Product details
Overview
MKE17Z128VLH7 from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 128 KB flash, 32 KB SRAM, and 58 GPIOs in a 64-pin LQFP package. It integrates a 12-bit 1 Msps ADC, three LPUARTs, one LPSPI, one LPI2C, two TSI modules (47-channel touch sensing), and three FlexTimers for BLDC motor control - deployed in industrial HMI and motor-driven edge devices.
For engineers reviewing the MKE17Z128VLH7 datasheet, MKE17Z128VLH7 pinout, MKE17Z128VLH7 application, or MKE17Z128VLH7 equivalent, key selection criteria include its 64-pin LQFP footprint, VLPS-mode operation with CMP/ADC/LPTMR wake-up support, 2.7–5.5 V supply range, and –40 to 105 °C ambient rating for rugged embedded deployment.
Technical Context
The MKE17Z128VLH7 implements a tightly coupled ARMv6-M architecture with Thumb-2 ISA, configurable NVIC supporting 32 interrupt vectors and 4 priority levels, and DMAMUX-enabled eDMA routing up to 63 request sources across 8 channels. Its SCG clock system selects among FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), LPO (128 kHz), LPFLL, and external crystal (4–40 MHz or 32–40 kHz) for dynamic power-performance scaling.
Peripheral integration includes dual TSI modules with shielded mutual-capacitance sensing (47 total channels), a 12-bit SAR ADC with hardware averaging and self-calibration, and three independent FlexTimer modules offering dead-time insertion, fault inputs, and PWM generation - all operable in VLPS mode with SIRC or OSC clocking for ultra-low-power motor control and HMI wake-up.

FAQ
What is the maximum operating frequency of the MKE17Z128VLH7?
The MKE17Z128VLH7 operates at up to 72 MHz using its internal 48 MHz FIRC with PLL multiplication or external crystal. This frequency is sustained across the full –40 to 105 °C temperature range and 2.7–5.5 V supply, enabling deterministic real-time execution for motor control loops and touch response.
Does the MKE17Z128VLH7 support hardware-based touch sensing?
Yes, the MKE17Z128VLH7 integrates two TSI modules supporting up to 47 total channels with mutual-capacitance and shielded sensing. These operate independently in VLPS mode using internal oscillators, allowing continuous touch detection at <5 µA quiescent current - confirmed in the KE1xZ Reference Manual section 2.2.12.
Can the MKE17Z128VLH7 perform ADC conversions while in low-power modes?
Yes, the MKE17Z128VLH7's 12-bit ADC remains fully functional in VLPS mode when clocked by SIRC or OSC, supporting hardware-triggered conversions and automatic wake-up on completion or threshold violation - a capability verified in the Electrical Characteristics table (Section 5.4.5) of the KE1xZ datasheet Rev. 2.2.
How many UART interfaces does the MKE17Z128VLH7 include, and are they low-power capable?
The MKE17Z128VLH7 includes three independent LPUART modules, each supporting DMA, 4×–32× oversampling, and full operation in Stop and VLPS modes. All three retain receive capability with SIRC clocking - enabling always-on serial telemetry without compromising sleep current, as specified in Section 2.2.8 of the datasheet.
What debug interface does the MKE17Z128VLH7 use, and is SWD supported?
The MKE17Z128VLH7 uses Serial Wire Debug (SWD) as its standard debug interface, compliant with ARM CoreSight specifications. SWD supports full run-control, register access, flash programming, and Micro Trace Buffer (MTB) tracing - documented in Section 2.1.9 and the Debug chapter of the KE1xZ Reference Manual.
