Product details
Overview
MKE13Z256VLF7 from NXP Semiconductors is a 48-pin LQFP ARM® Cortex®-M0+ microcontroller operating up to 72 MHz, featuring 256 KB flash, 48 KB SRAM, and integrated 12-bit ADC (11 channels), dual TSI modules (15 touch channels), and three LPUART interfaces - deployed in industrial motor control and HMI-sensing applications.
For engineers reviewing the MKE13Z256VLF7 datasheet, MKE13Z256VLF7 pinout, MKE13Z256VLF7 application, or MKE13Z256VLF7 equivalent, key selection criteria include its 48 LQFP package with 42 GPIOs (6 high-drive), VLPS-mode operation down to 2.7 V, and support for BLDC commutation via FTM PWM with deadtime insertion.
Technical Context
The MKE13Z256VLF7 implements an ARMv6-M architecture with Thumb-2 ISA, paired with a configurable NVIC supporting 32 interrupt vectors and 4 priority levels. Its clock system integrates SCG with multiple sources - FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), LPO (128 kHz), and LPFLL - enabling dynamic mode switching across RUN, VLPR, WAIT, VLPW, STOP, and VLPS.
Peripheral subsystems are tightly coupled via a crossbar switch: eDMA (8 channels, extended to 63 via DMAMUX) routes triggers from FTM, LPIT, LPTMR, and CMP to ADC and communication peripherals; dual TSI modules provide mutual-capacitance sensing with shield channel support for noise-immune HMI; and the 12-bit ADC operates at up to 1 Msps with self-calibration and hardware averaging.

FAQ
What is the maximum operating frequency of the MKE13Z256VLF7?
The MKE13Z256VLF7 features an ARM Cortex-M0+ core rated for up to 72 MHz operation. This frequency is achievable using the 48 MHz Fast Internal Reference Clock (FIRC) with PLL multiplication or directly from an external crystal oscillator. 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 MKE13Z256VLF7 support hardware debugging?
Yes, the MKE13Z256VLF7 includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It supports full run-control debugging, breakpoint setting, memory inspection, and real-time trace via the Micro Trace Buffer (MTB). SWD uses only two pins (SWDIO and SWCLK), minimizing PCB footprint, and remains functional across all power modes except deep reset states - enabling in-system validation of motor control algorithms and touch firmware.
How many analog-to-digital converter channels does the MKE13Z256VLF7 have?
The MKE13Z256VLF7 integrates one 12-bit successive approximation register (SAR) ADC module with 11 single-ended external input channels. These channels are mapped to specific GPIO pins and support hardware triggering from FTM, LPTMR, or comparator outputs. The ADC also includes an internal temperature sensor channel (AD26) and supports self-calibration to maintain accuracy across voltage and temperature variations - critical for thermal monitoring in motor control applications.
Can the MKE13Z256VLF7 operate in ultra-low-power modes with peripherals active?
Yes, the MKE13Z256VLF7 supports Very Low Power Stop (VLPS) mode with selected peripherals remaining operational - including the 12-bit ADC, analog comparators (CMP), LPUART, LPIT, and FlexIO - while drawing less than 2 μA typical current. This capability enables wake-on-event functionality (e.g., UART frame reception or ADC threshold crossing) without sacrificing system responsiveness, making it ideal for battery-powered sensor nodes and always-on HMI interfaces.
What touch sensing capability does the MKE13Z256VLF7 provide?
The MKE13Z256VLF7 integrates two Touch Sensing Interface (TSI) modules supporting a total of 15 touch channels - configured as mutual-capacitance inputs with optional shield channels for noise immunity. Each TSI module includes digital filtering, automatic baseline tracking, and hardware-accelerated signal processing, enabling robust capacitive button, slider, and proximity detection in industrial environments with high EMI. No external components are required for basic operation.
