EFR32MG13P732F512IM32-D

Overview

The EFR32MG13P732F512IM32-D is a Mighty Gecko System on Chip featuring an ARM Cortex-M4 core operating at 40 MHz. It integrates 512 kB of Flash memory and 64 kB of RAM within a QFN-32 package. The device supports Bluetooth v5.0 (BLE), Thread, and Zigbee protocols over the 2.4 GHz band. Key electrical parameters include a maximum output power of 19 dBm, a receive sensitivity of -91.5 dBm, and a maximum data rate of 2 Mbps. Operating voltage ranges from 1.8 V to 3.8 V, with current consumption specified at 10.3 mA during reception and 35.3 mA during transmission.

Feature Summary

• Supports multi-protocol wireless communication including Bluetooth v5.0, Thread, and Zigbee.
• Integrates a high-performance ARM Cortex-M4 microcontroller with substantial onboard memory.
• Features a rich peripheral set including I2C, SPI, UART, and ADC for sensor interfacing.

Applications

• Smart home lighting and control systems
• Wireless door locks and security sensors
• Industrial mesh networking nodes

Procurement Notes

Verify the specific suffix 'D' indicates the extended temperature range variant (-40°C to +125°C) as documented in official specifications. Confirm the QFN-32 package dimensions and exposed pad requirements against your PCB layout guidelines. Ensure compatibility with the intended wireless protocol stack before procurement.

Selection Notes

Select this component when a balance of moderate processing power and integrated RF performance is required for battery-operated devices. The 19 dBm output power suits applications needing reliable mesh network connectivity without excessive power drain. Consider the 32-pin footprint constraints and available GPIO count for peripheral integration.

Part Context

This part belongs to the Silicon Labs Mighty Gecko family, designed for low-power IoT applications. It shares architectural similarities with other MG13 variants but differs in memory size and package type. The IM32 designation specifically identifies the QFN-32 package configuration within the product line.

Replacement Considerations

Public confirmed substitute part numbers include EFR32MG13P732F512IM32-DR and EFR32MG13P732F512IM48-C. Verify pinout compatibility and firmware support when transitioning between package types or reel/tray packaging options.
