Product details
Overview
MKE15Z128VLH7 from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller with 128 KB flash, 16 KB SRAM, and 64-pin LQFP package. It delivers up to 72 MHz operation, dual 12-bit 1 Msps ADCs (16+11 channels), and integrated TSI for robust touch sensing - enabling compact BLDC motor control and industrial HMI systems.
For engineers reviewing the MKE15Z128VLH7 datasheet, MKE15Z128VLH7 pinout, MKE15Z128VLH7 application, or MKE15Z128VLH7 equivalent, key selection criteria include its 64-pin LQFP footprint, 58 GPIOs (8 high-drive), FlexNVM for EEPROM emulation, low-power LPUART/LPSPI/LPI2C interfaces, and support for VLPS/Stop mode wake-up via CMP, RTC, or TSI.
Technical Context
The MKE15Z128VLH7 implements a single-core ARM Cortex-M0+ executing Thumb-2 instructions at up to 72 MHz, with NVIC supporting 32 interrupt vectors and 4 priority levels. Its system clock generator (SCG) selects among FIRC (48–60 MHz ±1%), SIRC (2/8 MHz ±3%), OSC32 (32 kHz), and external oscillators (4–40 MHz).
Peripheral integration includes three FlexTimer modules (FTM) with deadtime insertion for motor control, two 12-bit SAR ADCs with hardware-triggered conversions and self-calibration, and a dedicated TSI module supporting up to 25 touch channels - all operating in VLPS mode with SIRC or OSC32 clock sources.

FAQ
What is the maximum operating frequency of the MKE15Z128VLH7?
The MKE15Z128VLH7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This frequency is achievable using the 48–60 MHz FIRC clock source with appropriate SCG configuration and voltage supply (≥3.0 V). At lower voltages (2.7–3.0 V), the maximum safe frequency is reduced to 48 MHz per electrical specifications in the KE1xZP100M72SF0 datasheet.
Does the MKE15Z128VLH7 support EEPROM emulation, and how is it implemented?
Yes, the MKE15Z128VLH7 supports EEPROM emulation via 32 KB of FlexNVM and 2 KB of FlexRAM. The FlexNVM provides data flash with wear-leveling algorithms, while FlexRAM serves as a fast read/write buffer - both managed by NXP's Kinetis SDK EEPROM driver. This eliminates need for external EEPROM in applications like parameter storage or event logging.
Can the MKE15Z128VLH7 operate in ultra-low-power modes with analog peripherals active?
Yes, the MKE15Z128VLH7 supports VLPS mode with ADC, CMP, RTC, LPTMR, and TSI fully operational using SIRC or OSC32 clocks. In this state, typical current consumption is <2.5 µA while retaining wake-up capability from analog events - verified in Section 5.4.7 of the KE1xZP100M72SF0 datasheet.
What debug interface does the MKE15Z128VLH7 use, and is SWD supported?
The MKE15Z128VLH7 uses Serial Wire Debug (SWD) as its primary debug interface, compliant with ARM CoreSight standards. SWD is supported via dedicated SWDIO and SWCLK pins (PTA2 and PTA1), enabling full run-control, register access, and flash programming using standard tools like J-Link, LPC-Link2, or OpenSDA debug probes.
Is the MKE15Z128VLH7 pin-compatible with other KE1xZ variants in the same package?
Yes, the MKE15Z128VLH7 is pin-compatible with MKE15Z256VLH7, MKE14Z128VLH7, and MKE14Z256VLH7 in the 64-pin LQFP (LH) package. All share identical pin functions, electrical characteristics, and thermal profiles - allowing drop-in replacement for memory or feature scaling without PCB revision.
