The sensor application is a technology applied to various products including electric appliances, a technology which is essential for product performance and intelligence. Recently, it has also been paid attention to from an ecology point of view as an indispensable technology that contributes to low power consumption by precisely controlling the behavior of products via sensing the surrounding conditions.

Multi-channel communication functions (serial interface), A/D converters and timer inputs are required in those systems that use and control many different sensors. In addition, device controlling functions such as motor control are also essential.

Renesas has a lineup of microcomputers that are suitable for achieving flexible environmental sensor product configurations.
