Solution Requirement Requirement Explanation
1. Autonomous, energy-efficient sensor systems By using an autonomous sensor system, the power-hungry core and other unnecessary peripherals can remain in Deep Sleep mode.
2. Individually configurable sensor inputs/outputs, thresholds, and configurations for each sensor Because the inputs/outputs are each individually configurable for their assigned sensor, even various aspects of the sensor system itself remain asleep while others take measurements.
3. Low-power, configurable logic engine that wakes up the MCU only when it's absolutely required. With low-power, dedicated logic, almost endless variations in sensor thresholds and events can be handled without waking the core until it's required.
4. Low-power memory to lengthen times between CPU wake-ups Dedicated storage complements the low-power logic and allows multiple events to occur without waking the core or the rest of the chip. The same memory can improve sensor recalibration when necessary.
5. Low-power wireless Wireless Geckos offer some of the most energy-efficient Bluetooth® Low Energy (BLE), ZigBee®, Thread, and proprietary wireless in the market.
