1. Proprietary products and applications

Introduction:

Silicon Labs' proprietary wireless devices provide high-performance wireless connectivity and ultra-low power 32-bit microcontroller options. With support for major frequency bands in the 142 to 1050 MHz range and 2.4 GHz, these devices can be used to develop many wireless communication systems.
Chip name conventions:

For proprietary products, there are many FG type chips which are classified with generations, packages, flash size, temperature grades, output power levels, and frequency bands. The general name convention is as follows:

As you can see from the name convention, the proprietary chips include four series such as FG1, FG12, FG13,and FG14. The chips are classified with P (Performance), B (Basic), and V (Value) performance grades. The chips are Tx/Rx type which include sub-G band, 2.4GHz band, and sub-G& 2.4GHz bands. The chips are classified with 2 temperature range as -40°-+85° and -40°-+125°. And there are many packages(QFN32, QFN40, QFN48, QFN68, and BGA125) to select.
Applications:

Meters(Gas, water, electricity), Door locks, Electronic lables, Wireless toys, Wireless ranch, Remote controllers, etc.

2. Zigbee/Thread products and applications

Introduction:

Silicon Labs is the vendor of choice for OEMs developing Zigbee networking into their products. The Silicon Labs Zigbee platform is the most integrated, complete and feature rich Zigbee solution available — a family of Wireless SoCs, based on Arm® Cortex® processor and 2.4 GHz transceiver, together with the most reliable, scalable and advanced Zigbee software and supported by best-in-class development tools.
Chip name conventions:

For Zigbee/Thread products, there are also many MG type chips which are classified with generations, packages, flash size, temperature grades, output power levels, and frequency bands. The general name convention is as follows:

As you can see from the name convention, the Zigbee/Thread chips include 2 variants such as MG12 and MG13 for EFR32MG1x series 1 chips, and 2 variants as MG21 and MG22 for EFR32MG2x series 2 chips. The Zigbee/Thread chips only have P performance grade. The chips are Tx/Rx type which include sub-G band, 2.4GHz band, and sub-G& 2.4GHz bands. The chips are classified with 2 temperature range as -40°-+85° and -40°-+125°. And there are many packages(QFN32, QFN40, QFN48, QFN68, and BGA125) to select.

There are also many SiP and PCB modules such as MGM12P, MGM13P/S, MGM210P/L for customer selection.
Applications:

Home and Building Automation, Beaconing, Lighting and Switching, Asset Tracking, Remote Control via Internet, etc.
