SiLEFM32HG322F64G-C-QFP48
Overview
The EFM32HG322F64G-C-QFP48 is an ARM Cortex-M0+ microcontroller from the Happy Gecko family, optimized for ultra-low power consumption and USB applications. It operates at up to 25MHz and integrates 64KB of Flash with 8KB of RAM in a 48-TQFP package. This device is specifically designed for battery-operated systems that require energy-efficient processing and a compact form factor.
Why Choose This Part
This MCU features a highly efficient energy management system with current consumption as low as 127 uA/MHz in run mode and 0.6 uA in standby. The inclusion of a 128-bit hardware AES engine and a 4-channel 12-bit ADC provides advanced functionality without a significant power penalty. Its Peripheral Reflex System allows peripherals to communicate without CPU intervention, further reducing power consumption.
Applications
Key Specifications
Getting Started
Developers can use Silicon Labs Simplicity Studio IDE, which provides the Gecko SDK and energy profiling tools. For hardware evaluation, the EFM32 Happy Gecko Starter Kit (EFM32HG-STK3400) is the primary development platform. The chip supports standard ARM SWD debugging for use with J-Link probes.
