SiLEFM32HG110F64G-C-QFN24
Overview
The EFM32HG110F64G-C-QFN24 is a 32-bit ARM Cortex-M0+ microcontroller from the Happy Gecko family, optimized for ultra-low power consumption and USB-less connectivity applications. It operates at up to 25 MHz with 64 kB of Flash and 8 kB of RAM, drawing as little as 127 microamps per MHz in active mode. This MCU is designed for energy-sensitive applications that require efficient processing and advanced peripheral autonomy.
Why Choose This Part
The Happy Gecko family stands out for its Peripheral Reflex System (PRS), which allows peripherals to communicate directly without CPU intervention, significantly reducing power consumption. It features a hardware AES engine for 128-bit encryption in just 54 cycles and maintains extremely low leakage in deep sleep modes. The 24-pin QFN package provides a compact 5x5mm footprint suitable for space-constrained designs.
Applications
Getting Started
Start development using the Silicon Labs Simplicity Studio IDE, which includes the Energy Profiler for real-time power debugging. Hardware evaluation can be performed using the EFM32 Happy Gecko Starter Kit (EFM32HG-STK3400). Connect via the 2-pin Serial Wire Debug (SWD) interface using any standard J-Link debugger.
