EZR32LG Wireless MCUs
EZR32LG330 Data Sheet
EZR32LG330 Wireless MCU family with ARM Cortex-M3 CPU,
USB, and sub-GHz Radio
The EZR32LG Wireless MCUs are the latest in Silicon Labs family of wireless MCUs de-
livering 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 EZR32LG family provides designers the ultimate in flexibility
with a family of pin-compatible devices that scale with 64/128/256 kB of flash and sup-
port 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, com-
bined with the low transmit and receive power consumption of the sub-GHz radio, result
in a solution 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
KEY FEATURES
• Silicon Labs’ first 32-bit Wireless MCUs
• Based on ARM Cortex M3 (LG) and M4
(WG) CPU cores with 256 kB of flash and
32 kB RAM
• Best-in-class RF performance with EZradio
and EZRadioPro transceivers
• Ultra-low power wireless MCU
• Low transmit and receive currents
• Ultra-low power standby and sleep
modes
• Fast wake-up time
• Low Energy sensor interface (LESENSE)
• Rich set of peripherals including 12-bit ADC
and DAC, multiple communication
interfaces (USB, UART, SPI, I2C), multiple
GPIO and timers
• AES Accelerator with 128/256-bit keys
