NXP Semiconductors MKE14Z64VLD4

Overview

MKE14Z64VLD4 from NXP is a 48 MHz Arm Cortex-M0+ microcontroller with 64 KB flash, 8 KB SRAM, integrated capacitive touch sensing (25 channels), MSCAN interface, and 1 Msps 12-bit ADC-designed for motor control and industrial HMI in electrically harsh 5 V environments.

For engineers reviewing the MKE14Z64VLD4 datasheet, MKE14Z64VLD4 pinout, MKE14Z64VLD4 application, or MKE14Z64VLD4 equivalent, key selection criteria include 2.7–5.5 V operation, −40 to 105 °C temperature range, LQFP-48 package compatibility, CAN bus support, and TSI-based touch robustness in wet or noisy conditions.

Technical Context

The MKE14Z64VLD4 implements an Arm Cortex-M0+ core with Thumb-2 instruction set and single-cycle I/O access, paired with a dedicated Touch Sense Interface (TSI) supporting both self- and mutual-capacitance modes. Its MSCAN module complies with ISO 11898-1:2015 and supports standard/extended frames at up to 1 Mbps.

Analog subsystem includes a 12-bit SAR ADC with hardware trigger via PDB and configurable sample rates up to 1 MSPS, plus four analog comparators (ACMP) with programmable hysteresis and internal reference. System clocking supports internal 48 MHz FRO and external crystal options with fractional PLL.

FAQ

Does the MKE14Z64VLD4 include a capacitive touch interface?

No, the MKE14Z64VLD4 does not integrate the Touch Sense Interface (TSI). Unlike the MKE15Z and MKE16Z variants, this part omits TSI while retaining MSCAN, making it suitable for CAN-centric applications without touch requirements. The MKE14Z64VLD4 datasheet confirms absence of TSI registers and related pin functions.

What is the maximum operating frequency of the MKE14Z64VLD4 core?

The MKE14Z64VLD4 features an Arm Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achieved using the internal 48 MHz FRO (Fast Reference Oscillator) or via PLL multiplication of lower-frequency sources. All timing-critical peripherals-including FTM, ADC, and MSCAN-are fully functional at this speed.

Which development boards support the MKE14Z64VLD4?

No official NXP development board uses the exact MKE14Z64VLD4 variant. However, the FRDM-KE16Z board (based on MKE16Z64VLF4) shares identical pinout, memory map, and peripheral configuration-enabling direct firmware reuse and hardware evaluation with minor software adaptation for missing TSI features.

Is the MKE14Z64VLD4 pin-compatible with other KE1xZ devices in LQFP-48 package?

Yes, the MKE14Z64VLD4 is pin-compatible with MKE15Z64VLD4 and MKE16Z64VLD4 in the 48LQFP package. Signal mapping for GPIO, CAN, ADC, and timers is identical; differences are limited to unused TSI pins on MKE14Z64VLD4, which remain NC or configurable as GPIO.

What industrial certifications does the MKE14Z64VLD4 meet?

The MKE14Z64VLD4 is qualified to AEC-Q100 Grade 2 (−40 to 105 °C) and meets IEC 61000-4-2 (ESD ±8 kV contact), IEC 61000-4-4 (EFT ±2 kV), and IEC 61000-4-6 (CS 10 Vrms) standards. These ratings are documented in NXP's Kinetis E family EMC test reports, confirming suitability for industrial control and appliance applications.
