e-peas showcases the latest low-power MCU and people counting applications at CES

The energy autonomy monitoring system exhibited by e-peas supports energy mobile phones to meet their power needs and can be used for applications such as people counting and facial recognition (accessing stored data to confirm personal identity).

At the heart of the e-peas demonstration will be the game-changing EDMS105N MCU.

The EDMS105N MCU is a power-optimized 32-bit device that can run at 24MHz. It relies on the ARM Cortex-M0 processing core, leveraging platforms and related tools that engineers are already familiar with.

This is the lowest power Cortex-M0 MCU on the market, consuming only 18µA/MHz in active mode. It has a range of different sleep states, the lowest of which consumes only 340nA (RTC and 8kB SRAM retention).

Embedded in the MCU are a variety of different interfaces (UART, I2C and I2S, as well as a large number of GPIOs), as well as data conversion and voltage regulation components.

“The release of our EDMS105N MCU is the culmination of many years of intensive R&D work, and we are excited to see how broadly it will impact the IoT space in the coming years,” said Geoffroy Gossethe, co-founder and CEO of e-peas. “This is the first in a series of announcements that will make us a one-stop shop for all the critical IC components needed for extremely low-power systems.”

The RF energy harvesting antenna developed by e-peas in collaboration with Ignion of Spain is ten times smaller than standard off-the-shelf components and can be used in any frequency band and any device form factor with the appropriate matching network design to harvest energy at all frequencies in the range (0.4GHz to 10.6GHz range). When integrated with the AEM30940, AEM30330 or AEM30300 RF Environment Energy Manager (AEM), the antenna can capture energy from a distance of up to 17 meters when using a 1W transmitting source and achieve an energy capture range of 31 meters when using a 3W source. Since the antenna is independent of direction, it can capture energy from any direction.
