NXP Semiconductors MK30DX128VLK7

Overview

MK30DX128VLK7 from NXP Semiconductors (formerly Freescale) is a Kinetis K30-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, CAN, four UARTs, and low-power timers - deployed in industrial motor control and smart sensor nodes.

For engineers reviewing the MK30DX128VLK7 datasheet, MK30DX128VLK7 pinout, MK30DX128VLK7 application, or MK30DX128VLK7 equivalent, key selection criteria include its 72 MHz max CPU frequency, FlexMemory support, CAN 2.0B compliance, segmented LCD controller capability, and verified VLLS1/VLLS2 sub-μA stop-mode operation under 3.0 V.

Technical Context

The MK30DX128VLK7 implements a multi-clock architecture with MCG supporting FEE/FBE/BLPE modes, enabling dynamic clock scaling between 4 MHz (VLPR) and 72 MHz (RUN). Its system-level power management includes eight low-power modes (VLPS, LLS, VLLS1–VLLS3), each with distinct wake-up sources and current profiles validated down to 1.47 μA in VLLS1 at –40 to 25°C.

Peripherals are partitioned into always-on (RTC, LPUART, TSI) and domain-gated blocks. The FlexCAN module uses an external reference clock up to 8 MHz and supports programmable bit timing; the dual ADCs share a common voltage reference and support hardware-triggered conversions with 12-bit DAC-assisted comparison.

FAQ

What is the maximum operating frequency of the MK30DX128VLK7?

The MK30DX128VLK7 supports a maximum system and core clock frequency of 72 MHz in FEE mode, achieved using the internal MCG with an external 8–32 MHz crystal. At this speed, the device delivers 115 DMIPS performance while maintaining full peripheral functionality and validated timing margins per the K30P81M72SF1 datasheet Rev. 3.

Does the MK30DX128VLK7 include a hardware floating-point unit (FPU)?

No, the MK30DX128VLK7 implements the ARM Cortex-M4 core with DSP extensions but does not include a hardware FPU. Floating-point operations must be handled in software or via CMSIS-DSP library functions. This design choice reduces die size and power consumption, aligning with the K30 family's focus on deterministic real-time control over general-purpose computation.

Can the MK30DX128VLK7 operate from a single 3.3 V supply across all peripherals?

Yes, the MK30DX128VLK7 operates from a single 1.71–3.6 V supply for both digital (VDD) and analog (VDDA) domains, with a maximum differential of ±0.1 V between them. All I/Os are 5 V tolerant, and the internal voltage reference (VBG = 1.00 V ±30 mV) remains stable across voltage and temperature - enabling robust operation from standard 3.3 V rails without external regulators.

What low-power modes are supported by the MK30DX128VLK7, and what is the lowest achievable current?

The MK30DX128VLK7 supports eight low-power modes, including VLLS1, VLLS2, and VLLS3. In VLLS1 mode at 3.0 V and –40 to 25°C, the device achieves 1.47 μA typical current with RTC running and selected GPIOs enabled. This is validated in the K30P81M72SF1 datasheet Table 6 and enables decade-long battery life in intermittent-sensing applications.

Is the MK30DX128VLK7 pin-compatible with other K30 family members like MK30DX256VLK7?

Yes, the MK30DX128VLK7 and MK30DX256VLK7 share identical 80-pin LQFP (LK) packaging, pin assignments, and signal multiplexing. They are hardware-compatible drop-in replacements - differing only in flash size (128 KB vs. 256 KB) and FlexMemory configuration - allowing seamless migration during development or production scaling without PCB redesign.
