EZR32HG Wireless MCUs
EZR32HG320 Data Sheet
EZR32HG320 Wireless MCU family with ARM Cortex-M0+ CPU,
USB, and sub-GHz Radio
The EZR32HG Wireless MCUs are the latest in Silicon Labs family of wireless MCUs
delivering 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 ener-
gy 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 Sili-
con 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 solu-
tion optimized for battery powered applications.
32-Bit ARM Cortex wireless MCUs applications include the following:
• Energy, gas, water and smart metering
• Health and fitness applications
• Consumer electronics
• Alarm and security systems
• Building and home automation
