What Makes the S1 Series Stand Out

Low voltage operation down to 1.6 V with extremely low power operation modes and fast wake-up times of the CPU core and the analog/digital peripherals make S1 Series MCUs uniquely suited for battery-operated sensing and control applications. Hardware acceleration through peripherals helps optimize CPU bandwidth and lower power consumption giving more flexibility to manage events and data transfers. This series includes security functions such as a true random number generator and AES cryptography, safety self-test functions, a capacitive touch interface, and a real-time clock. Reliable and trusted portable applications are a must for IoT applications and the S1 Series MCUs enable just that.


Typical End Applications

Data capture and environment sensing such as smoke, carbon monoxide, chemical/gas, pressure, humidity, light; small kitchen appliances; portable/hand-held products such as Point Of Sale terminals, scanners, activity monitors, and fitness trackers.
