NXP Semiconductors has unveiled two new wireless microcontrollers (MCUs) expanding its portfolio of Matter solutions. The RW612 and the K32W148 wireless MCUs combine advanced edge processing capabilities and integrated security to streamline development, simplify IoT designs, and reduce costs for Matter-enabled smart home devices.
The Matter standard developed, within the Connectivity Standards Alliance by a consortium of industry leaders, including NXP, ease device interoperability and lower cost in smart home applications. The standard enables all devices – no matter the brand or ecosystem – to communicate seamlessly and securely. The new NXP devices make it easier for developers to address their specific needs and integrate Matter functionality into their smart home devices.
The RW612
The RW612 is the industry’s first secure tri-radio wireless MCU, according to NXP. The RW612 is integrated with an i.MX RT crossover MCU, which simplifies design by supporting the Matter standard. The wireless MCU features concurrent, multi-protocol support for Wi-Fi 6, Bluetooth Low Energy 5.3, and 802.15.4, and supports Thread or Zigbee. Smart-home applications include thermostats, garage door openers, door locks, IP cameras, robotic vacuums, and smart appliances.
Leveraging an integrated tri-radio and advanced edge processing capabilities from the EdgeVerse i.MX RT crossover MCU family, the RW612 features an Arm Cortex -M33 MCU subsystem with TrustZone-M. The wireless MCU also includes on-chip SRAM and high-performance configurable peripherals, including Ethernet, an LCD controller, and five FlexComm modules to support a variety of serial protocols. The RW612 is supported by the unified MCUXpresso development environment to reduce time to market.
The K32W148
The K32W148 multi-protocol wireless MCU, featuring a tri-core architecture, also features advanced processing capabilities with multi-protocol enablement across Thread, Bluetooth Low Energy 5.3, and Zigbee for devices such as smart plugs, smart lighting, and low-power smart devices and sensors. Multi-protocol enablement reduces costs and simplifies antenna design with a single antenna configuration, said NXP.
The K32W148 includes dual-PAN capability to simplify the co-existence of multiple IEEE 802.15.4 networks such as Thread and Zigbee. Architected with separated radio and security execution environments, the wireless MCU’s main Arm Cortex-M33 core and memory are available for the customer’s application. Like the RW612, it is also supported by the unified MCUXpresso development environment to reduce time to market.
Security
Both wireless MCUs are part of NXP’s EdgeLock Assurance program, a secure-by-design approach, which includes protection against remote and local software attacks. It supports secure boot, secure debug, and secure over-the-air firmware updates, with an immutable root-of-trust, hardware accelerated cryptography, and lifecycle management.
They also work with the EdgeLock SE05x secure element and EdgeLock A5000 secure authenticator. These discrete security components with optionally pre-injected keys and certificates provide a Common Criteria EAL6+ certified turnkey plug-in solution, which delivers additional tamper resistance and support for additional security use cases (such as device integrity protection or secure UWB ranging), said NXP. Both devices also support the NXP EdgeLock 2GO service for provisioning and management of device credentials from manufacturing and through the device lifecycle.
The RW612 and K32W148 are currently sampling.
