EZR32WG Description

Short technical summary and product information.

The EZR32WG330F256R69G from Silicon Labs is part of the EZR32WG Wireless MCU family, built around an ARM Cortex-M4 CPU. This device integrates a high-performance sub-GHz RF transceiver with an energy-efficient 32-bit MCU, delivering a flexible solution for proprietary wireless applications.

 

Key features include up to 48 MHz operation, 256 kB of Flash memory, and 32 kB of RAM. The integrated RF transceiver provides a receive sensitivity of -133 dBm and an output power of up to +20 dBm. It supports various modulations including GFSK, 4GFSK, GMSK, and OOK, with data rates from 100 bps to 1 Mbps.

 

Designed for ultra-low power consumption, the EZR32WG330F256R69G features efficient standby and sleep modes with fast wake-up times. It includes a rich set of peripherals such as a 12-bit ADC, 12-bit DAC, multiple communication interfaces (USB, UART, SPI, I2C), and an AES accelerator. These capabilities make it ideal for battery-powered applications in smart metering, health and fitness, consumer electronics, alarm systems, and building automation.

 

This component is noted as End of Life (EOL) and Last Time Buy (LTB). A recommended replacement is the EZR32WG330F256R68G.
