Product details
Overview
MKE14Z128VLL7 from NXP Semiconductors is an ARM® Cortex®-M0+ based microcontroller with 128 KB flash, 16 KB SRAM, and 100-pin LQFP package. It delivers up to 72 MHz operation, dual 12-bit 1 Msps ADCs (16+12 channels), three FlexTimer modules for PWM generation, and supports BLDC motor control and industrial HMI systems.
For engineers reviewing the MKE14Z128VLL7 datasheet, MKE14Z128VLL7 pinout, MKE14Z128VLL7 application, or MKE14Z128VLL7 equivalent, key selection criteria include its 72 MHz Cortex-M0+ core, 100-LQFP thermal performance (–40 to 105 °C), integrated TSI-free analog interface, and low-power peripheral set including LPUART×3, LPSPI×2, and LPI2C×2.
Technical Context
The MKE14Z128VLL7 implements a single ARMv6-M Thumb®-2 ISA compliant Cortex-M0+ core with nested vectored interrupt controller (NVIC), memory-mapped divide/square root (MMDVSQ), and 8-channel eDMA extended to 63 sources via DMAMUX. Its system clock generator (SCG) selects among FIRC (48–60 MHz ±1%), SIRC (2/8 MHz ±3%), OSC (4–40 MHz), OSC32 (32 kHz), and LPO (128 kHz).
Peripheral subsystems include two independent 12-bit SAR ADCs with hardware triggers from FTM/LPTMR/RTC/CMP, two analog comparators each with internal 8-bit DAC, three FlexTimers supporting deadtime insertion and fault inputs, and low-power communication interfaces (LPUART×3, LPSPI×2, LPI2C×2) all functional in VLPS mode with SIRC/OSC clocking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE15Z128VLL7 | Includes TSI module and additional GPIO interrupt sources; otherwise identical flash/SRAM/peripherals. | Required for capacitive touch HMI (e.g., dashboard controls); unnecessary if only discrete buttons/switches used. | Select MKE15Z128VLL7 only when TSI-based user interface is part of the design. |
| MKE14Z128VLH7 | Same core/peripherals but in 64-pin LQFP (10×10 mm); reduced GPIO count (58 vs. 89) and ADC channels (16+11 vs. 16+12). | Suitable for space-constrained designs where fewer I/O and one less ADC channel are acceptable. | Choose MKE14Z128VLH7 for compact PCB layouts where full 100-pin I/O is not required. |
Compared with MKE15Z128VLL7, the MKE14Z128VLL7 omits TSI for lower cost and simplified layout; compared with MKE14Z128VLH7, it provides 31 more GPIOs and one extra ADC channel in the same footprint class - making it optimal for I/O-intensive industrial control where touch is not needed.

The MKE14Z128VLL7 supports Run, Wait, Stop, Very Low Power Run (VLPR), Very Low Power Wait (VLPW), and Very Low Power Stop (VLPS) modes. In VLPS mode, peripherals including LPUART, LPSPI, LPI2C, ADC, CMP, RTC, and LPIT remain operational with SIRC or OSC clocking - enabling sub-10 µA sleep current with fast wake-up.
How much Flash and RAM does the MKE14Z128VLL7 have?
The MKE14Z128VLL7 integrates 128 KB of program flash memory, 16 KB of SRAM, 32 KB of FlexNVM for data flash and EEPROM emulation, and 2 KB of FlexRAM for additional EEPROM emulation - providing ample non-volatile storage for firmware, calibration data, and event logs without external memory.
Which communication interfaces are available on the MKE14Z128VLL7?
The MKE14Z128VLL7 features three low-power UARTs (LPUART0–2), two low-power SPIs (LPSPI0–1), two low-power I²Cs (LPI2C0–1), and a flexible serial interface module (FlexIO) - all with DMA support and VLPS-mode operation.
