Product details
Overview
RW612CET/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 2.4/5 GHz Wi-Fi 6 (802.11ax), 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 RW612CET/A2IK datasheet, RW612CET/A2IK pinout, RW612CET/A2IK application, or RW612CET/A2IK equivalent, key selection considerations include its single 3.3 V supply operation, EdgeLock® security certification (PSA L3, SESIP L3), integrated PA/LNA (+21 dBm Wi-Fi Tx, +15 dBm BLE/802.15.4 Tx), Quad FlexSPI with on-the-fly decryption, and 145-pin TFBGA package.
Technical Context
The RW612CET/A2IK implements a dual-band (2.4/5 GHz) 1×1 Wi-Fi 6 MAC/baseband with TWT support, MCS9 modulation, and integrated RF front-end (PA, LNA, T/R switch); its Bluetooth 5.2/802.15.4 subsystem supports concurrent LE 2 Mbps mode, long-range PHY, and Thread 1.3.0/Zigbee 3.0 protocol stacks.
Security is enforced via hardware root of trust: EdgeLock® Assurance-certified secure boot, PUF-based key generation, AES/SHA/ECC/RSA accelerators, and TrustZone-M-isolated execution environment - all validated to PSA Level 3 and SESIP Level 3 standards.

The RW612CET/A2IK serves as a unified Matter platform - operating simultaneously as a Matter Controller, Thread Border Router, and Matter Bridge. It enables local and cloud-based control across ecosystems by natively supporting Matter over Wi-Fi, Matter over Thread, and protocol translation between them. Its integrated tri-radio architecture and EdgeLock® security make RW612CET/A2IK the foundation for production-grade Matter-certified hubs and gateways.
Does the RW612CET/A2IK support secure over-the-air firmware updates?
Yes, the RW612CET/A2IK supports end-to-end secure OTA updates using EdgeLock 2GO provisioning and hardware-accelerated cryptographic signing. Updates are verified via immutable secure boot chain, with PUF-derived keys protecting firmware integrity. This implementation complies with PSA Certified Level 3 and IEC 62443-4-2 requirements - ensuring RW612CET/A2IK maintains trusted operation throughout its deployed lifecycle.
What package type and pin count does the RW612CET/A2IK use?
The RW612CET/A2IK uses an 8 mm × 8 mm, 0.5 mm pitch, 145-ball Thin Fine-Pitch Ball Grid Array (TFBGA) package with exposed thermal pad. This package supports industrial temperature range (–40°C to +85°C), standard reflow profiles, and high-density PCB layouts - confirmed in NXP document RW61XFS REV 0 and official RW612 product brief.
Can the RW612CET/A2IK operate from a single power supply?
Yes, the RW612CET/A2IK is designed to operate from a single 3.3 V external supply. Its integrated buck regulators and LDOs generate all required internal voltage domains, eliminating the need for multi-rail power management ICs. This simplifies power design and reduces system BOM cost - a confirmed feature in the RW612 datasheet and fact sheet.
Which wireless protocols does the RW612CET/A2IK support concurrently?
The RW612CET/A2IK supports concurrent IEEE 802.11ax (Wi-Fi 6) on 2.4 GHz and 5 GHz bands, Bluetooth 5.2 (including 2 Mbps mode and long-range PHY), and IEEE 802.15.4 (for Thread 1.3.0 and Zigbee 3.0).
