EFR32FG12P432F1024GM48-CR

RF Transceiver ICS Overview

The EFR32FG12P432F1024GM48-CR is a Flex Gecko System-on-Chip (SoC) from Silicon Labs, designed for proprietary wireless applications. It integrates an ARM Cortex-M4 core operating at up to 40 MHz with 1 MB of flash memory and 256 kB of RAM. The device features a 2.4 GHz radio supporting data rates up to 2 Mbps, delivering 19 dBm output power and -91.3 dBm sensitivity. It operates on a supply voltage range of 1.8 V to 3.8 V, consuming 8.5 mA during transmission and 10.8 mA during reception. The component is housed in a QFN-48 package.

RF Transceiver ICS Feature Summary

• Integrates an ARM Cortex-M4 processor with substantial non-volatile memory and static random-access memory for complex application execution.
• Features a high-performance 2.4 GHz transceiver optimized for proprietary protocols with strong transmit power and receiver sensitivity.
• Supports standard serial communication interfaces including I2C, SPI, and UART for peripheral connectivity.

RF Transceiver ICS Applications

• Proprietary wireless sensor networks
• Industrial monitoring systems
• Smart home actuators

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'CR' against the manufacturer's current datasheet to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact pinout and temperature grade specified in the official documentation. Cross-reference the Mouser number 634-FG12P432GM48-CR for accurate sourcing details.

RF Transceiver ICS Selection Notes

Select this model when a 2.4 GHz frequency band is required for proprietary communication rather than standard Bluetooth or Wi-Fi. The 19 dBm output power supports extended range applications. The QFN-48 package offers a compact footprint suitable for space-constrained designs requiring 31 general-purpose input/output pins.

RF Transceiver ICS Part Context

This component belongs to the EFR32FG12 Flex Gecko family, which targets sub-GHz and 2.4 GHz proprietary wireless markets. It shares architectural similarities with other FG12 variants but differs in radio frequency specifications and memory configuration. The series is designed for low-power, cost-sensitive embedded wireless applications.

RF Transceiver ICS Replacement Considerations

The EFR32FG12P432F1024GM48-C is a compatible variant differing primarily in packaging format. Verify interface compatibility and thermal performance when substituting between tray and reel configurations.
