NXP Semiconductors MK10DX128VLK7

Overview

MK10DX128VLK7 from NXP Semiconductors (formerly Freescale) is a Kinetis K10-series ARM Cortex-M4 microcontroller with DSP extension, 128 KB flash, 16 KB SRAM, and 80-pin LQFP package. It operates from 1.71–3.6 V across –40 to 105°C, integrates dual 16-bit SAR ADCs with PGA, 12-bit DAC, CAN, four UARTs, and real-time clock - deployed in industrial motor control and smart sensor edge nodes.

For engineers reviewing the MK10DX128VLK7 datasheet, MK10DX128VLK7 pinout, MK10DX128VLK7 application, or MK10DX128VLK7 equivalent, key selection criteria include its 72 MHz max core frequency, low-leakage stop modes (as low as 1.47 µA), integrated TSI for touch interfaces, FlexCAN compliance, and support for deterministic real-time control in resource-constrained embedded systems.

Technical Context

The MK10DX128VLK7 implements a 32-bit ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, paired with a multi-purpose clock generator supporting crystal oscillators at 3–32 MHz and 32 kHz. Its memory subsystem includes 128 KB on-chip flash with error correction, 16 KB SRAM, and FlexMemory for EEPROM emulation.

Peripherals are orchestrated via an AHB/APB bus matrix with 16-channel DMA supporting up to 63 request sources. Power management leverages eight low-power modes including VLLS1–VLLS3, enabling sub-2 µA retention with RTC and wakeup logic active - critical for battery-backed industrial monitoring.

FAQ

What is the maximum operating frequency of the MK10DX128VLK7?

The MK10DX128VLK7 supports a maximum core clock frequency of 72 MHz in normal run mode, achieved via its internal PLL or FLL. This frequency is validated across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage. The MK10DX128VLK7 maintains timing compliance for all peripherals-including CAN, ADC, and PWM-at this speed when configured per the MCG and clock gating specifications in the K10P81M72SF1 datasheet.

Does the MK10DX128VLK7 include hardware security features?

Yes, the MK10DX128VLK7 includes a hardware CRC module for fast cyclic redundancy checks and a factory-programmed 128-bit unique identification number per chip. While it lacks dedicated cryptographic accelerators or TrustZone, these features support firmware integrity validation and device identity binding. The MK10DX128VLK7 does not integrate AES, SHA, or secure boot engines - those capabilities appear in later Kinetis families like K2x or LPC55xx.

Can the MK10DX128VLK7 operate from a single 3.3 V supply?

Yes, the MK10DX128VLK7 operates fully within its specified 1.71–3.6 V supply range, making 3.3 V a valid and commonly used VDD voltage. At 3.3 V, the MK10DX128VLK7 achieves its rated 72 MHz performance, supports all I/O drive strengths, and meets ADC/DAC accuracy specs. Ensure VDDA is tied to the same 3.3 V rail (with appropriate decoupling) and that VDD–VDDA differential remains within ±0.1 V per datasheet Section 5.2.1.

What low-power modes are supported by the MK10DX128VLK7?

The MK10DX128VLK7 supports eight low-power modes: RUN, WAIT, VLPR, STOP, VLPS, LLS, and three VLLS variants (VLLS0–VLLS3). The deepest retention mode is VLLS3, drawing as little as 1.47 µA at –40 to 25°C while retaining RAM, RTC, and wakeup logic. All modes are controlled via the System Mode Controller (SMC) and require specific clock gating and peripheral disable sequences documented in the K10P81M72SF1 reference manual.

Is the MK10DX128VLK7 pin-compatible with other Kinetis K10 devices?

The MK10DX128VLK7 shares the 80-pin LQFP (LK) package footprint and pin assignment with MK10DX256VLK7 and MK10DX64VLK7 - confirmed by K10 Sub-Family Data Sheet Rev. 3, Section 8.2. Pin functions are identical across these variants; only flash size and associated memory-mapped registers differ. However, it is not pin-compatible with K10 devices in other packages (e.g., LF, LH, or MC) or with K20/K60 series microcontrollers.
