Product details
Overview
MKE15Z32VLD4 from NXP is a 32 KB Flash, 4 KB SRAM Arm Cortex-M0+ microcontroller operating at 48 MHz with integrated Touch Sense Interface (TSI), MSCAN controller, 12-bit 1 MSPS ADC, and 25-channel capacitive touch support - deployed in industrial HMI control panels and motor drive UIs requiring 5V robustness and EMC resilience.
For engineers reviewing the MKE15Z32VLD4 datasheet, MKE15Z32VLD4 pinout, MKE15Z32VLD4 application, or MKE15Z32VLD4 equivalent, key selection criteria include 2.7–5.5 V supply range, -40°C to 105°C operation, LQFP-48 package compatibility, CAN bus integration, and TSI liquid-tolerant self/mutual-capacitance sensing capability.
Technical Context
The MKE15Z32VLD4 implements an Arm Cortex-M0+ core with Thumb-2 instruction set and NVIC-based interrupt handling, paired with a dedicated Touch Sense Interface supporting both self-capacitance and mutual-capacitance modes across 25 pins. Its MSCAN module complies with ISO 11898-1 (CAN 2.0B) and supports programmable bit rates up to 1 Mbps.
System-level features include a 12-bit SAR ADC with 1 MSPS sampling rate, six-channel FlexTimer Module (FTM) for PWM generation and quadrature decoding, and low-power peripherals (LPUART, LPSPI, LPI2C) enabling battery-backed operation in harsh environments.

FAQ
What is the maximum operating frequency of the MKE15Z32VLD4?
The MKE15Z32VLD4 operates at a maximum core clock frequency of 48 MHz using its Arm Cortex-M0+ processor. This speed is fully supported across the entire specified temperature and voltage range (−40°C to +105°C, 2.7 V to 5.5 V). The MKE15Z32VLD4 achieves this performance with optimized flash wait-state configuration and internal clock dividers that maintain timing integrity for all peripherals including ADC, FTM, and MSCAN.
Does the MKE15Z32VLD4 support both self-capacitance and mutual-capacitance touch sensing?
Yes, the MKE15Z32VLD4 integrates a dedicated Touch Sense Interface (TSI) that natively supports both self-capacitance and mutual-capacitance measurement modes. It provides 25 configurable touch channels with hardware-accelerated charge-transfer measurement, automatic baseline tracking, and built-in compensation for environmental drift - enabling reliable operation in humid or wet conditions typical of kitchen appliances and industrial enclosures.
Is the MKE15Z32VLD4 pin-compatible with other KE1xZ family members in the same LQFP-48 package?
Yes, the MKE15Z32VLD4 shares identical pinout and electrical characteristics with other KE1xZ devices in the 48LQFP package, including MKE14Z32VLD4 and MKE16Z32VLD4. This allows hardware reuse across variants - for example, a single PCB can support touch-only (MKE15Z), non-touch (MKE14Z), or CAN-enabled (MKE16Z) configurations by changing only the firmware and optional transceiver components.
What development tools are officially supported for the MKE15Z32VLD4?
The MKE15Z32VLD4 is fully supported by NXP's MCUXpresso SDK, MCUXpresso Config Tools, and MCUXpresso IDE. It also works with IAR Embedded Workbench and Arm Keil MDK. Hardware evaluation is enabled via the FRDM-KE15Z and FRDM-KE16Z Freedom boards - both of which provide onboard debug, CAN transceivers, and capacitive touch electrodes compatible with the MKE15Z32VLD4's TSI peripheral.
What is the temperature grade and industrial qualification status of the MKE15Z32VLD4?
The MKE15Z32VLD4 is rated for industrial temperature operation from −40°C to +105°C and is qualified per AEC-Q100 Grade 2 standards for reliability in harsh environments. Its design includes enhanced ESD protection (±8 kV HBM), EMC-hardened I/O structures, and 5V-tolerant pins - making it suitable for deployment in factory automation, HVAC, and home appliance applications where electrical noise and thermal stress are common.
