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.
