Constructed on a 22-nm course of, Silicon Labs’ SiXG301 and SiXG302 wi-fi SoCs ship improved compute efficiency and power effectivity. As the primary members of the Sequence 3 portfolio, they aim each line- and battery-powered IoT gadgets.
Designed for line-powered purposes reminiscent of LED good lighting, the SiXG301 integrates an LED pre-driver and a 32-bit Arm Cortex-M33 processor working at as much as 150 MHz. It helps concurrent multiprotocol operation with Bluetooth, Zigbee, and Matter over Thread, and contains 4 MB of flash and 512 kB of RAM. At present in manufacturing with choose prospects, the SiXG301 is anticipated to be typically out there in Q3 2025.
Extending the Sequence 3 platform to battery-powered purposes, the SiXG302 encompasses a power-efficient structure that consumes simply 15 µA/MHz when energetic—as much as 30% decrease than comparable gadgets. It’s well-suited for battery-powered wi-fi sensors and actuators utilizing Matter or Bluetooth. Sampling is anticipated to start in 2026.
The SiXG301 and SiXG302 households will initially embody two forms of gadgets: ‘M’ variants (SiMG301 and SiMG302) for multiprotocol help, and ‘B’ variants (SiBG301 and SiBG302) optimized for Bluetooth LE.
