The number of functions provided in electronic equipment has been growing in recent years, and program sizes are increasing as the amount of information is displayed. Meanwhile, equipment manufacturers need either maintain or further shrink the size of their products, making it essential to reduce the number of parts and save board space.
To solve these problems, Epson developed the S1C31W73 — a single-chip microcontroller (MCU) that has 384 KB of built-in Flash memory and a liquid crystal driver that can directly drive a display of up to 2560 dots. By combining Epson’s microcontroller display driver technology with the Arm Cortex-M0+ processor, the company seeks to help customers increase the functionality and performance of their products while also reducing their development burden.
The MCU offers a wide range of built-in peripherals, including a USB 2.0 full-speed device controller, real-time clock (RTC), various timers, an A/D converter and a temperature sensor. The low current consumption of 1.2 µA in RTC mode and a driving current of 150 µA/MHz-make it suitable for extending the battery life of wearable products and for office equipment that can communicate with PCs over USB. The product can also be used in industrial equipment and measuring instruments because it operates at temperatures up to 105°C and at voltages between 1.8 and 5.5 V.
