EFR32MG21A020F768IM32

Silicon Labs

EFR32MG21A020F768IM32 is a Silicon Labs multiprotocol wireless SoC for Zigbee, Thread and Bluetooth — 80 MHz Arm Cortex-M33 with 768 KB Flash and 64 KB RAM in 4x4 mm QFN-32, the silicon inside the most popular Home Assistant Zigbee coordinators. The A020 variant integrates a +20 dBm power amplifier for long-range mesh links; -104.3 dBm sensitivity at 250 kbps O-QPSK; Matter-ready with Secure Vault Base cryptography. Selection advice: the A020 (+20 dBm) suits coordinator and router roles — for battery end-devices the A010 (+10 dBm) draws less; the 768 KB Flash fits full Zigbee 3.0 plus OTA — the 512 KB F512 variant costs less for fixed-function nodes. This is the reference chip for Zigbee2MQTT coordinators — if your product is a Zigbee gateway, this is the default choice. Parameters verified against Silicon Labs documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SELECTION GUIDANCE

EFR32MG21A020F768IM32 selection guidance

EFR32MG21A020F768IM32 is a Zigbee/Thread SoC from Silicon Labs, orderable in the QFN-32 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.

When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

COMMON QUESTIONS

EFR32MG21A020F768IM32 FAQ

What do the suffixes in EFR32MG21A020F768IM32 mean?

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. EFR32MG21A020F768IM32 names the QFN-32 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.

What is the difference between package and packing for EFR32MG21A020F768IM32?

The package (QFN-32) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.

Can you provide traceability documents for EFR32MG21A020F768IM32?

Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.

How do I request a quotation for EFR32MG21A020F768IM32?

Add EFR32MG21A020F768IM32 to your RFQ with the complete ordering code, the manufacturer (Silicon Labs), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
