Product details
Overview
MKE14Z64VLF4 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, industrial HMI, and appliance UI in electrically harsh 5 V environments.
For engineers reviewing the MKE14Z64VLF4 datasheet, MKE14Z64VLF4 pinout, MKE14Z64VLF4 application, or MKE14Z64VLF4 equivalent, key selection criteria include 2.7–5.5 V operation, CAN bus support, TSI liquid-tolerant touch capability, and LQFP-48 packaging with industrial temperature range (−40°C to +105°C).
Technical Context
The MKE14Z64VLF4 implements an Arm Cortex-M0+ core with tightly coupled NVIC and SysTick, operating at up to 48 MHz with 1.25 DMIPS/MHz efficiency. It integrates a dedicated Touch Sense Interface (TSI) supporting both self-capacitive and mutual-capacitive modes, enabling robust HMI in wet or noisy conditions.
Its analog subsystem includes a 12-bit, 1 Msps ADC with hardware averaging and programmable gain, two FlexTimer Modules (FTM) for PWM generation and quadrature decoding, and a 4-channel analog comparator (ACMP) with window mode-optimized for BLDC motor commutation and real-time fault detection.

FAQ
What is the maximum operating frequency of the MKE14Z64VLF4?
The MKE14Z64VLF4 operates at a maximum core clock frequency of 48 MHz, derived from its Arm Cortex-M0+ processor. This frequency is fully supported across the entire industrial temperature range (−40°C to +105°C) and 2.7–5.5 V supply voltage. The MKE14Z64VLF4 achieves consistent timing behavior for real-time motor control loops and touch scanning without derating.
Does the MKE14Z64VLF4 support CAN FD or only classical CAN?
The MKE14Z64VLF4 integrates the MSCAN module, which supports Classical CAN (ISO 11898-1) up to 1 Mbps but does not support CAN FD features such as flexible data-rate or extended frame formats. For CAN FD capability, designers should consider the MKE16Z64VLF4, which replaces MSCAN with a CAN FD controller while maintaining pin compatibility and memory configuration.
How many touch sensing channels does the MKE14Z64VLF4 provide?
The MKE14Z64VLF4 provides 25 dedicated touch sensing channels via its integrated Touch Sense Interface (TSI). These channels support both self-capacitive and mutual-capacitive configurations, with hardware-accelerated scanning and automatic calibration-enabling robust implementation of sliders, wheels, and multi-button interfaces on a single MKE14Z64VLF4 device.
Is the MKE14Z64VLF4 pin-compatible with other KE1xZ family members?
The MKE14Z64VLF4 uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) that matches the footprint of MKE15Z64VLF4 and MKE16Z64VLF4. While pin functions are largely aligned across these variants, CAN-related signals (e.g., CAN_TX/CAN_RX) are only present on MKE14Z64VLF4 and MKE16Z64VLF4-not on MKE15Z64VLF4-so PCB layout reuse requires verification of peripheral signal mapping.
What development tools are supported for the MKE14Z64VLF4?
The MKE14Z64VLF4 is supported by NXP's MCUXpresso SDK, MCUXpresso IDE, and configuration tools. It is also compatible with IAR Embedded Workbench and Arm Keil MDK. Although no dedicated FRDM board targets MKE14Z64VLF4, the FRDM-KE16Z board (featuring MKE16Z64VLF4) can be used for software development and debugging due to architectural and peripheral similarity-requiring minor pin mapping adjustments for CAN and touch resources.
