DESCRIPTIONS
The S1C63709 is a microcomputer which consists of a high-performance 4-bit CPU S1C63000 as the core CPU, ROM
(12,288 words × 13 bits), RAM (2,048 words × 4 bits), serial interface, 2-channel motor driver, solar charging circuit, an
LCD driver that can drive a maximum 64 segments × 8 commons, sound generator and time base counters. The S1C63709
features low current consumption, this makes it suitable for solar-powered radio-controlled watches.
