Product details
Overview
MCXW716AMFTAR from NXP Semiconductors is a low-power, highly secure multiprotocol wireless MCU integrating Bluetooth Low Energy 5.3 and IEEE 802.15.4 (Thread/Zigbee) radios, with no CAN FD interface, 96 MHz Arm Cortex-M33 application core, 1 MB flash, 128 KB SRAM, and EdgeLock™ Secure Enclave - deployed in smart home sensors, Matter-compliant bridges, and battery-powered industrial edge nodes.
For engineers reviewing the MCXW716AMFTAR datasheet, MCXW716AMFTAR pinout, MCXW716AMFTAR application, or MCXW716AMFTAR equivalent, this page delivers verified specifications, package mapping, security architecture details, power-mode current values, and validated alternative parts for IoT connectivity design and firmware stack selection.
Technical Context
The MCXW716AMFTAR implements a tri-core architecture: a 96 MHz Arm Cortex-M33 for application processing, a dedicated 64 MHz CM3 core for 802.15.4 link-layer execution, and an isolated EdgeLock Secure Enclave handling cryptographic acceleration, key management, and secure boot. It supports full simultaneous dual-PAN operation for concurrent Thread and Zigbee networks.
Its radio subsystem delivers –103 dBm RX sensitivity at 250 kbps (802.15.4), –106 dBm at 125 kbps (BLE Long Range), and +10 dBm programmable TX output; power management includes ultra-low leakage Smart Power Switch (<100 nA sleep current) and multiple power-down modes down to 300 nA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCXW716CMFTAR | Includes FlexCAN supporting CAN 2.0B and CAN FD (ISO 11898-1); identical radio, memory, and security specs | Required for industrial gateways interfacing with CAN-based PLCs or motor drives | Select MCXW716CMFTAR only if CAN FD bus integration is mandatory; otherwise MCXW716AMFTAR reduces BOM cost and layout complexity |
| EFR32MG24B310F1536IM48-B | Silicon Labs chip with same BLE 5.3 + Thread 1.3.0 support; lacks Arm TrustZone-M, PRINCE encryption, and EdgeLock enclave | Suitable for cost-sensitive consumer devices where NIST SP 800-193 compliance is not required | Choose EFR32MG24B310F1536IM48-B for simpler security needs and lower unit cost; MCXW716AMFTAR preferred for industrial-grade root-of-trust and secure debug lockdown |
Compared with MCXW716CMFTAR, MCXW716AMFTAR removes CAN FD hardware to reduce die size and power - ideal for pure wireless edge nodes.

FAQ
Does MCXW716AMFTAR support CAN FD communication?
No, MCXW716AMFTAR does not include FlexCAN hardware. It is the CAN-disabled variant within the MCX W71 family. The 'A' in the part number explicitly denotes absence of CAN FD capability, unlike 'C' variants such as MCXW716CMFTAR. All other wireless, security, and processing features remain identical.
What is the maximum transmit power supported by MCXW716AMFTAR's 2.4 GHz radio?
The MCXW716AMFTAR supports programmable transmit output power up to +10 dBm for both Bluetooth LE and IEEE 802.15.4 protocols. This value is measured at the RF_IN/OUT pin with integrated balun enabled and DCDC regulator in buck mode at 3.3 V supply.
How does MCXW716AMFTAR achieve secure over-the-air (OTA) updates?
MCXW716AMFTAR uses its EdgeLock Secure Enclave to validate signed firmware images via ECDSA-P256, decrypt payloads using AES-128-GCM, and perform atomic flash swaps with rollback protection. The PRINCE module enables on-the-fly decryption of encrypted firmware sections during execution.
Is MCXW716AMFTAR qualified for industrial temperature range?
Yes, MCXW716AMFTAR is fully qualified for industrial operation from –40 °C to +125 °C junction temperature. Its thermal specifications, voltage monitoring circuits (HVD/LVD), and packaging (HVQFN with wettable flanks) comply with industrial reliability standards including JEDEC JESD22-A103 and IPC/JEDEC J-STD-020.
What debug interfaces are available on MCXW716AMFTAR?
MCXW716AMFTAR provides ARM Serial Wire Debug (SWD) via dedicated SWD_DIO and SWD_CLK pins. Debug access is governed by EdgeLock Secure Enclave policies - enabling secure debug authentication, trace filtering, and privilege-level enforcement per TrustZone-M configuration.
