Having honed their technology for sub-threshold transistor-based ARM Cortex-M series processors, the Wizzards of Tiny-Amps at Ambiq Micro have come up with an IoT device with a power consumption so low it has the potential to double the battery life in wearable devices. In numbers: 10 µA/MHz goes into an ARM Cortex-M processor. Code name: Apollo2.

Ambiq’s Apollo2 has up to 1 Mbyte of flash memory and 256 kBytes of RAM to accommodate radio and sensor overhead while still leaving plenty of space for application code. Serial master and UART ports are available for communicating with radios and sensors including accelerometers, gyroscopes, and magnetometers.

Apollo2 to Houston, we have on board:
  • 14-bit analogue-to-digital converters
  • Digital microphone interface with pulse density modulation (PDM) for voice application
  • Voltage comparator
  • Temperature sensor
  • I2C/SPI for communication with sensors, radios, co-processor and other peripherals

All systems are ARM-ed and Go, and Battery Status looks a-okay for extended period.
