The S1C63616 is a microcomputer which has a 4-bit CPU S1C63000 as the core CPU, ROM (16,384 words
×
13 bits), RAM (2,048 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 1,280 dots of LCD
panel, and an R/f converter that can measure temperature and humidity using sensors such as a thermistor.
The S1C63616 features low current consumption, this makes it suitable for battery driven clocks and
watches with temperature and humidity measurement functions.
