EFR32ZG14P231F256GM32-B

Overview

The EFR32ZG14P231F256GM32-B is a Z-Wave 700 Modem System-on-Chip from Silicon Labs, designed for Z-Wave controllers and gateways. It features an ARM Cortex-M4 core operating at 39 MHz with 256 kB of program memory and 32 kB of RAM. The integrated sub-GHz radio supports frequencies including 868 MHz and 915 MHz, delivering up to 14 dBm output power and -98.8 dBm sensitivity. It operates within a voltage range of 1.8 V to 3.8 V, consuming 8.4 mA during reception and 35.3 mA during transmission.

Feature Summary

• Integrated sub-GHz radio optimized for Z-Wave protocol implementation
• High-performance 32-bit ARM Cortex-M4 processor core
• Low-power wireless system-on-chip architecture
• Differential radio interface for efficient connectivity

Applications

• Z-Wave controller devices
• Z-Wave gateway hardware
• Sub-GHz modem applications

Procurement Notes

Verify that the application design strictly adheres to the component's intended use as a modem SoC for controllers and gateways only. This part is not certified or suitable for use in Z-Wave end-devices. Ensure compliance with regional sub-GHz frequency regulations for the specific market deployment.

Selection Notes

Select this component when designing Z-Wave infrastructure nodes requiring dedicated modem functionality rather than end-device capabilities. It is appropriate for projects needing robust sub-GHz communication with moderate data rates. Consider the QFN32 package constraints and thermal requirements for the target enclosure design.

Part Context

This part belongs to the EFR32ZG14 family, which focuses on Z-Wave 700 series compliance. Unlike the FG14 or MG14 variants, the ZG14 series is specifically engineered for Z-Wave network management roles. It shares the same physical footprint and core architecture but differs in radio certification and protocol optimization for controller/gateway duties.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Silicon Labs lifecycle notices for potential obsolescence management or next-generation replacements.
