The K32W148 is highly integrated multiprotocol wireless IoT device with
support for IEEE 802.15.4 mesh network protocols, Matter over Thread, Zigbee,
and Bluetooth Low Energy 5.3.
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. These devices also include a rich set of MCU digital and analog
peripherals and multiple serial communication interfaces for embedded
Supporting the application core are a dedicated radio core and an isolated
EdgeLock secure enclave. The radio core, with its 256 kB Flash and 88 kB SRAM,
offloads low-level radio operations from the application core, freeing
resources and optimizing system level current draw. The EdgeLock secure
enclave enables advanced security features such as key creation and storage,
secure lifecycle management, secure boot and cryptographic acceleration in a
protected execution environment.
