The KW45 product family is a low-power, highly secure, single-chip wireless MCU that integrates a high performance Bluetooth Low Energy version 5.3 radio and CAN FD for Automotive and Industrial applications.

The family 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 and 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.

For automotive applications, an integrated FlexCAN supporting CAN and CAN FD compliant with the ISO 11898-1 standard. The on-chip, low-power UARTs have LIN capabilities. The family is AEC-Q100 Grade 2 automotive certified, with an extended ambient operating temperature range up to +105 °C, MISRA C:2012, and Automotive SPICE (ASPICE) process compliant.
