Applied sensor technology is now used in a variety of electronic products. This technology is essential to achieving high-performance “intelligent” functions. In recent years, applied sensor technology has gained increasing popularity from an eco-friendly standpoint for deducing power consumption. By monitoring peripheral activities and providing fine-grained control of product operation, overall power consumption can be significantly reduced. The importance of such functionality continues to grow. Systems employing a variety of sensors require multichannel A/D converters and timer inputs in order to control the many sensors deployed. In addition, device control is essential, for example to operate motors linked to sensors.
Renesas’ RL78/G14 and R8C/3x Series of microcontrollers provide multiple inputs and outputs at low cost and are ideal for flexible product configurations. They combine multifunction timers, multichannel A/D converters, and low-power operation suitable for applied sensor applications.
