NXP Semiconductors MK10DX128VLK7R

Overview

MK10DX128VLK7R 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, low-power operation, and integrated analog peripherals. It features 128 KB flash, 16 KB SRAM, operates from 1.71–3.6 V, supports –40 to 105°C ambient temperature, and integrates dual 16-bit SAR ADCs with PGA, 12-bit DAC, CAN, UART, I²C, SPI, and I²S interfaces.

For engineers reviewing the MK10DX128VLK7R datasheet, MK10DX128VLK7R pinout, MK10DX128VLK7R application, or MK10DX128VLK7R equivalent, key selection considerations include its 72 MHz max CPU frequency, 80-pin LQFP package, integrated TSI touch interface, hardware CRC module, and support for multiple low-power stop modes down to 1.47 µA in VLLS1 mode.

Technical Context

The MK10DX128VLK7R implements the ARMv7E-M architecture with Harvard bus interface, nested vectored interrupt controller (NVIC), and memory protection unit (MPU). Its clock system includes a multi-purpose clock generator (MCG) supporting FEE, FEI, BLPE, and PBE modes, enabling flexible configuration of internal and external oscillators (3–32 MHz main, 32 kHz RTC).

Peripherals are organized into functional domains: analog subsystem (dual ADCs with programmable gain up to ×64, 12-bit DAC, three comparators with 6-bit DAC reference), timing (eight-channel TPM, two quadrature decoder timers, RTC, LPTMR), and communication (one FlexCAN module, four UARTs, two SPIs, two I²Cs, one I²S). All modules are accessible via AHB/APB bridges with configurable clock gating.

FAQ

What is the maximum operating frequency of the MK10DX128VLK7R?

The MK10DX128VLK7R has a maximum CPU frequency of 72 MHz, achieved using the MCG in FEE mode with an external 32 MHz crystal and internal PLL. This frequency is fully supported across the entire –40 to 105°C temperature range and 1.71–3.6 V supply voltage, delivering 115 DMIPS of performance for real-time control tasks. The MK10DX128VLK7R's bus and flash clocks scale accordingly to maintain timing compliance.

Does the MK10DX128VLK7R include a hardware floating-point unit (FPU)?

No, the MK10DX128VLK7R implements the ARM Cortex-M4 core with DSP extensions but does not include a hardware floating-point unit (FPU). It supports integer and fixed-point arithmetic natively, and the DSP instruction set accelerates common operations like multiply-accumulate (MAC) and saturating arithmetic. For applications requiring IEEE-754 floating-point computation, alternative parts such as the Kinetis K22 or STM32F4 series should be considered. The MK10DX128VLK7R remains optimized for deterministic, low-latency control where fixed-point efficiency is preferred.

What low-power modes are supported by the MK10DX128VLK7R, and what is the lowest achievable current?

The MK10DX128VLK7R supports seven low-power modes: RUN, WAIT, STOP, VLPS, LLS, VLLS0–VLLS3. The lowest active current is 1.47 µA in VLLS1 mode at –40 to 25°C with RTC disabled and only LLWU wake sources enabled. In VLLS3 mode with RTC running from 32 kHz crystal, typical current is 1.9 µA. These modes are controlled via the SMC module and require specific clock gating and peripheral disable sequences. The MK10DX128VLK7R's power management is validated per the K10P81M72SF1 datasheet Rev. 3.

Can the MK10DX128VLK7R directly interface with a 5 V peripheral?

No, the MK10DX128VLK7R is not 5 V tolerant. Its digital I/O pins operate at 1.71–3.6 V and have absolute maximum ratings of –0.3 V to VDD + 0.3 V (max 3.9 V). Direct connection to 5 V logic will exceed voltage ratings and risk permanent damage. Level translation is required-for example, using discrete MOSFET translators or dedicated bidirectional level shifters such as the TXS0108E. The MK10DX128VLK7R's datasheet explicitly prohibits exceeding VIO = 3.6 V under any condition.

How many analog-to-digital converter (ADC) channels does the MK10DX128VLK7R provide, and what is their resolution?

The MK10DX128VLK7R integrates two independent 16-bit successive approximation register (SAR) ADCs: ADC0 and ADC1. Each supports up to 16 single-ended or 8 differential input channels, with built-in programmable gain amplifiers (PGA) offering gains of ×1, ×2, ×4, ×8, ×16, ×32, or ×64. Conversion time is as low as 1.0 µs per sample at maximum clock rate. Both ADCs can operate simultaneously, enabling synchronized sampling for motor phase current measurement. This ADC capability is documented in the K10P81M72SF1 datasheet Section 6.6.1.
