S1C17W15 (rev 1.00)
16-bit Single Chip Microcontroller
z Low power operation from 1.2V with a single alkaline or silver
oxide button battery.
z Low power consumption standby driving at HALT 0.5 μA (TBD) .
*super economy mode
z Built-in LCD Driver: 30 SEG x 8 COM (max.)
z Internal 4ch R/F converters enable to realize various sensing.
■ DESCRIPTIONS
The S1C17W15 is a 16-bit MCU that features low-voltage operation from 1.2 V even though the Flash memory is
included. The embedded high-efficiency DC-DC converter generates the constant-voltage to drive the IC with
lower power consumption than 4-bit MCUs. This IC includes a real-time clock, a stopwatch, an LCD driver, 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 LCD display and timers.
