EFM32HG210 in Silicon Labs EFR32 / EFM32 Family
The EFM32HG210 series, part of the Silicon Labs Happy Gecko family, is an ultra-low-power 32-bit microcontroller line built on the ARM Cortex-M0+ core. These MCUs are designed specifically for battery-operated applications that require high performance and low energy consumption. They integrate advanced power management, a highly efficient peripheral set, and a crystal-less USB 2.0 interface, making them ideal for space-constrained and energy-sensitive embedded designs requiring minimal external components.
Variants within the EFM32HG210 sub-family are primarily distinguished by their flash memory capacity and SRAM size, typically ranging from 32KB to 64KB of flash. They also vary in package configuration, offering different pin counts to accommodate various I/O requirements. While the core processing architecture and USB functionality remain consistent, individual part numbers may specify different temperature ratings suited for commercial or industrial environments.
