SiLEFM32HG210F64G-C-QFN32
Overview
The EFM32HG210F64G-C-QFN32 is a 32-bit ARM Cortex-M0+ microcontroller from the Silicon Labs Happy Gecko family, optimized for ultra-low power consumption and energy efficiency. It features 64KB of Flash, 8KB of RAM, and runs at speeds up to 25MHz while maintaining a very low active current of 127uA/MHz. This MCU is designed to extend battery life in portable applications through advanced energy management modes and a flexible Peripheral Reflex System.
Why Choose This Part
The primary advantage is the ultra-low power profile, featuring a shutdown current as low as 0.02uA and a fast wake-up time. It includes a 6-channel Peripheral Reflex System (PRS) that allows peripherals to communicate without CPU intervention, further reducing active-mode power cycles. The inclusion of hardware AES-128 and a 4-channel 12-bit ADC provides a robust feature set for secure data acquisition in a small 6x6mm package.
Applications
Key Specifications
Getting Started
Engineers can begin development using the Simplicity Studio IDE, which provides power profiling tools to optimize energy consumption. Hardware evaluation is typically performed using Silicon Labs Starter Kits (STK) which include an on-board J-Link debugger and Advanced Energy Monitoring. The part supports standard ARM toolchains including GCC, Keil MDK, and IAR Embedded Workbench.
