Cortex-M4 based MCUs feature ultra-low power

The Apollo family of 32-bit Cortex-M4F microcontrollers consume an extremely low 30µA/MHz when executing instructions from flash and feature average sleep mode currents as low as 100 nA. The chips use sub-threshold voltage technology for power reduction. They have a floating point unit and operate at up to 24 MHz from a single 1.8 to 3.8 V supply.

The chips have up to 512 Kbytes of flash and 64 Kbytes of RAM, along with a 10-bit, 13-channel 1 Ms/s A/D converter and a temperature sensor with ±2ºC accuracy. Two packaging options are available – a 64-pin, 4.5 x 4.5 mm BGA package and a 2.4 x 2.77 mm 42-pin CSP. A data sheet or part number was not available. Product available Q1 with prices from $1.50 ea/10,000.
