NXP Semiconductors MCXW716CMFTAR

Overview

MCXW716CMFTAR from NXP Semiconductors is a low-power, highly secure, single-chip multiprotocol wireless MCU integrating Bluetooth LE 5.3, IEEE 802.15.4 (Thread/Matter/Zigbee), and FlexCAN supporting CAN FD per ISO 11898-1. It features a tri-core architecture (Cortex-M33 application core + dedicated CM3 radio core + EdgeLock Secure Enclave), 1 MB flash, 128 KB SRAM, and operates across –40 °C to 125 °C for industrial IoT edge nodes.

For engineers reviewing the MCXW716CMFTAR datasheet, MCXW716CMFTAR pinout, MCXW716CMFTAR application, or MCXW716CMFTAR equivalent, this page delivers verified specifications, package mapping to 48-pin HVQFN (7 × 7 × 0.85 mm, 0.5 mm pitch, wettable flanks), real-world power consumption data (<5.3 mA active @96 MHz, <3 μA power-down with RTC), and validated alternative options for Matter/Thread gateway and industrial CAN FD sensor node designs.

Technical Context

The MCXW716CMFTAR implements a hardware-isolated tri-core architecture: a 96 MHz Arm Cortex-M33 application core with TrustZone-M and FPU handles host stacks and user applications; a dedicated 64 MHz CM3 narrow-band radio core manages IEEE 802.15.4 and BLE link layers independently; and the EdgeLock Secure Enclave provides hardware-accelerated crypto (AES-128/192/256, ECC, SHA2, ChaCha20), secure key storage, and tamper detection. All three domains are enforced by the Trusted Resource Domain Controller (TRDC).

Its dual-PAN 2.4 GHz radio supports simultaneous Thread and Zigbee operation with –103 dBm RX sensitivity at 250 kbps (802.15.4) and –106 dBm at 125 kbps (BLE Long Range), while the integrated FlexCAN module complies fully with CAN FD ISO 11898-1, enabling deterministic industrial control messaging up to 5 Mbps. Power management includes ultra-low-leakage Smart Power Switch (<100 nA sleep current) and multiple retention modes.

Key Specifications

Pinout & Package

FAQ

What wireless protocols does the MCXW716CMFTAR support natively?

The MCXW716CMFTAR natively supports Bluetooth Low Energy 5.3, IEEE 802.15.4 (for Thread 1.3, Matter 1.0, and Zigbee 3.0), and FlexCAN compliant with CAN FD per ISO 11898-1. All protocol stacks-including Matter and Thread certified software-are pre-integrated and tested on-chip. The MCXW716CMFTAR does not require external radio ICs or protocol co-processors to implement any of these standards.

Does the MCXW716CMFTAR include hardware security features beyond standard TrustZone-M?

Yes. In addition to Arm TrustZone-M, the MCXW716CMFTAR integrates the EdgeLock Secure Enclave-a physically isolated security subsystem featuring hardware cryptographic accelerators (AES-128/192/256, ECC, SHA2, ChaCha20), true random number generation (NIST SP 800-90A/B compliant), secure key storage, tamper detection with timestamping, and secure debug disable. The MCXW716CMFTAR also supports PRINCE on-the-fly flash encryption and immutable secure boot from ROM.

What is the operating temperature range and qualification level of the MCXW716CMFTAR?

The MCXW716CMFTAR is qualified for industrial applications with an ambient operating temperature range of –40 °C to 125 °C and a junction temperature range of –40 °C to 125 °C. It meets JEDEC JESD22-A103 storage life requirements and IPC/JEDEC J-STD-020 moisture sensitivity level 3. The MCXW716CMFTAR is not automotive-qualified (AEC-Q100), but its industrial qualification ensures reliability in harsh factory and building environments.

How many GPIOs does the MCXW716CMFTAR provide, and what package does it use?

The MCXW716CMFTAR provides 29 general-purpose I/O pins and is packaged in a 48-pin HVQFN (SOT619-17(D)) measuring 7 mm × 7 mm × 0.85 mm with 0.5 mm pitch and wettable flanks. This package supports full CAN FD differential signaling, dual crystal interfaces (32 MHz RF and 32.768 kHz RTC), and RF matching without external balun-reducing layout complexity and bill-of-materials cost.

What power consumption figures are guaranteed for the MCXW716CMFTAR in low-power modes?

The MCXW716CMFTAR guarantees less than 3 μA in Power-down mode with RTC active and 32 KB SRAM retention, and less than 1.5 μA in Deep Power-down mode with RTC active. Its Smart Power Switch achieves sub-100 nA sleep current with wake-up capability via internal timer or GPIO. These values are measured at 25 °C with DC-DC regulator enabled and are specified in the official NXP MCX W71 datasheet Rev. 2 (09/2024). The MCXW716CMFTAR delivers these figures without external PMIC assistance.
