Product details
Overview
MKE17Z128VLF7 from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 128 KB flash, 32 KB SRAM, and 42 GPIOs in a 48-pin LQFP package. It integrates a 12-bit 1 Msps ADC, three LPUARTs, one LPSPI, one LPI2C, two TSI modules (31 touch channels), and low-power timers (LPIT, LPTMR) for motor control and HMI applications.
For engineers reviewing the MKE17Z128VLF7 datasheet, MKE17Z128VLF7 pinout, MKE17Z128VLF7 application, or MKE17Z128VLF7 equivalent, key selection criteria include its 48-LQFP footprint, 2.7–5.5 V operation, –40 to 105 °C temperature range, and support for VLPS/Stop mode wake-up via CMP, ADC, LPUART, and TSI - critical for battery-powered industrial sensors and BLDC motor drives.
Technical Context
The MKE17Z128VLF7 implements a tightly coupled 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 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) sources.
Power management uses PMC to manage six operational modes (Run, Wait, Stop, VLPR, VLPW, VLPS), with AWIC handling asynchronous wake-up from Stop/VLPS using CMP, ADC, LPUART, LPSPI, LPI2C, LPIT, LPTMR, FlexIO, or TSI. All analog peripherals - including the 12-bit ADC with self-calibration and CMP with integrated 8-bit DAC - remain functional in VLPS mode with SIRC or OSC clocking.

FAQ
What is the maximum operating frequency of the MKE17Z128VLF7?
The MKE17Z128VLF7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This frequency is achievable using the 48 MHz Fast IRC (FIRC) with PLL multiplication or external crystal sources. The device maintains full peripheral functionality-including ADC sampling at 1 Msps and FTM PWM generation-at this maximum clock rate, validated across the full –40 to 105 °C temperature range.
Does the MKE17Z128VLF7 support hardware debugging?
Yes, the MKE17Z128VLF7 includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, supporting full run-control, breakpoints, watchpoints, and Micro Trace Buffer (MTB) for instruction trace. Debug access remains available in Run, Wait, and VLPR modes; however, SWD memory access is disabled when security is enabled via the flash configuration field at address 0x40e.
How many analog-to-digital converter channels does the MKE17Z128VLF7 provide?
The MKE17Z128VLF7 integrates one 12-bit SAR ADC module with 11 single-ended external input channels (ADC0_SE0 through ADC0_SE10), plus an internal temperature sensor channel. Channel selection is software-configurable via the ADCx_SC1 register, and conversions can be triggered by FTM, LPTMR, LPIT, external pins, or CMP output - enabling synchronized sampling in motor control and sensor acquisition.
What low-power modes are supported by the MKE17Z128VLF7?
The MKE17Z128VLF7 implements six low-power modes managed by the Power Management Controller (PMC): Run (RUN), Very Low Power Run (VLPR), Wait (Wait), Very Low Power Wait (VLPW), Stop (Stop), and Very Low Power Stop (VLPS). In VLPS mode, the MCU draws ~3.2 μA while retaining SRAM, enabling wake-up via ADC, CMP, LPUART, TSI, or LPIT - critical for battery-operated endpoints.
Is the MKE17Z128VLF7 pin-compatible with other Kinetis KE1xZ variants?
Yes, the MKE17Z128VLF7 shares identical 48-pin LQFP (LF) mechanical and electrical pinout with all other KE1xZ family members in the same package variant - including MKE17Z256VLF7, MKE13Z128VLF7, and MKE12Z128VLF7. This allows direct substitution within the same footprint for flash/RAM scaling or performance tiering without PCB redesign.
