NXP Semiconductors MCXW716AMFPAR

Overview

MCXW716AMFPAR from NXP Semiconductors is a low-power, highly secure multiprotocol wireless MCU integrating Bluetooth Low Energy 5.3, IEEE 802.15.4 (Thread/Matter/Zigbee), and no CAN FD interface. It features a tri-core architecture (Arm Cortex-M33 @ 96 MHz + dedicated radio CM3 core), 1 MB flash, 128 KB SRAM, and EdgeLock™ Secure Enclave for hardware cryptographic acceleration. It targets battery-powered smart home sensors and industrial edge nodes requiring Matter-over-Thread or BLE mesh connectivity.

For engineers reviewing the MCXW716AMFPAR datasheet, MCXW716AMFPAR pinout, MCXW716AMFPAR application, or MCXW716AMFPAR equivalent, key selection considerations include its 40-pin HVQFN package, absence of FlexCAN, dual-radio simultaneous PAN support, ultra-low power-down current (<3 μA with RTC active), and certified Matter 1.3 stack readiness - all critical for constrained IoT endpoint design.

Technical Context

The MCXW716AMFPAR implements a hardware-isolated tri-core architecture: an Arm Cortex-M33 application core (96 MHz, TrustZone-M, FPU, 8 KB code cache), a dedicated narrowband radio CM3 core (64 MHz) for IEEE 802.15.4/Bluetooth LE link-layer processing, and an EdgeLock Secure Enclave managing cryptographic operations, secure boot, and tamper detection. This separation ensures deterministic real-time radio performance while maintaining application flexibility and security boundary integrity.

Its RF subsystem integrates two independent radios sharing a single-ended 2.4 GHz RF port: the IEEE 802.15.4 radio achieves –103 dBm sensitivity at 250 kbps and supports synchronized broadcast to sleepy devices; the Bluetooth LE 5.3 radio delivers –106 dBm long-range sensitivity and up to 24 simultaneous connections. Both radios operate with tested, production-ready Matter, Thread, Zigbee, and BLE software stacks.

Key Specifications

Pinout & Package

MCXW716AMFPAR is housed in a 40-pin HVQFN package (SOT618-13(DD)), measuring 6 × 6 × 0.85 mm with 0.5 mm pitch and wettable flanks for enhanced solder joint inspection. Pin functions are defined per the official NXP MCXW71RM Reference Manual and validated against the MCXW716AMFPAR-specific pinout table in the datasheet.

FAQ

Does MCXW716AMFPAR support CAN FD?

No, MCXW716AMFPAR does not include FlexCAN hardware. It belongs to the "AM" variant subfamily explicitly omitting CAN FD support, unlike the "CM" variants (e.g., MCXW716CMFPA R). This omission reduces silicon area and cost while preserving full Bluetooth LE 5.3 and IEEE 802.15.4 (Thread/Matter/Zigbee) functionality. Engineers requiring CAN FD must select a "CM"-suffixed part number.

What is the maximum transmit power supported by MCXW716AMFPAR?

The MCXW716AMFPAR supports programmable transmit output power up to +10 dBm for both its IEEE 802.15.4 and Bluetooth LE 5.3 radios. At +10 dBm, the typical TX current is 18.7 mA (DC-DC buck mode, 3.3 V supply). This enables reliable 2.4 GHz link budgets exceeding 110 dB in indoor smart home environments without external PA stages.

Is MCXW716AMFPAR qualified for industrial temperature range?

Yes, MCXW716AMFPAR is qualified for industrial temperature operation from –40 °C to +125 °C (ambient), with corresponding junction temperature limits. Its thermal handling ratings include solder reflow up to 260 °C (lead-free) and storage temperature from –55 °C to +150 °C, meeting JEDEC JESD22-A103 and IPC/JEDEC J-STD-020 standards for ruggedized deployment.

How many GPIOs are available on MCXW716AMFPAR?

MCXW716AMFPAR provides up to 22 GPIOs in its 40-pin HVQFN package. These are distributed across Ports A, B, C, and D, with specific pins multiplexed for LPUART, LPI2C, LPSPI, FlexIO, ADC, and comparator functions. All GPIOs support interrupt generation and can be configured for wake-up from deep power-down modes.

Does MCXW716AMFPAR include hardware cryptographic acceleration?

Yes, MCXW716AMFPAR integrates a comprehensive hardware cryptography suite within its EdgeLock Secure Enclave, including AES-128/192/256 (GCM, CCM, CBC), ECC NIST P-256/384, SHA2-256/384, ECDSA, Ed25519, and ChaCha20. These accelerators operate independently of the application core, enabling secure OTA updates and Matter-compliant key exchange without compromising real-time sensor processing performance.
