NXP Semiconductors MK10DX32VLF5

Overview

MK10DX32VLF5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extension, designed for embedded control applications requiring real-time signal processing and low-power operation. It features 32 KB program flash, 16 KB RAM, 16-bit SAR ADC, three UARTs, SPI, I²C, and I²S interfaces, and operates from 1.71–3.6 V across –40 to 105°C ambient.

For engineers reviewing the MK10DX32VLF5 datasheet, MK10DX32VLF5 pinout, MK10DX32VLF5 application, or MK10DX32VLF5 equivalent, key selection considerations include its FlexMemory architecture (Flash + FlexNVM/FlexRAM), multi-mode power management (down to 0.176 µA in VLLS0), 50 MHz core performance, and LQFP-48 package compatibility with industrial motor control, sensor fusion, and battery-powered HMI designs.

Technical Context

The MK10DX32VLF5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC operations, delivering 1.25 Dhrystone MIPS per MHz at up to 50 MHz. Its clock system includes dual crystal oscillators (3–32 MHz and 32 kHz), MCG module supporting FEI/FBI/FBE/BLPE modes, and programmable delay block for precise timing control.

System-level integration includes a 4-channel DMA controller servicing 41 request sources, hardware CRC engine, 128-bit unique chip ID, and analog subsystem comprising two comparators with integrated 6-bit DACs and voltage reference. Low-power operation is enabled via eight distinct run/stop/low-leakage modes, including VLLS0 with POR detect circuit disabled.

FAQ

What is the maximum operating frequency of the MK10DX32VLF5?

The MK10DX32VLF5 operates at a maximum system and core clock frequency of 50 MHz. This is achieved using the internal MCG clock generator in FEI or FBE mode with an external crystal, or in BLPE mode for low-power operation. The 50 MHz rating is guaranteed across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage, enabling deterministic real-time performance in industrial control loops.

Does the MK10DX32VLF5 include FlexMemory functionality?

No, the MK10DX32VLF5 does not include FlexMemory. Per the K10 part numbering scheme, the "X" denotes FlexMemory capability (program flash + FlexNVM/FlexRAM), but the MK10DX32VLF5 variant is specified with 32 KB program flash only and no FlexNVM or FlexRAM. FlexMemory is present in higher-density variants like MK10DX64VLF5 and MK10DX128VLF5, but not in the 32 KB version.

What package type and pin count does the MK10DX32VLF5 use?

The MK10DX32VLF5 uses a 48-pin LQFP package (7 mm × 7 mm), identified by the "LF" suffix in the part number. This package provides full access to all GPIO, analog, and communication peripherals, supports standard reflow soldering, and is rated MSL3 for moisture sensitivity. Pin assignments follow the K10 Sub-Family pinout specification, with dedicated VDDA/VSSA pins for analog domain isolation.

Can the MK10DX32VLF5 operate from a single 1.8 V supply?

Yes, the MK10DX32VLF5 supports operation from 1.71 V to 3.6 V, including 1.8 V nominal supplies. At 1.8 V, it maintains full functionality at reduced maximum frequency (verified up to 40 MHz), with typical run-mode current of 13.7 mA and VLPR-mode current of 867 µA. All I/Os remain 5 V tolerant only when VDD ≥ 2.3 V; below that, input thresholds scale with VDD per the VIH/VIL specifications.

What debug interface does the MK10DX32VLF5 support?

The MK10DX32VLF5 supports SWD (Serial Wire Debug) via dedicated SWDIO and SWCLK pins, compliant with ARM CoreSight standards. It does not include JTAG support. Debugging is enabled through the OpenSDA interface on compatible NXP evaluation boards (e.g., FRDM-K10DX128), and the device supports flash programming via EzPort or the built-in ROM bootloader using UART or USB HID protocols.
