NXP Semiconductors MK64FX512VDC12

Overview

MK64FX512VDC12 from NXP Semiconductors is a 120 MHz ARM® Cortex®-M4 microcontroller with FPU, 512 KB flash, 256 KB SRAM, and 83 GPIOs in a 144-pin LQFP package. It integrates USB OTG 2.0 (crystal-less), 10/100 Mbit/s Ethernet MAC (MII/RMII), dual 16-bit ADCs, two 12-bit DACs, CAN, six UARTs, and hardware AES/SHA-256 encryption - deployed in industrial gateways requiring real-time connectivity and secure edge processing.

For engineers reviewing the MK64FX512VDC12 datasheet, MK64FX512VDC12 pinout, MK64FX512VDC12 application, or MK64FX512VDC12 equivalent, key selection criteria include its 144 LQFP mechanical compatibility, Ethernet+USB coexistence capability, low-power stop mode current (≤5.8 µA with full state retention), and FlexMemory support for data logging in resource-constrained embedded systems.

Technical Context

The MK64FX512VDC12 implements a multi-layer bus architecture with AHB crossbar, supporting concurrent access to flash, SRAM, and peripherals. Its clock system includes PLL, FLL, 48 MHz IRC48M, and configurable 3–32 MHz crystal oscillator - enabling precise timing control for IEEE 1588 Ethernet synchronization and deterministic motor control via FlexTimer modules.

Security is enforced through dedicated hardware blocks: CRC engine for memory integrity, TRNG for key generation, and cryptographic accelerators for DES/3DES/AES/SHA-1/SHA-256 - all operating independently of the CPU core to maintain real-time responsiveness during encrypted communication or firmware updates.

FAQ

What is the maximum operating frequency of the MK64FX512VDC12 core?

The MK64FX512VDC12 features an ARM Cortex-M4 core rated for up to 120 MHz operation. This frequency is achievable with the internal PLL locked to a 3–32 MHz crystal or external clock source, and requires proper VDD regulation (1.71–3.6 V) and thermal management within the –40°C to +105°C ambient range. The MK64FX512VDC12 maintains full peripheral functionality including Ethernet and USB at this speed.

Does the MK64FX512VDC12 support crystal-less USB operation?

Yes, the MK64FX512VDC12 supports crystal-less USB full-speed and low-speed device operation using its internal 48 MHz IRC48M oscillator. This eliminates the need for an external 48 MHz crystal or oscillator, reducing BOM cost and PCB space. The MK64FX512VDC12 meets USB-IF electrical compliance requirements in this mode per its validated reference design (AN5015).

What is the SRAM capacity of the MK64FX512VDC12 and how is it allocated?

The MK64FX512VDC12 integrates 256 KB of on-chip SRAM, organized as a unified block accessible by the CPU and DMA. It supports configurable memory protection via the MPU and can be partitioned into cacheable/non-cacheable regions. This SRAM capacity enables real-time buffering of Ethernet frames, USB transactions, and sensor data streams without external memory - a key advantage of the MK64FX512VDC12 in latency-sensitive applications.

Which low-power modes does the MK64FX512VDC12 support and what is the lowest current draw?

The MK64FX512VDC12 supports seven low-power modes including VLLS0 (Very-Low-Leakage Stop 0), which achieves as low as 339 nA at 3.0 V with POR circuit disabled and full register retention. Wakeup occurs in 5 µs. Other modes include Stop (0.49 mA typical), VLPS (57 µA), and LLS (5.8 µA) - all verified across –40°C to +105°C. These capabilities make the MK64FX512VDC12 ideal for battery-backed industrial monitoring nodes.

Is the MK64FX512VDC12 pin-compatible with other K64 family members in the same package?

Yes, the MK64FX512VDC12 is pin-compatible with other K64 variants offered in the 144-pin LQFP package (e.g., MK64FN1M0VDC12, MK66FN2M0VLQ18), sharing identical mechanical footprint, power/ground pinout, and peripheral signal assignments. However, differences in flash size, FlexMemory configuration, and optional features require corresponding software and clock tree adjustments - the MK64FX512VDC12 remains electrically and physically interchangeable at board level.
