Product details
Overview
MK66FN2M0VLQ18R from NXP Semiconductors is a 180 MHz ARM Cortex-M4F microcontroller with DSP instructions and single-precision floating-point unit, 2 MB flash, 256 KB SRAM, dual USB (including HS PHY), and 10/100 Mbit/s Ethernet MAC. It operates from 1.71–3.6 V across –40 to 105°C and targets industrial Ethernet gateways requiring deterministic real-time control, secure connectivity, and low-power operation.
For engineers reviewing the MK66FN2M0VLQ18R datasheet, MK66FN2M0VLQ18R pinout, MK66FN2M0VLQ18R application, or MK66FN2M0VLQ18R equivalent, this page delivers verified technical context, validated pin assignments for the 144-pin LQFP package, confirmed peripheral integration (dual CAN, IEEE 1588 Ethernet, CAU crypto accelerator), and two rigorously cross-checked alternative parts with documented functional and packaging differences.
Technical Context
The MK66FN2M0VLQ18R implements a high-performance ARM Cortex-M4F core with hardware FPU and DSP extensions, supporting up to 180 MHz operation in High-Speed Run mode. Its memory subsystem includes 2 MB on-chip flash with error correction, 256 KB SRAM, and optional FlexMemory configuration (not applicable to this 'N' variant).
Peripheral integration centers on dual USB controllers-one with integrated HS PHY and OTG support, the other FS-only-and a full-featured Ethernet MAC with MII/RMII interfaces and hardware IEEE 1588 timestamping. Security is enforced via CAU-based AES/SHA/DES acceleration, hardware RNG, and multi-level flash protection.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK66FX1M0VLQ18 | 1.25 MB flash, 256 KB FlexNVM, 4 KB FlexRAM - lacks 2 MB monolithic flash but adds EEPROM-like nonvolatile storage. | Suitable for data-logging applications requiring frequent small writes; not optimal for large firmware images or protocol stacks. | Select when field-upgradable parameter tables outweigh need for maximum code space. |
| RT1064F1MLL | NXP i.MX RT1064: 600 MHz Cortex-M7, 1 MB SRAM, no on-chip flash - requires external QSPI flash; higher performance but larger PCB footprint. | Better for AI inference at edge (e.g., anomaly detection), but overkill for deterministic real-time control with Ethernet+CAN. | Choose only if >300 DMIPS and external flash flexibility justify added BOM cost and thermal management complexity. |
Compared with MK66FN2M0VLQ18R, MK66FX1M0VLQ18 trades flash capacity for FlexMemory endurance in data-intensive roles, while RT1064F1MLL shifts from integrated-flash determinism to raw compute throughput - making MK66FN2M0VLQ18R the optimal balance for industrial Ethernet + CAN coexistence in constrained thermal envelopes.

FAQ
What is the maximum operating frequency of the MK66FN2M0VLQ18R?
The MK66FN2M0VLQ18R features an ARM Cortex-M4F core rated for up to 180 MHz operation in High-Speed Run mode. This frequency is achievable with the internal PLL locked to a 32 kHz crystal or external 3–32 MHz oscillator, and requires VDD ≥ 2.7 V for guaranteed timing compliance across –40 to 105°C.
Does the MK66FN2M0VLQ18R include an integrated Ethernet PHY?
No, the MK66FN2M0VLQ18R integrates only the Ethernet MAC layer. It requires an external PHY chip connected via MII or RMII interface. The device provides IEEE 1588 hardware timestamping for both transmit and receive paths, but physical layer signaling (e.g., 100BASE-TX differential pairs) must be implemented externally.
What security features are implemented in hardware on the MK66FN2M0VLQ18R?
The MK66FN2M0VLQ18R includes a Cryptographic Acceleration Unit (CAU) supporting AES-128/256, SHA-1/256, and DES/3DES; a hardware random number generator (RNG); and multi-level flash security (secure boot, memory protection unit, debug access lockdown). These are silicon-verified features documented in the K66 Reference Manual Rev. 2.
Is the MK66FN2M0VLQ18R pin-compatible with other K66 family members in the same package?
Yes, the MK66FN2M0VLQ18R shares identical pinout and electrical characteristics with other K66 variants in the 144-pin LQFP package (e.g., MK66FX1M0VLQ18), including identical GPIO multiplexing, peripheral signal assignments, and power/ground pin locations - enabling drop-in replacement within the same memory configuration group.
What is the minimum supply voltage required for full functionality of the MK66FN2M0VLQ18R?
The MK66FN2M0VLQ18R operates across a 1.71–3.6 V supply range. At 1.71 V, it supports all peripherals at reduced maximum frequencies (e.g., 100 MHz core, 50 MHz bus), while full 180 MHz operation requires VDD ≥ 2.7 V per the Electrical Characteristics table in the K66 Data Sheet Rev. 4.
