Epson launches first product S1C17W22 from its new ultra-low power 16-bit Flash microcontroller family

Ideal for low-capacity battery driven applications

(PresseBox) (Munich, ) Seiko Epson Corporation ("Epson", TSE: 6724) has announced that it has developed and begun shipping samples of the S1C17W22, a 16-bit flash microcontroller capable of driving 1344-dot matrix high-resolution displays by achieving low power consumption of 4-bit flash microcontrollers.

Recently, there is a growing demand for flash memory microcontrollers with ultra-low power consumption for applications like high-performance watches, remote controls, health care devices, security tokens or small portable electronic devices that are powered by coin cell batteries. Also functions for those applications where measuring temperature, humidity and step counting is requested are increasing to achieve higher performance and create add on values for customers. In order to achieve higher performance and more vivid images, the S1C17W22 features a 1344-dot matrix LCD driver and offers a built-in 64kB flash ROM to store display data. Beside that the new 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 - 80% of the power used by previous configurations [1], making the S1C17W22 ideal for applications that run on small coin cell batteries.

To achieve such ultra-low power consumption values, S1C17W22 offers system power efficiency-boosting algorithms and more power modes than previous configurations [1]. Standby energy consumption is just 0.15 µA at 3 V. S1C17W22 also achieves low power current of just 0.3 µA in 32 kHz halt mode and 4 µA in 32 kHz run mode [2] by an internal DC/DC step-down converter, which optimizes the microcontrollers internal operating voltage.
