Epson’s new 16-bit microcontroller features small size and low power consumption equivalent to an 8-bit microcontroller, even with the 16MB address space.
The S1C17 family of original 16-bit MCUs integrate a wide variety of interfaces, allowing connection with multiple sensors and a wealth of peripheral circuits such as an EPD driver,LCD controller and driver supporting low to medium-level resolutions.
The S1C17 family microcontroller has RISC architecture to achieve high-speed operation and low power consumption, making it ideal for mobile devices.
The family includes a rich lineup of built-in Flash ROM products.
The high quality development environment and on-chip ICE function also contribute to shorten design turnaround time.
