Product details
Overview
RW612CHN/A2IMP 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 RW612CHN/A2IMP datasheet, RW612CHN/A2IMP pinout, RW612CHN/A2IMP application, or RW612CHN/A2IMP equivalent, key selection considerations include its single 3.3 V supply operation, integrated EdgeLock security (PSA L3/SESIP L3 certified), dual-band Wi-Fi 6 throughput (MCS9), +21 dBm Wi-Fi Tx power, and 151-pin WLCSP package for space-constrained IoT edge nodes.
Technical Context
The RW612CHN/A2IMP implements a tightly coupled tri-radio architecture: Wi-Fi 6 MAC/baseband and RF (2.4/5 GHz, 1×1, 20 MHz channel) operate alongside independent Bluetooth 5.2 and 802.15.4 link-layer processors, all sharing a unified security root via EdgeLock hardware TEE and PUF-based key management.
Its MCU subsystem delivers deterministic real-time control with IEEE 1588-capable RMII Ethernet, five FlexComm peripherals (SPI/I²C/I²S/UART configurable), LCD interface, and PowerQuad co-processor for cryptographic acceleration - all powered from one 3.3 V rail with per-subsystem power gating and fast wake-up from low-leakage always-on domain.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESP32-H2 (Espressif) | Single 2.4 GHz 802.15.4 + BLE 5.0; no Wi-Fi; 160 MHz RISC-V core; 384 KB SRAM; no PSA L3 certification | Limited to Thread/Zigbee-only edge nodes; cannot serve as Matter Controller or Wi-Fi backhaul | Select when cost-sensitive, Wi-Fi-free Thread end-devices are sufficient and security requirements are below PSA L3 |
| CC3350 (Texas Instruments) | Dual-band Wi-Fi 6 + BLE 5.3; no 802.15.4; 200 MHz Arm Cortex-M4F; 1 MB SRAM; supports Matter over Wi-Fi only | Suitable for Wi-Fi-first hubs but lacks native Thread Border Router capability and requires external MCU for full Matter bridging | Choose when Wi-Fi throughput priority exceeds mesh networking needs and external PSRAM expansion is acceptable |
Compared with ESP32-H2 and CC3350, RW612CHN/A2IMP uniquely integrates all three radios with PSA L3-certified EdgeLock security and on-die RF front-ends - enabling single-chip Matter Controller, Thread Border Router, and Wi-Fi 6 gateway functionality without external security or RF components.

FAQ
What radio protocols does the RW612CHN/A2IMP natively support?
The RW612CHN/A2IMP natively supports IEEE 802.11ax (Wi-Fi 6) on 2.4 GHz and 5 GHz bands, Bluetooth 5.2 with 2 Mbps mode and long-range extensions, and IEEE 802.15.4 for Thread 1.3.0 and Zigbee 3.0. All three radios operate concurrently and are fully integrated into the RW612CHN/A2IMP silicon - no external transceivers or protocol stacks are required for Matter-over-Wi-Fi or Matter-over-Thread implementations.
Does the RW612CHN/A2IMP require external flash memory to run Matter firmware?
No, the RW612CHN/A2IMP includes 1.2 MB of on-chip SRAM and supports encrypted execute-in-place (XIP) from external flash via its Quad FlexSPI interface with on-the-fly AES-128 decryption. While external flash is typically used for firmware storage, the RW612CHN/A2IMP can boot and execute Matter stack directly from secure XIP memory - eliminating software decryption latency and protecting code confidentiality throughout the execution path.
Is the RW612CHN/A2IMP pin-compatible with other RW61x variants like RW610?
No, the RW612CHN/A2IMP is not pin-compatible with RW610 or other RW61x variants. The RW612CHN/A2IMP uses a 151-pin WLCSP package optimized for tri-radio integration and high-density routing, whereas RW610 uses an 116-pin HVQFN package with different pin assignments, power sequencing, and RF interface layout. Board-level redesign is required when migrating between these variants.
What security certifications apply to the RW612CHN/A2IMP?
The RW612CHN/A2IMP is certified under PSA Certified Level 3 and SESIP Level 3, with hardware root of trust validated by NXP's EdgeLock Assurance program. It includes tamper-resistant secure boot, hardware-accelerated cryptography (AES/SHA/ECC/RSA), and PUF-based key generation - meeting IEC 62443-3-3 and NIST SP 800-193 requirements for secure firmware updates and lifecycle management in the RW612CHN/A2IMP.
Can the RW612CHN/A2IMP operate as both a Matter Controller and a Thread Border Router simultaneously?
Yes, the RW612CHN/A2IMP is architected to run Matter Controller, Thread Border Router, and Matter Bridge functions concurrently within its single-chip architecture. Its tri-radio subsystems, deterministic Cortex-M33 real-time scheduling, and EdgeLock-secured TEE enable simultaneous local device commissioning (Controller), IPv6 routing between Thread and Wi-Fi networks (Border Router), and protocol translation for cloud-bound traffic (Bridge) - all without external co-processors or security elements in the RW612CHN/A2IMP.
