Ambiq Micro’s Apollo 2 sub-threshold-tech MCU – in distribution

January 18, 2017 // By Graham Prophet
Distribution company Fujitsu Electronics Europe (FEEU) has Ambiq Micro’s Apollo 2 Platform for the European market. The new ultra-low-power MCU claims ‘breakthrough’ power consumption of around 10 µA/MHz, allowing wearables and IoT devices to double battery life. General availability is planned for the second half of 2017.

Ambiq Micro’s technology uses sub-threshold switching – distinguishing binary values at voltages below what, in conventional CMOS, would be the transistor’s on-state. Ambiq says its platform’s low processing power consumption and large memory size give designers the ability to develop products at power levels that would otherwise be out or reach. The second-generation Apollo 2’s complete set of peripherals includes:

- High-precision 14-bit analogue-to-digital converters (ADC)

- Digital microphone interface with pulse density modulation (PDM) for voice applications

- Voltage comparator

- Temperature sensor

- I ²C/SPI for communication with sensors, radios, co-processor and other peripherals

- UART for communication with peripherals and legacy devices

- Integrated high efficient buck-converters
