The S1C17W22 features a 1344-dot matrix LCD driver and offers a built-in 64kB flash ROM to store display data. Beside that the 16-bit microcontroller family 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 to 80% of the power used by previous configurations, making the S1C17W22 suitable for applications that run on small coin cell batteries.

Standby energy consumption is just 0.15µA at 3V while the S1C17W22 draws only 0.3µA in 32kHz halt mode and 4µA in 32 kHz run mode by an internal DC/DC step-down converter, which optimizes the microcontrollers internal operating voltage. It consumes 250µA in 1MHz run mode. Other features include various timer circuits, serial interface, UART and I²C support, a sound generator and universal port multiplexers for board layout flexibility. The IC also delivers an infrared remote control output. The chip is available as a bare die or in a TQFP15-128 package.
