IOT Roadmap - Adoption & Standardization

Editor's Notes

• #11: 26 billion devices Cortex-M0+ parts will consume well under 1 µA in Sleep Mode Minimize the number of I/O pins Minimize the number of internal peripherals Select Cortex-M0+ family or equivalent components Verify that a low-power timer is included on the parts Make sure that a DMA (Direct Memory Access) controller is included  newer FRAM (Ferroelectric RAM) chips go as low as 200 μA (1 MHz) Aluminum capacitors should be avoided due to their high leakage current values Leakage current can be decreased by increasing the voltage rating on the capacitor Minimize bulk capacitance on the voltage regulator outputs Minimize the number of capacitors since each capacitor will have leakage they can add up quickly. Select the largest value pull-up resistors to minimize their leakage current Avoid voltage divider circuits Minimize switching frequencies in regulators Using low-power timers for wake-up Writing the software to be event driven Using the lowest power energy modes Utilizing the DMA controller Autonomous peripherals https://www.digikey.com/en/articles/techzone/2017/feb/minimizing-iot-sensor-node-power-consumption AWS Greengrass Azure IOT Google IOT Bluetooth 5.0 introduces a new capability to increase the bandwidth to 2 Mbps.
