Product details
Overview
MKE17Z256VLL7 from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 256 KB flash, 48 KB SRAM, and integrated analog peripherals including a 12-bit 1 Msps ADC, three FlexTimers (FTM), and dual TSI modules for touch sensing - deployed in industrial motor control and HMI systems.
For engineers reviewing the MKE17Z256VLL7 datasheet, MKE17Z256VLL7 pinout, MKE17Z256VLL7 application, or MKE17Z256VLL7 equivalent, key selection criteria include low-power operation across VLPR/VLPS modes, 89 GPIOs with high-drive capability, LPUART/LPSPI/LPI2C serial interfaces with DMA support, and robust wake-up capability from Stop mode via AWIC.
Technical Context
The MKE17Z256VLL7 implements a tightly coupled ARMv6-M architecture with Thumb-2 ISA, configurable NVIC supporting 32 interrupt vectors and 4 priority levels, and an eDMA controller extended to 63 channels via DMAMUX for efficient peripheral-to-memory transfers without CPU intervention.
Its clock system integrates SCG with multiple sources - FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), LPO (128 kHz), LPFLL, and external crystal (4–40 MHz) - enabling dynamic switching between Run, Wait, Stop, VLPR, VLPW, and VLPS modes while maintaining peripheral functionality such as ADC, CMP, LPTMR, and LPUART in VLPS.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE17Z256VLH7 | 64-pin LQFP, 58 GPIOs, 47 TSI channels - same core, memory, and peripheral set but reduced I/O count and package size. | Suitable for space-constrained designs where full 89 GPIOs and 50 TSI channels are unnecessary. | Select when board area is limited and HMI complexity is reduced (e.g., 4-button panel vs. 12-button + slider). |
| MKE13Z256VLL7 | Same 100-LQFP package and pinout, but only 25-channel TSI - otherwise identical flash/SRAM/peripherals except reduced touch channel count. | Targeted at cost-sensitive motor control applications requiring full GPIO count but minimal touch interface. | Choose when touch sensing is secondary (e.g., single power-on slider) and budget constraints favor lower-tier KE13Z series pricing. |
Compared with MKE17Z256VLL7, the VLH7 variant trades I/O density for compactness while retaining full peripheral functionality, whereas the MKE13Z256VLL7 offers identical mechanical compatibility but reduced TSI capacity - making both viable alternatives depending on whether layout area or touch channel count is the dominant constraint.

FAQ
What is the maximum operating frequency of the MKE17Z256VLL7?
The MKE17Z256VLL7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This maximum frequency is achievable using the 48 MHz FIRC clock source with PLL multiplication or external crystal oscillator input, subject to voltage and temperature conditions specified in the electrical characteristics table. The MKE17Z256VLL7 maintains full peripheral functionality at this speed, including ADC sampling and FTM PWM generation.
Does the MKE17Z256VLL7 support hardware debugging?
Yes, the MKE17Z256VLL7 includes Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, enabling full run-control, breakpoint setting, register inspection, and Micro Trace Buffer (MTB) trace capture. Debug access remains functional across all power modes except when security is enabled via flash configuration field 0x40E, which disables SWD memory access while preserving mass-erase capability.
How many analog-to-digital converter channels does the MKE17Z256VLL7 have?
The MKE17Z256VLL7 integrates one 12-bit successive approximation register (SAR) ADC module with up to 16 single-ended analog input channels. These channels are mapped to dedicated pins (ADC0_SE0 through ADC0_SE15) and support hardware triggering from FTM, LPTMR, PIT, external pins, or comparator outputs - enabling precise synchronization for motor current sampling and sensor acquisition.
What low-power modes are supported by the MKE17Z256VLL7?
The MKE17Z256VLL7 supports six distinct power modes: Run, Wait, Stop, Very Low Power Run (VLPR), Very Low Power Wait (VLPW), and Very Low Power Stop (VLPS). In VLPS mode, the MCU draws sub-10 μA while retaining SRAM content and enabling wake-up via ADC, CMP, LPUART, LPTMR, or GPIO - verified per NXP's KE1xZP100M72SF1 datasheet Rev. 2.2.
Is the MKE17Z256VLL7 pin-compatible with other KE1xZ family members?
The MKE17Z256VLL7 uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) and shares identical pinout with MKE17Z128VLL7, MKE13Z256VLL7, and MKE12Z256VLL7 - confirmed in NXP's KE1xZ Signal Multiplexing and Pin Assignments documentation. This allows direct PCB reuse across flash/RAM variants and feature subsets within the same package footprint.
