EFR32FG1V131F128GM32-C0R

RF Transceiver ICS Overview

The EFR32FG1V131F128GM32-C0R is a Sub-GHz Flex Gecko System-on-Chip integrating an ARM Cortex-M4 core with a radio transceiver. It features 128 kB of flash memory and 16 kB of RAM, operating within the 169 MHz to 915 MHz frequency range. The device supports data rates up to 2 Mbps and delivers a maximum output power of 19.5 dBm. It operates on a supply voltage of 1.85 V to 3.8 V, with receive current at 9.8 mA and transmit current ranging from 8.2 mA to 126.7 mA. Sensitivity reaches -92.5 dBm. Packaged in a 32-VFQFN exposed pad (5x5 mm), it functions between -40°C and +85°C.

RF Transceiver ICS Applications

• Smart metering and utility infrastructure
• Industrial wireless sensor networks
• Home automation and security systems
• Remote control devices

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'C0R' to confirm the reel packaging variant, as tape-and-reel availability differs from tray configurations. Ensure the design accommodates the 32-VFQFN package dimensions and thermal requirements. Confirm that the target application frequency falls within the supported 169-915 MHz range. Check for any recent product change notices regarding pinout or electrical characteristics updates.

RF Transceiver ICS Selection Notes

Select this component when Sub-GHz connectivity is required rather than 2.4 GHz. It is suitable for applications needing moderate range and low power consumption. Compare against EFR32FG1P series if higher output power is needed. Consider the EFR32FG1V series for general Sub-GHz needs. Evaluate memory requirements against the 128 kB flash limit. Ensure the host system can support the 1.85 V to 3.8 V supply range.

RF Transceiver ICS Part Context

This part belongs to the Silicon Labs Flex Gecko family, designed for cost-effective wireless IoT solutions. The FG1V variant specifically targets Sub-GHz frequencies, distinguishing it from the 2.4 GHz BG1V or MG1B series. It shares architectural similarities with other EFR32G1 chips but differs in radio front-end specifications and supported frequency bands.

RF Transceiver ICS Replacement Considerations

EFR32FG1V131F128GM32-B0 is a previous version with potential minor parameter differences. EFR32FG1V132F128GM32-C0 is a tray-packaged alternative. Verify pin compatibility and software library support before substitution.
