Overview
MKE15Z256VLH7R from NXP Semiconductors is a 64-pin LQFP ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 256 KB flash, 32 KB SRAM, and dual 12-bit 1 Msps ADCs - deployed in BLDC motor control systems with integrated FlexTimer PWM generation and robust TSI for HMI touch sensing.
For engineers reviewing the MKE15Z256VLH7R datasheet, MKE15Z256VLH7R pinout, MKE15Z256VLH7R application, or MKE15Z256VLH7R equivalent, key selection criteria include its 64-LQFP package, 58 GPIOs (8 high-drive), 16+11 ADC channels, TSI support, and low-power operation across VLPR/VLPS modes - critical for cost-sensitive industrial motor drives and embedded HMI designs.
Technical Context
The MKE15Z256VLH7R implements an ARMv6-M Thumb®-2 ISA core with configurable NVIC, MMDVSQ for integer divide/sqrt, and eDMA with DMAMUX routing up to 63 request sources across 8 channels. Its SCG clock generator supports FIRC (±1% @ 48–60 MHz), SIRC (±3%), OSC32, and LPFLL for flexible low-power timing.
Analog subsystem includes two independent 12-bit SAR ADCs (1 Msps, hardware-triggered by FTM/LPTMR/RTC), dual comparators each with integrated 8-bit DAC and rail-to-rail inputs, and TSI supporting up to 25 channels with high-noise immunity. Power management enables VLPS mode with CMP, ADC, LPUART, LPI2C, and LPIT active using SIRC/OSC32 clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE15Z256VLL7 | 100-pin LQFP, 89 GPIOs, 16+12 ADC channels, same core/peripherals - larger package with more I/O and ADC inputs. | Better suited for complex motor drives requiring >58 GPIOs or additional analog inputs (e.g., dual shunt + bus voltage). | Select when board layout accommodates 100-LQFP and higher I/O count is needed; otherwise MKE15Z256VLH7R offers identical performance in smaller footprint. |
| MKE14Z256VLH7 | Same 64-LQFP package and peripherals, but lacks TSI module - no touch sensing capability. | Applicable where HMI is button-based or absent, reducing cost in pure motor control or metering roles. | Choose only if TSI is unnecessary; MKE15Z256VLH7R adds touch functionality without sacrificing performance or power efficiency. |
Compared with MKE15Z256VLL7, the MKE15Z256VLH7R saves PCB area and assembly cost while retaining full analog/timing/peripheral capability; versus MKE14Z256VLH7, it adds production-ready TSI for next-gen HMI without increasing power or complexity.

FAQ
What is the maximum operating frequency of the MKE15Z256VLH7R?
The MKE15Z256VLH7R operates at up to 72 MHz using the FIRC clock source (±1% accuracy). This frequency is achievable in RUN and VLPR modes, with automatic clock scaling when entering low-power states like VLPS to maintain timing integrity while minimizing current draw. The MKE15Z256VLH7R's SCG module ensures seamless transitions between clock sources without software intervention.
Does the MKE15Z256VLH7R support hardware-accelerated division or square root operations?
Yes, the MKE15Z256VLH7R includes a Memory-Mapped Divide and Square Root (MMDVSQ) module that executes 32-bit signed/unsigned integer division and square root in fixed cycles - offloading computationally intensive tasks from the Cortex-M0+ core. This feature is directly accessible via memory-mapped registers and improves real-time determinism in motor control math routines within the MKE15Z256VLH7R firmware.
How many ADC channels does the MKE15Z256VLH7R support, and are they simultaneous?
The MKE15Z256VLH7R integrates two independent 12-bit SAR ADC modules: ADC0 supports 16 single-ended inputs, ADC1 supports 11 - totaling 27 analog input channels. While not truly simultaneous, both ADCs can be triggered synchronously via FTM or PDB, enabling tightly coordinated sampling for multi-axis current sensing. Each ADC achieves up to 1 Msps conversion rate with hardware averaging and self-calibration enabled in the MKE15Z256VLH7R.
Can the MKE15Z256VLH7R operate in ultra-low-power modes while maintaining serial communication?
Yes, the MKE15Z256VLH7R supports full LPUART, LPSPI, and LPI2C operation in VLPS mode using the SIRC (8 MHz) or OSC32 (32.768 kHz) clock sources. These interfaces retain DMA capability and interrupt-driven receive/transmit functionality without waking the Cortex-M0+ core - allowing background data exchange at <20 μA system current. This behavior is verified in the MKE15Z256VLH7R electrical characteristics table (Section 5.4.6).
Is the MKE15Z256VLH7R pin-compatible with other KE1xZ variants?
The MKE15Z256VLH7R shares identical pinout and signal mapping with all KE1xZ devices in the 64-LQFP (LH) package, including MKE14Z256VLH7 and MKE15Z128VLH7. This allows direct substitution within the same footprint for memory or feature scaling - provided software accounts for differences in flash size, TSI presence, or peripheral enablement. Pin compatibility is confirmed in NXP document 98ASS23234W for the MKE15Z256VLH7R.
