Silicon Labs EZR32 wireless MCUs deliver an ARM Cortex-M4 or Cortex-M3 microcontroller (MCU) combined with a sub-GHz RF transceiver.
The combination of a low energy wireless solution integrated into an energy efficient 32-bit MCU is ideal for battery powered applications. The EZR32 wireless MCUs are pin compatible devices that scale with 64/128/256kB of flash and support the EZRadio or EZRadioPRO transceivers.The EZR32 series also features a low energy sensor interface (LESENSE), and an AES accelerator with 128/256-bit keys.
