S1C17W03/W04 (rev1.0) 16-bit Single Chip Microcontroller Low voltage operation from 1.2 V with a single alkaline or silver oxide button battery. Ultra low standby power consumption (0.3 A during HALT state in super economy mode) Embedded A/D converter to support various sensing applications DESCRIPTIONS The S1C17W03/W04 is a 16-bit MCU that features low-voltage operation from 1.2 V even though Flash memory is in- cluded. The embedded high-efficiency DC-DC converter generates the constant-voltage to drive the IC with lower pow- er consumption than 4-bit MCUs. This IC includes a real-time clock, a stopwatch, an A/D converter, and a PWM timer capable of being used to generate drive waveforms for a motor driver as well as a high-performance 16-bit CPU. It is suitable for battery-driven applications that require an A/D conversion function and timers.
