The EDMS105N general purposes microcontroller is based on the ARM Cortex-M0 32-bit architecture and presents an extremely low power consumption, both in active and standby mode. This makes it perfectly suited for sensing applications that operate for extended period of time in standby mode while still requiring processing capabilities. It is packed with multiple peripherals for communication, timing, sensing or security purposes along with memories, oscillators, integrated power regulators and an intelligent multi-mode power management unit. This extremely low-power, highly-integrated microcontroller will turn any sensing edge devices into true install and forget systems.

– 32-bit ARM Cortex-M0, 24 MHz operating frequency
