SiMG301 - Series 3 Low Power Multiprotocol Wireless SoC
SiMG301
Purpose-built for line-powered smart devices, with multiprotocol support

Product Description
The SiMG301 SoC family belongs to our next generation Series 3 platform that further extends our leadership in ultra-low power IoT SoCs and modules. Series 3 brings new levels of compute, security, RF performance, and power efficiency that are necessary to address emerging IoT markets. The SiMG301 is purpose built for line powered smart devices including LED lighting, plugs and switches.The multi-core device has an ARM® Cortex®-M33 running up to 150 MHz for application development and dedicated cores for the radio and security engine. Our Secure Vault™ High, designed for PSA level 3 certification, helps to protect both the data and the device. Memory options of up to 4 MB Flash and 512 kB RAM allow for more demanding applications including support for our concurrent multiprotocol (CMP) that can run both Zigbee and Matter over Thread at the same time on a single device, simplifying SKU management for the product manufacturer and ease of use for the end user.
Optimized for LED lighting applications, select SiMG301 devices integrate key features including a PIXELRZ single wire communication interface for LED controller ICs as well as a LED pre-driver that enables low level and consistent dimming, resulting in a simplified design, reduced BOM, and lower product cost.
