Overview
The EFR32MG27C230F768IM32-BR is a Bluetooth and Zigbee System-on-Chip from Silicon Labs, operating at 2.4 GHz with an ARM Cortex-M33 core running at 76.8 MHz. It features 768 kB of flash memory and 64 kB of RAM. The radio supports up to 6 dBm output power and -96.3 dBm sensitivity. Supply voltage ranges from 1.71 V to 3.8 V, with receive current of 3.6 mA and transmit current of 11.3 mA. It includes 12/16-bit ADC, I2C, SPI, UART interfaces, and operates between -40°C and +125°C in a QFN-32 package.
Feature Summary
- Integrates a high-performance 32-bit ARM Cortex-M33 processor with DSP instructions for efficient signal processing.
- Supports multiprotocol wireless communication including Bluetooth v5.0 and Zigbee standards.
- Features an integrated DCDC boost converter enabling operation down to 0.8 Volts for single-cell battery applications.
Applications
- Smart Home devices
- Lighting and Building Automation systems
- Zigbee Green Power end-devices
Procurement Notes
Verify the specific suffix BR indicates reel packaging configuration against official Silicon Labs documentation. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the QFN-32 package dimensions match the target PCB footprint design constraints.
Selection Notes
Select this component when low power consumption and small form factor are critical for IoT end-devices. The integrated DCDC boost allows use of single-cell alkaline or button cells. Choose this model over variants with different memory sizes or pin counts based on application storage and I/O requirements.
Part Context
This part belongs to the EFR32MG27 Series 2 family of multiprotocol wireless SoCs. It is designed specifically for low-power, small-form-factor applications. The series expands the Zigbee portfolio while maintaining compatibility with Bluetooth protocols for versatile connectivity solutions.
Replacement Considerations
EFR32BG27C230F768IM32-BR shares identical physical specifications but lacks Zigbee support. EFR32MG27C230F768IM40-BR offers the same electrical performance in a 40-QFN package. Verify protocol stack requirements before substituting.
