Vitality-harvesting specialist E-peas has introduced it’s branching out into ultra-low-power microcontroller elements — unveiling “the bottom energy consuming Cortex-M0 microcontroller ever commercialized,” the corporate claims.
“E-peas has come a good distance since its creation. With our scope now going past power harvesting alone, we will make an excellent greater contribution to the worldwide IoT edge gadgets progress,” claims E-peas chief govt and co-founder Geoffroy Gosset. “The discharge of our EDMS105N MCU is the fruits of a few years of in-depth analysis and improvement work, and we’re excited to see how in depth an impression it should have on the IoT sector within the years forward.”

Constructed round Arm’s Cortex-M0 core IP, the 32-bit EDMS105N microcontroller can run as much as 24MHz at a claimed 18µA/MHz in energetic mode — dropping down to only 340nA in its lowest-draw sleep mode, which retains the real-time clock operating and retains information in a single 8kB financial institution of static RAM (SRAM).
Designed to be used with a 1.8-3.3V provide voltage, the half consists of 32kB of SRAM and 256kB of single-cycle flash reminiscence, an eight-channel direct reminiscence entry (DMA) controller, Single Wire Debug (SWD), one UART and a further debug UART, two SPI, two I2C, and two I2S buses, as much as 48 general-purpose enter/outputs (GPIOs), 4 32-bit timers with two evaluate/seize channels, one real-time clock, and a 32-bit watchdog.
Different options of the half embody a single 12-bit analog to digital converter (ADC) with eight channels, a rail-to-rail analog comparator with VDD scaler, and an AES acceleration module supporting ECB, CBC, and CTR modes plus a {hardware} true random quantity generator (TRNG) based mostly on clock drift. All that is packaged in a QFN48 measuring 6mm (round 0.24″) on a aspect.

Whereas asserting the brand new half on the Client Electronics Present (CES), E-peas additionally unveiled an instance utility: An autonomous surveillance system, pushed by the brand new microcontroller and powered wholly from harvested power. On the similar time, the corporate additionally showcased a brand new antenna design developed in partnership with Ignion — and the primary, the corporate claimed, to be optimized for power harvesting functions.
E-peas didn’t reveal availability or pricing on the brand new microcontroller, however promised it will be sampling “quickly.” events, in the meantime, can learn extra on the official product web page.
