IoT module sips power in sleep mode
30 January 2019, Telecoms, Datacoms, Wireless, IoT
Norwegian Internet of Things (IoT) developer, Nanopower, has developed an innovative way to reduce the power consumption of Nordic Semiconductor’s nRF52832 SoC to just 10 nA in sleep mode, and waking up the chip on a predetermined schedule or based on sensor threshold values.
Nanopower’s nP-BLE52 module employs a proprietary power management IC, integrated alongside Nordic’s nRF52832 system-on-chip (SoC) in a system-in-package (SiP). By reducing the SiP’s power consumption to such low levels, the module is ideal for IoT applications where battery life is critical by potentially increasing cell lifespan tenfold.
In active mode, the nRF52832 SoC runs normally. The SoC has been engineered to minimise power consumption with features such as the 2,4 GHz radio’s 5,5 mA peak Rx/Tx currents and a fully automatic power management system. Once the Nordic SoC has completed its tasks, it instructs the nP-BLE52 to put it to sleep and wake it up again at the pre-set time.
The nP-BLE52 then stores the SoC’s state variables and waits until it needs to be powered up again. On wake-up, the device uploads the previous state variables, allowing the SoC to be restored to the same operational state as before the power was cut. The SoC’s startup is much more rapid than if it was activated from a non-powered mode.
The nP-BLE52 module also features a low-power MCU which can be set to handle external sensors and actuators when the Nordic chip is switched off. In this state, the module still monitors sensors and buffer readings and can trigger wake-ups if these readings are above predetermined thresholds, while consuming less than 1 μA. The nP-BLE52 also integrates an embedded inertial measurement unit (IMU).
The module’s power management is controlled through a simple API, whereby the user can predetermine the duration of the Nordic SoC’s sleep mode, set the wake-up time and date parameters, and select pins for other on/off triggers.
