TI introduces Matter-enabled wireless MCU software

Semiconductor company Texas Instruments has introduced new Matter-enabled software development kits for its Wi-Fi and Thread SimpleLink wireless microcontrollers (MCUs) that are designed to streamline adoption of the Matter protocol in Internet of Things (IoT) applications. Engineers can use the new software and wireless MCUs such as the CC3235SF and CC2652R7 to create ultra-low-power and secure, battery-powered smart home and industrial automation IoT applications that seamlessly connect with devices across proprietary ecosystems.

The software, says the company, builds on TI’s close involvement with the Connectivity Standards Alliance and innovation in the 2.4-GHz connectivity space.

“In a matter of weeks, we’re quickly seeing alliance members building on the new capabilities of Matter and bringing innovation to the ecosystem, in this case a streamlined approach for MCUs and IoT applications over Wi-Fi and Thread,” says Chris LaPre, Head of Technology at the Connectivity Standards Alliance. “TI’s new wireless MCUs for IoT applications will help designers seamlessly and securely connect with interoperable Matter devices.”

Matter is a royalty-free connectivity protocol developed by the alliance, formerly the Zigbee Alliance. Matter runs on Thread and Wi-Fi network layers and uses Bluetooth Low Energy for commissioning, allowing devices from different ecosystems to communicate, even if they are manufactured by different brands. By providing a unified application layer based on proven technologies, manufacturers can leverage this open-source protocol to accelerate IoT development.

As a board member of the alliance and one of the participants in the development of Matter, says the company, it can help engineers build wider and more interconnected IoT ecosystems – overcoming current compatibility challenges caused by otherwise fragmented ecosystems. In addition to working alongside the alliance, the company is also a contributor within the Thread Group and a member of the Wi-Fi Alliance.

New TI SimpleLink wireless MCUs can help designers reduce standby power consumption up to 70% in Thread applications compared to competing devices, extending battery life up to four years while using five-second polling. For long-range connectivity applications, the highly efficient integrated power amplifier in these wireless MCUs enables reliable connectivity by consuming 101 mA at +20 dBm – claimed as the industry’s lowest power consumption – further reducing battery power consumption at higher output power.

Designers of Matter-enabled Wi-Fi applications, says the company, can leverage TI’s dual-band, multilayer security approach to protect device data and secure against cyberthreats without the need for additional external components. Engineers can start prototyping today by requesting LaunchPad development kits for Thread LP-CC2652R7 ($39.99) and Wi-Fi LP-CC3235SF ($54.99).

The CC2652R7 and the CC3235SF are available now, with pricing in 1,000-unit quantities starting at $3.01 for the CC2652R7 and $4.53 for the CC3235SF.
