The S1C17W23 features a 1344-dot matrix LCD driver and offer a built-in 96kB flash ROM to store display data. Beside that the new 16-bit microcontroller can still operate at 1.2V and offers an integrated hardware Real-Time Clock (RTC) to reduce software and hardware development. By incorporating these functions on a single chip, Epson has developed a microcontroller that consumes only 70-80% of the power used by previous configurations, making the S1C17W23 suitable for applications that run on small coin cell batteries.

The chip offers system power efficiency-boosting algorithms and more power modes than previous configurations. Standby energy consumption is just 0.15 µA at 3V. The IC also only draws 0.3 µA in 32 kHz halt mode and 4 µA in 32 kHz run mode (250µA in 1MHz run mode).
