The K32W14x product family is a low-power, highly secure, single chip multiprotocol wireless MCU that integrates a high performance Bluetooth Low Energy version 5.3 radio and an IEEE 802.15.4 radio supporting Thread, Matter and Zigbee. The K32W14x implements a tri-core architecture to isolate the connectivity, computing and security capabilities.

The multiprotocol radio is energy efficient, supports full simultaneous dual-PAN to enable Thread and Zigbee, and designed for Wi-Fi coexistence. The radio is supported with tested software stacks for Matter, Thread, Zigbee and Bluetooth Low Energy for standalone and hosted applications to enable a range of IoT and industrial applications.

The K32W14x integrates a state-of-the-art, scalable security architecture including Arm? TrustZone?-M, a resource domain controller and an isolated EdgeLock? Secure Enclave supporting hardware cryptographic accelerators, random number generators, key generation, storage and management, and secure debug. Flash memory contents can optionally be stored as encrypted data and then decrypted on-the-fly enabling protection of sensitive data and algorithms.
