Product details
Overview
RW612ET/A2IK from NXP Semiconductors is a secure tri-radio wireless MCU integrating a 260 MHz Arm Cortex-M33 with TrustZone-M, 1.2 MB on-chip SRAM, and concurrent Wi-Fi 6 (2.4/5 GHz), Bluetooth 5.2, and 802.15.4 radios - enabling Matter-over-Wi-Fi/Thread operation in smart home hubs and industrial gateways.
For engineers reviewing the RW612ET/A2IK datasheet, RW612ET/A2IK pinout, RW612ET/A2IK application, or RW612ET/A2IK equivalent, key selection criteria include dual-band Wi-Fi 6 throughput (MCS9), +21 dBm integrated PA output, EdgeLock security certification (PSA L3/SESIP L3), and support for Matter Controller/Border Router roles without external co-processors.
Technical Context
The RW612ET/A2IK implements a tightly coupled tri-radio architecture: Wi-Fi 6 MAC/baseband and RF (1×1, 20 MHz, 2.4/5 GHz) operate independently from a dedicated Bluetooth LE/802.15.4 CPU and RF subsystem supporting Thread 1.3.2 and Zigbee 3.0 stacks.
Its MCU subsystem features TrustZone-M isolation, hardware-accelerated cryptography (AES/SHA/ECC/RSA), PUF-based key generation, and Quad FlexSPI with on-the-fly decryption for secure XIP from external flash - all powered from a single 3.3 V supply with integrated buck/LDO regulators.
