Uniquely suited for simple battery-operated sensing applications that require low power operation modes and fast wake-up times, the S124 MCU Group has 128 KB of flash memory and 16 KB of SRAM. It includes a 14-bit A/D Converter, 12-bit D/A Converter, and a Capacitive Touch Sensing Unit, in addition to safety and security features.

WIRELESS MOTION DETECTOR

 

Wireless Motion Detector

Special operating modes enabling the analog interface to detect motion even while the CPU sleeps, and extensive analog, timing and control, connectivity, and safety and security features, make the S124 MCU Group ideal for battery-powered wireless motion detection applications requiring ultra-low power consumption.
