Product details
Overview
MKE17Z256VLH7 from NXP Semiconductors is a 64-pin LQFP ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 256 KB flash, 48 KB SRAM, and integrated 12-bit 1 Msps ADC - deployed in BLDC motor control, industrial HMI, and low-power sensor nodes.
For engineers reviewing the MKE17Z256VLH7 datasheet, MKE17Z256VLH7 pinout, MKE17Z256VLH7 application, or MKE17Z256VLH7 equivalent, key selection criteria include its 58 GPIOs with high-drive capability, dual TSI modules for robust touch sensing, and full low-power peripheral operation (LPUART/LPSPI/LPI2C/ADC/CMP) in VLPS mode.
Technical Context
The MKE17Z256VLH7 implements an ARMv6-M architecture with Thumb®-2 ISA, configurable NVIC supporting 32 interrupt vectors and 4 priority levels, and a crossbar switch enabling concurrent bus master access. Its SCG clock system integrates FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), LPO (128 kHz), LPFLL, and external crystal support (4–40 MHz).
Power management is handled by PMC with six operational modes (Run, Wait, Stop, VLPR, VLPW, VLPS); peripherals like ADC, CMP, LPTMR, LPIT, FlexIO, and all three LPUARTs remain functional in VLPS mode using SIRC or OSC clocks. The device includes eDMA (8 channels, extended to 63 via DMAMUX) and hardware CRC-16/32 for data integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE17Z256VLL7 | 100-pin LQFP, 89 GPIOs, 50 TSI channels - larger package, higher I/O count, same core/peripherals. | Required when >58 GPIOs or >47 TSI channels needed; unsuitable for space-constrained 64-pin layouts. | Select MKE17Z256VLL7 only if board redesign accommodates 100-pin footprint and additional routing complexity. |
| MKE13Z256VLH7 | Same 64-pin LQFP, but reduced TSI (22 channels) and no temperature sensor - lower-cost variant in same family. | Suitable for non-touch applications or where thermal monitoring is not required; lacks TSI shielding capability. | Choose MKE13Z256VLH7 for cost-sensitive motor control without HMI, but verify TSI channel count suffices for target interface. |
Compared with MKE17Z256VLH7, the VLL7 offers greater I/O scalability at the cost of board area, while the MKE13Z256VLH7 trades TSI capability and thermal sensing for lower unit cost - both require validation of peripheral feature alignment before drop-in use.

FAQ
What is the maximum operating frequency of the MKE17Z256VLH7?
The MKE17Z256VLH7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This maximum frequency is achievable when powered within the specified 2.7–5.5 V supply range and operating within the –40 to 105 °C ambient temperature range. The system clock is derived from the SCG module using sources such as the 48 MHz FIRC or external crystal, with appropriate dividers configured in software. MKE17Z256VLH7 maintains full peripheral functionality at this speed, including ADC sampling at 1 Msps and FTM PWM generation.
Does the MKE17Z256VLH7 support hardware debugging during development?
Yes, the MKE17Z256VLH7 includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, enabling full run-control, register inspection, memory access, and basic trace via Micro Trace Buffer (MTB). Debug is accessible through standard tools like MCUXpresso IDE and J-Link probes. Note that security can be enabled via flash configuration field 0x40E, which disables SWD memory access - MKE17Z256VLH7 retains debug port functionality for mass erase even when secured.
How many analog-to-digital converter channels does the MKE17Z256VLH7 provide?
The MKE17Z256VLH7 integrates one 12-bit successive approximation register (SAR) ADC module supporting up to 16 single-ended analog input channels. These channels are mapped to dedicated pins (e.g., ADC0_SE0 through ADC0_SE15) and can be triggered by hardware sources including FTM, LPTMR, LPIT, CMP output, or external pins. MKE17Z256VLH7 also includes an on-die temperature sensor connected to ADC channel AD26 for system thermal monitoring.
Can the MKE17Z256VLH7 operate in ultra-low-power modes while retaining peripheral functionality?
Yes, the MKE17Z256VLH7 supports Very Low Power Stop (VLPS) mode where the core and most peripherals are disabled, yet critical functions remain active: ADC, CMP, LPUART×3, LPSPI, LPI2C, LPIT, LPTMR, FlexIO, and DMA. These peripherals operate using SIRC or OSC clocks, enabling wake-on-event capabilities with sub-5 µs latency. MKE17Z256VLH7 achieves typical VLPS current draw of 2.5 µA - making it suitable for battery-powered applications requiring long-term standby with responsive wake behavior.
What touch sensing capability does the MKE17Z256VLH7 offer?
The MKE17Z256VLH7 includes two independent Touch Sense Interface (TSI) modules supporting a total of 47 touch channels - 25 on TSI0 and 22 on TSI1 - optimized for mutual capacitance scanning with shield channel support. Each TSI module provides hardware-accelerated noise filtering, automatic baseline tracking, and ESD-tolerant input structure. MKE17Z256VLH7's TSI implementation meets IEC 61000-4-2 Level 4 (±8 kV contact) without external protection components, making it ideal for rugged industrial touch panels.
