bit Single Chip Microcomputer
Original Architecture Core CPU
Low Current Consumption
High Speed Operation in Low Voltage
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 ×
4 commons, sound generator, R/f converter and stepping motor driver built-in. The S1C63656 features low
current consumption, this makes it suitable for battery driven clocks and watches with temperature and humidity
measurement functions.
