What the EZR32HG220F32 does
The EZR32HG220Fxx is a wireless microcontroller family featuring an ARM Cortex-M0+ CPU and sub-GHz radio transceivers. These devices span 32 or 64 kB of flash memory paired with 8 kB of RAM, supporting EZRadio and EZRadioPro transceivers. Key specifications include a 142 to 1050 MHz frequency range, receive sensitivity down to -133 dBm, and a single power supply operating from 1.98 to 3.8 V. The family offers ultra-low power modes with 20 nA shutoff current and fast wake-up times. Engineers typically use these components for energy, gas, and water metering, alarm and security systems, health and fitness applications, building automation, and consumer electronics requiring low-power wireless connectivity.
