Product details
Overview
RW612ET/A2IY 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 RW612ET/A2IY datasheet, RW612ET/A2IY pinout, RW612ET/A2IY application, or RW612ET/A2IY equivalent, key selection criteria 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 support for Matter Controller/Border Router/Bridge roles.
Technical Context
The RW612ET/A2IY implements three independent radio subsystems sharing a unified security root: Wi-Fi 6 MAC/baseband with TWT and dual-carrier modulation; Bluetooth 5.2 Link Layer with 2 Mbps PHY and advertising extensions; and IEEE 802.15.4 MAC supporting Thread 1.3.2 and Zigbee 3.0 stacks. All radios interface via dedicated CPUs and share secure memory-mapped peripherals.
Its MCU subsystem features hardware-accelerated cryptography (AES-128/256, SHA-256, ECC P-256, RSA-2048), TRNG, PUF-based key derivation, and secure boot enforced by immutable ROM code. Power management includes independent subsystem wake-up via GPIO/IRQ/RTC and low-leakage always-on domain for sub-100 µs wake latency.
