Ultra-low-power MCU for install-and-forget edge devices and sensor hubs

Mr. X is excited to share news of an innovative device from e-peas, the EDMS105N MCU, which is claimed to be the lowest-power Arm Cortex-M0-based device on the market.

The EDMS105N’s ultra-low power consumption is the result of some clever tweaks to the power management systems inside the chip, as well as a smart architecture with features such as inter-peripheral signalling for core-less peripheral communication. The result is active current of just 18 µA/MHz and 340 nA Deep Sleep current.

This means the EDMS105N can be used in install-and-forget sensor hub and edge processing applications – so little power is used that in many cases the application’s battery need never be replaced. This is ideal for smart sensor, smart industrial monitoring, smart home, asset tracking, smart building, and e-health/medical applications.

Key features include:

  • 24 MHz, 32-bit ARM Cortex-M0 MCU with up to 48 GPIOs
  • 1 MHz low-power mode for instantaneous power reduction
  • Built-in buck converters and LDOs

We recently visited e-peas booth at Embedded World to have a look at their power-harvesting innovation in person. Watch the full interview with Pierre here:

The EDMS105N is available in a QFN48 6 x 6 mm package. While a commercial evaluation board is not available, ipXchange is able to facilitate evaluation for select customers. A more detailed rundown of the EDMS105N’s specifications can be found in the board application form below.

Keep designing!
