The S1C17W23 features a 1344-dot matrix LCD driver and has a built-in 96 kB flash ROM to store display data. It can operate at 1.2V and has an integrated hardware Real-Time Clock (RTC) to reduce software and hardware development. Epson's microcontroller onsumes 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 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 (250 µA in 1MHz run mode).
