EZR32HG 32-bit Wireless MCUs

The EZR32HG Wireless MCU family delivers a high performance, low-energy wireless solution integrated into a small form factor package. By combining a high performance sub-GHz RF transceiver with an energy efficient 32-bit MCU, the EZR32HG family provides designers the ultimate in flexibility with a family of pin-compatible devices that scale with 64/32 kB of flash and support Silicon Labs EZRadio® or EZRadioPRO® transceivers. The ultra-low power operating modes and fast wake-up times of the Silicon Labs energy friendly 32-bit MCUs, combined with the low transmit and receive power consumption of the sub-GHz radio, result in a solution optimized for battery powered applications.
