Epson Releases New 16-Bit RISC, Starts Production of Flash Microcontroller with LCD Driver

The S1C17701 is a single-chip microcontroller featuring on-chip Flash ROM and a high-resolution dot matrix LCD driver. With 64 KB of Flash ROM, the product is ideal for software development and evaluation activities.

Epson has utilized the low power consumption technology developed for its watch applications to achieve low current consumption (typically 2.5 µA during standby mode) and enable high-speed operation (8.2 MHz) with low operation voltage (1.8 V). In most ca ses, this product will allow customers currently using 8-bit microcontrollers to enjoy higher performance with the same power consumption. In addition, it will enable customers already using 16-bit microcontrollers to benefit from longer battery life as a result of low operating voltage.

Epson plans to continue its efforts to respond to customer demands in this area by expanding its device lineup based on the following core technologies--a low leak process to drastically cut current consumption during standby mode, an algorithm which sign ificantly improves system power efficiency, and analog circuits that are optimally designed for low power consumption.
