Overview

The EFM32ZG110F32 is a 32-bit microcontroller based on the ARM Cortex-M0+ core, designed specifically for ultra-low power applications. It operates at speeds up to 24MHz and includes 32KB of Flash and 4KB of RAM, making it suitable for energy-sensitive embedded tasks. Part of the Silicon Labs Zero Gecko family, it features advanced power management and an autonomous Peripheral Reflex System (PRS).

Why Choose This Part

This MCU offers industry-leading power efficiency with a run current of 114 uA/MHz and a shutdown mode consuming only 0.035 uA. The inclusion of a 4-channel DMA and a hardware AES encryption engine offloads the CPU, while the 1.98V to 3.8V operating range is well-suited for various battery chemistries.

Applications

Battery-Powered Sensors
Ideal for remote environmental or industrial sensors where long battery life is critical due to the 0.5 uA standby current.
Smart Energy Meters
Utilizes the built-in RTC and low-power modes to perform periodic metering tasks with minimal energy consumption.
Handheld Medical Devices
Integrates 12-bit ADC and DAC peripherals for precision analog measurements in portable diagnostic equipment.
Building Automation
Supports UART, SPI, and I2C interfaces for communicating with wireless modules and local sensors in smart home hubs.
