S1C63632
4-bit Single Chip Microcomputer
Original Architecture Core CPU
Low Current Consumption
High Speed Operation in Low Voltage
„ DESCRIPTION
The S1C63632 is a microcomputer which has a 4-bit CPU S1C63000 as the core CPU, ROM (31,744 words ×
13 bits), RAM (8,192 words × 4 bits), multiply-divide circuit, serial interface, watchdog timer, programmable
timer, time base counters (2 systems), a dot matrix LCD driver that can drive a maximum 1,536dots of LCD
panel, and an R/f converter that can measure temperature and humidity using sensors such as a thermistor.
The S1C63632 features low current consumption, this makes it suitable for battery driven clocks and watches
with temperature and humidity measurement functions.
