Smoke Detector
详情介绍
Overview
Renesas’ RL78/I1D and RL78/G12, G13, G14 integrate on-chip the peripheral functions necessary for use in smoke detector design, making it possible to reduce the overall product size. Low-voltage operation contributes to extended battery life, which is essential for detectors that must operate over extended periods of time.
