Overview
Description
This reference design offers a multiwavelength smoke detector for commercial buildings. The board consists only of the RL78/G22 microcontroller, an analog front-end (AFE), LEDs, photodiodes, and several external components. Additionally, by utilizing the SNOOZE mode sequencer (SMS) of the RL78/G22, it enables ultra-low power consumption and high-precision smoke detection, allowing for a compact multi-wavelength smoke detector design.
Features
- Compact, low-power, high-performance MCU
- Integrated low-power AFE for photoelectric smoke detection that contains all necessary peripherals
- Minimal external components, achieving the lowest BOM and a smaller size
Applications
- Commercial and household smoke detector
