Product details
Overview
MKE13Z128VLF7 from NXP Semiconductors is an ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 128 KB flash, 32 KB SRAM, and a 12-bit 1 Msps ADC. It integrates three LPUARTs, one LPSPI, one LPI2C, two TSI modules (15-channel touch sensing), and supports VLPS/Stop low-power modes with AWIC wake-up - used in BLDC motor control and industrial HMI systems.
For engineers reviewing the MKE13Z128VLF7 datasheet, MKE13Z128VLF7 pinout, MKE13Z128VLF7 application, or MKE13Z128VLF7 equivalent, key selection criteria include its 48-pin LQFP package, 2.7–5.5 V operation, –40 to 105 °C temperature range, and integrated analog peripherals for cost-sensitive embedded control.
Technical Context
The MKE13Z128VLF7 implements a single-core ARM Cortex-M0+ executing Thumb-2 instructions at up to 72 MHz, with NVIC supporting 32 interrupt vectors and 4 priority levels. 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).
Power management uses PMC to manage Run, Wait, Stop, VLPR, VLPW, and VLPS modes; AWIC enables asynchronous wake-up from Stop/VLPS using CMP, ADC, LPUART, LPSPI, LPI2C, LPIT, FlexIO, or LPTMR. 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 clock sources.

FAQ
What is the maximum operating frequency of the MKE13Z128VLF7?
The MKE13Z128VLF7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This maximum frequency is achievable when powered within the 2.7–5.5 V supply range and operating across the full –40 to 105 °C ambient temperature range. The system clock is derived from the SCG using FIRC (48 MHz ±1%), LPFLL, or external crystal sources - with frequency multiplication and gating managed entirely in hardware.
Does the MKE13Z128VLF7 support debugging via Serial Wire Debug?
Yes, the MKE13Z128VLF7 includes a standard ARM Serial Wire Debug (SWD) interface using SWD_DIO and SWD_CLK pins. This two-wire interface supports full run-control debugging, real-time register inspection, flash programming, and Micro Trace Buffer (MTB) trace capture - all without consuming any GPIO resources or requiring additional external circuitry.
How many touch sensing channels does the MKE13Z128VLF7 support?
The MKE13Z128VLF7 integrates two TSI modules supporting a total of 15 mutual-capacitance touch channels. This count is confirmed in Table 1 of the KE1xZ data sheet for the VLF7 package variant. Each TSI module also includes shield channels for noise immunity, and both operate fully in VLPS mode to enable ultra-low-power touch wake-up functionality.
Can the MKE13Z128VLF7 operate in very low power stop (VLPS) mode with peripherals active?
Yes, the MKE13Z128VLF7 supports VLPS mode with selected peripherals active, including the 12-bit ADC, analog comparator (CMP), LPUART, LPSPI, LPI2C, LPIT, FlexIO, and DMA - all clocked from SIRC or OSC sources. Wake-up is handled by the Asynchronous Wake-up Interrupt Controller (AWIC), allowing immediate resumption from sub-10 µA sleep current without full system restart.
What is the ADC resolution and sampling rate of the MKE13Z128VLF7?
The MKE13Z128VLF7 includes a single 12-bit successive approximation register (SAR) ADC capable of up to 1 Msps (mega-samples per second). It supports 11 external analog input channels in the VLF7 package, with hardware averaging, self-calibration, and flexible trigger sources including FTM, LPTMR, and external pins - ensuring precision measurement in motor control and sensor applications.
