EFR32BG1B132F256GM32-B0R

RF Transceiver ICS Overview

The EFR32BG1B132F256GM32-B0R is a Blue Gecko RF System on Chip (SoC) manufactured by Silicon Labs. It integrates an ARM Cortex-M4 core with a 2.4 GHz Bluetooth transceiver, 256 kB of flash memory, and 32 kB of RAM. The device supports Bluetooth v4.0 protocols and operates within a supply voltage range of 1.85 V to 3.8 V. Key electrical specifications include a maximum output power of 3 dBm, a receiver sensitivity of -99.2 dBm, and a maximum data rate of 2 Mbps. It features serial interfaces including I²C, UART, and USART, along with 16 GPIOs. The component is housed in a 32-VFQFN package with an exposed pad and functions reliably across a temperature range of -40°C to 85°C.

RF Transceiver ICS Feature Summary

• Integrates an ARM Cortex-M4 processor with a 2.4 GHz Bluetooth radio for combined processing and communication capabilities.
• Supports multiple modulation schemes including GFSK, MSK, and DSSS for flexible protocol implementation.
• Provides extensive peripheral connectivity through I²C, UART, USART, and SPI interfaces alongside general-purpose input/output pins.

RF Transceiver ICS Applications

• Bluetooth Low Energy (BLE) sensor nodes
• Wireless home automation devices
• Personal health and fitness trackers
• Smart lock systems

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'B0R' against official Silicon Labs documentation to confirm tape-and-reel packaging and exact variant characteristics. Confirm that the Bluetooth version aligns with project requirements, as datasheets may reference v4.0 while marketing materials suggest broader compatibility. Ensure the operating voltage range matches the target system design before procurement.

RF Transceiver ICS Selection Notes

Select this component when a compact solution combining BLE connectivity and MCU processing is required. The 3 dBm output power suits short-range applications, while the low current consumption supports battery-operated designs. Consider the 32-pin QFN package for space-constrained PCB layouts. Verify that the 256 kB flash capacity meets firmware storage needs.

RF Transceiver ICS Part Context

This part belongs to the EFR32BG1 series, known as Blue Gecko SoCs designed for Bluetooth applications. It shares architectural similarities with other Mighty Gecko and Flex Gecko variants but differs in radio performance and feature sets. The BG1 series focuses on cost-effective BLE solutions compared to higher-performance models like the MG1 or FG1 series.
