KW43 Knowledge Hub

[#1]

The KW43 product family is a low-power, secure, single-chip wireless MCU that integrates a high performance, Bluetooth Low Energy, Bluetooth Channel Sounding, EdgeLock Secure Accelerators, and various MCU peripherals targeted for Automotive applications.

The KW43 family utilizes an Arm® Cortex®-M33 core (Armv8-M architecture) running up to 96 MHz for customer applications. The family includes memory configurations of up to 1.5MB flash and 256 KB SRAM across all listed part numbers. All devices in the family integrate a state-of-the-art, scalable security architecture including Arm’s TrustZone®-M, a resource domain controller and an isolated EdgeLock Secure Accelerators supporting hardware cryptographic accelerators, random number generators and key generation, storage, and management along with secure debug. All members of the KW43 family are designed to be compliant to a SESIP Level 3 certification following the Arm PSA Level 3 profile.

KW43 uses dual Arm Core Cortex-M33 (‘CM33’) and supports multiple interfaces and security features. One is for application and system use and other is for radio link layer and both cores share a common flash of 1.5 MB.

The devices include a full certified Bluetooth LE 6.x controller stack with support for up to 10 simultaneous connections in any controller/peripheral combination. The multiprotocol radio subsystem integrated in the KW43 Family is energy efficient and is designed for Wi-Fi coexistence. The radio is supported with tested software stacks for Bluetooth Low Energy for standalone and hosted applications to enable a range of Automotive, IoT and industrial applications. There is also software and hardware support for 2.4 GHz proprietary protocols. To address ranging requirements, the Localization Engine (LCE) is integrated into the system for enhanced localization performance.

The KW43 series is supported by the MCUXpresso Developer Experience to optimize, ease and help accelerate embedded system development.
