The K32W148 wireless MCU simplifies development of IoT devices with modular
security and connectivity subsystems, allowing developers to focus on their
innovation. With its integrated RF subsystem and a total memory footprint between the application core and the networking subsystem of 1.25 MB Flash and 216 KB RAM, the K32W148 enables seamless integration of
Matter, Thread, Zigbee and Bluetooth Low Energy.
The K32W148 Arm® Cortex®-M33 main core, with 1 MB on-board flash and 128 KB
SRAM, has enough room and flexibility for complex applications and
over-the-air (OTA) upgrade capability without external memory. It also
includes a rich set of MCU digital and analog peripherals and multiple serial
communication interfaces for embedded connected applications.
Supporting the application core are a dedicated radio subsystem and an
isolated EdgeLock® secure enclave. The radio subsystem, with its 256 kB Flash
and 88 kB SRAM, offloads low-level radio operations from the application core,
freeing resources for the main application, providing robust wireless
performance and optimizing system level current draw. It also supports
hardware accelerated Dual-PAN which enables bridging use cases for Thread and
Zigbee with faster and more reliable time-slicing.
The EdgeLock secure enclave enables advanced security features such as key
generation and storage, secure lifecycle management, secure boot and
cryptographic acceleration in a protected execution environment. The K32W148
is also supported by NXP’s EdgeLock® 2GO service which can install keys and
certificates securely into the end devices and maintain the credentials
throughout their life cycle. This service is authorized by the
Connectivity Standards Alliance to serve as a Product Attestation Authority
for Matter device attestation certificates streamlining the process for device
manufacturers to develop and deploy a full Matter device.
