KW45: 32-Bit Bluetooth^® 5.3 Long-Range MCUs with CAN FD and LIN Bus Options, Arm^® Cortex

KW45’s three-core architecture integrates a 96 MHz CM33 application core,

dedicated CM3 radio core and an isolated EdgeLock Secure Enclave. The

Flash-based radio core with dedicated SRAM delivers a highly configurable and

upgradeable software-implemented radio, freeing resources on the main core for

customer application space.

The Bluetooth Low Energy 5.3-compliant radio

supports up to 24 simultaneous secure connections. The EdgeLock Secure

Enclave’s isolated execution environment provides a set of cryptographic

accelerators, key store operations and secure lifecycle management that

minimizes main core security responsibilities.

The KW45 MCU additionally

integrates FlexCAN, helping enable seamless integration into an automobile’s

in-vehicle or industrial CAN communication network. The FlexCAN module can

support CAN’s flexible data rate (CAN FD) for increased bandwidth and lower

latency.
