DESCRIPTION
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.
