Product details
Overview
MCXW716AMFTAT from NXP Semiconductors is a low-power, highly secure multiprotocol wireless MCU integrating Bluetooth LE 5.3 and IEEE 802.15.4 (Thread/Matter/Zigbee) radios, an Arm Cortex-M33 application core running at up to 96 MHz, 1 MB flash, 128 KB SRAM, and EdgeLock™ Secure Enclave - deployed in smart home sensors, industrial gateways, and Matter-compliant edge devices.
For engineers reviewing the MCXW716AMFTAT datasheet, MCXW716AMFTAT pinout, MCXW716AMFTAT application, or MCXW716AMFTAT equivalent, key selection considerations include its dual-radio concurrency, CAN FD omission (vs. CMx variants), 48-pin HVQFN package with wettable flanks, ultra-low power-down modes (<3 µA RTC-active), and hardware-accelerated cryptography supporting AES-256, ECDSA, SHA2-512, and secure OTA updates.
Technical Context
The MCXW716AMFTAT implements a tri-core architecture: a 96 MHz Arm Cortex-M33 for application processing, a dedicated 64 MHz Cortex-M3 for the 802.15.4 radio stack, and an isolated EdgeLock Secure Enclave handling cryptographic operations, secure boot, and key lifecycle management. It supports full simultaneous dual-PAN operation for Thread and Zigbee without software arbitration.
Its RF subsystem includes integrated balun, single-ended 2.4 GHz port, –103 dBm 802.15.4 RX sensitivity at 250 kbps, and –106 dBm BLE Long Range RX sensitivity at 125 kbps. The FlexCAN peripheral is omitted per ordering table - distinguishing it from MCXW716CMFTAT - confirming this variant targets wireless-only industrial and smart home endpoints where CAN FD is not required.
Key Specifications

Pinout & Package
MCXW716AMFTAT is housed in a 48-pin HVQFN package (SOT619-17(D)) measuring 6 × 6 × 0.85 mm with 0.5 mm pitch and wettable flanks for solder joint inspection. Pin functions are validated per NXP's MCXW71RM Reference Manual and datasheet Section 5.1 (Pinout Table).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_IO_ABC | Digital I/O supply rail | 1.71–3.6 V input powering Ports A/B/C, Flash, and analog comparators - requires local decoupling for noise-sensitive radio operation. |
| VDD_CORE | Core logic supply | 1.0–1.21 V domain for Cortex-M33 and interconnect - supplied internally by Core_LDO or externally for precise voltage control. |
| RF_IN/OUT | 2.4 GHz transceiver port | Single-ended bidirectional RF interface with integrated balun - connects directly to matching network and antenna without external balun. |
| XTAL_RF | 32 MHz crystal oscillator input | Drives high-accuracy RF timing; requires 32 MHz ±10 ppm crystal with load capacitance matching datasheet spec (12 pF typical). |
| RTC_XTAL | 32.768 kHz crystal input | Enables precision real-time clock with <1 ppm drift over temperature - critical for scheduled Matter OTA updates and time-synchronized Thread networks. |
| SWD_DIO / SWD_CLK | ARM Serial Wire Debug interface | Two-pin debug port supporting secure programming and run-time debugging - accessible only in non-secure state unless authorized via TRDC. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCXW716CMFTAT | Includes FlexCAN supporting CAN FD (ISO 11898-1); identical radio, memory, and security specs. | Required for industrial fieldbus integration (e.g., PLC-to-Thread bridge); adds ~$0.45 BOM cost. | Select when CAN FD connectivity to legacy machinery or motor drives is mandatory. |
| EFR32MG24B310F1536IM48-B | Silicon Labs chip with same 802.15.4/Bluetooth LE 5.3 dual-radio, but no Matter stack pre-certification or EdgeLock-grade enclave. | Lacks PSA Level 3 certification and hardware PRINCE encryption; requires external secure element for Matter compliance. | Choose for cost-sensitive consumer devices where full PSA certification is not mandated. |
Compared with MCXW716CMFTAT, the MCXW716AMFTAT removes CAN FD to reduce die size and cost while retaining identical wireless performance and security - making it optimal for pure wireless edge nodes. Versus EFR32MG24, it delivers certified Matter readiness and stronger hardware root-of-trust out-of-box.

FAQ
Does MCXW716AMFTAT support CAN FD communication?
No, MCXW716AMFTAT does not support CAN FD. Per NXP's official Ordering Information table, the "A" prefix in the part number denotes absence of FlexCAN - unlike the "C"-prefix variants (e.g., MCXW716CMFTAT). This variant is optimized for wireless-only applications such as Matter end devices and Thread border routers where CAN FD is unnecessary.
What wireless protocols are supported natively by MCXW716AMFTAT?
MCXW716AMFTAT natively supports Bluetooth Low Energy 5.3 and IEEE 802.15.4, enabling certified implementations of Thread 1.3.1, Matter 1.3, and Zigbee 3.0. All protocol stacks - including Matter SDK, OpenThread, and ZBOSS - are pre-validated and hosted in on-chip memory, eliminating external host processor dependency for standalone operation.
Is MCXW716AMFTAT qualified for industrial temperature range?
Yes, MCXW716AMFTAT is fully qualified for –40 °C to +125 °C ambient operating temperature, meeting industrial-grade reliability requirements. Its thermal specifications, junction temperature limits, and DC/DC regulator performance are validated across this range per JEDEC JESD22-A103 and JESD22-A104 standards.
How does MCXW716AMFTAT achieve secure over-the-air (OTA) firmware updates?
MCXW716AMFTAT performs secure OTA updates using its EdgeLock Secure Enclave: firmware images are cryptographically signed (ECDSA-P521), verified before execution, and decrypted on-the-fly via PRINCE XEX mode. The update process enforces rollback protection, image authenticity, and confidentiality - all enforced in hardware without CPU intervention.
What is the maximum RF output power of MCXW716AMFTAT?
The MCXW716AMFTAT supports programmable transmit output power up to +10 dBm for both Bluetooth LE and IEEE 802.15.4 radios. At 0 dBm, typical TX current is 4.6 mA (DC-DC buck mode, 3.3 V); at +10 dBm, it rises to 18.7 mA - enabling flexible range/power trade-offs in battery-constrained deployments.
