EZR32LG230F128R55G-B0R

RF Transceiver ICS Overview

The EZR32LG230F128R55G-B0R is a wireless microcontroller from the Leopard Gecko series, integrating an ARM Cortex-M3 core with an 802.15.4-compliant EZRadio transceiver. It features 128 kB of flash memory and 32 kB of RAM, operating at a maximum clock frequency of 48 MHz. The device supports frequencies from 142 MHz to 1.05 GHz and includes a 12-bit ADC with eight channels. Powered by a voltage range of 1.98 V to 3.8 V, it offers 41 I/O pins and interfaces including I2C, SPI, and UART within a QFN-64 package.

RF Transceiver ICS Feature Summary

• Integrates an ARM Cortex-M3 processor with an 802.15.4 compliant RF transceiver for low-power wireless connectivity.
• Supports global sub-GHz ISM band operation via the EZRadio transceiver for versatile regional compliance.
• Includes high-resolution analog peripherals such as a 12-bit ADC and multiple timers for sensor interfacing.

RF Transceiver ICS Applications

• Smart home automation systems
• Building automation controllers
• Wireless sensor networks

RF Transceiver ICS Procurement Notes

Verify the specific suffix R55G against the official datasheet to confirm regulatory certifications and frequency band configurations. Ensure the QFN-64 package dimensions match the target PCB footprint. Confirm that the supply chain source provides genuine Silicon Labs components to avoid counterfeit risks in critical IoT deployments.

RF Transceiver ICS Selection Notes

Select this component when both processing power and sub-GHz wireless capabilities are required in a single chip. The Cortex-M3 core suits applications needing more complex logic than M0+ variants. Consider the 128 kB memory size for firmware requirements. Evaluate the 41 available I/O pins against peripheral needs before choosing alternative pin counts.

RF Transceiver ICS Part Context

This part belongs to the EZR32LG230 Leopard Gecko family, designed for energy-efficient wireless applications. It bridges the gap between simple MCUs and complex SoCs by combining a standard ARM core with integrated RF functionality. The series targets markets requiring robust, long-range communication with minimal external components.
