The EDMS105N MCU is a power-optimized 32-bit device that can deliver 24MHz operation. It employs an ARM Cortex-M0 processing core, and is offered as the lowest power consuming Cortex-M0-based MCU to be commercially available, drawing only 18µA/MHz while in active mode.

The device has an array of different sleep states, the lowest of which will take its current draw down to just 340nA (with its real-time clock running and 8kB SRAM retention). A multitude of different interfaces are embedded into the MCU (UART, I2C and I2S, plus numerous GPIOs), as well as data conversion and voltage regulation elements.

The product, says the company, shows the company’s scope is now going beyond energy harvesting alone.

“The release of our EDMS105N MCU is the culmination of many years of in-depth research and development work, and we are excited to see how extensive an impact it will have on the IoT sector in the years ahead,” says CEO and co-founder of e-peas, Geoffroy Gosset “This is the first of a series of announcements that are going to take us towards being a one-stop shop for all the key IC components needed for extremely low power systems.”

The EDMS105N, says the company, is perfect for sensing applications that operate for extended period of time in standby mode. Applications include smart home, smart building, smart sensor, industrial monitoring, asset tracking, and e-heath/medical.
