NXP Semiconductors MKE15Z64VLF4

Overview

MKE15Z64VLF4 from NXP is a 48 MHz Arm® Cortex®-M0+ microcontroller with 64 KB flash, 8 KB SRAM, integrated Touch Sense Interface (TSI) supporting 25 channels, 1 Msps 12-bit ADC, and MSCAN controller - deployed in industrial HMI control, BLDC motor drive interfaces, and harsh-environment appliance main boards.

For engineers reviewing the MKE15Z64VLF4 datasheet, MKE15Z64VLF4 pinout, MKE15Z64VLF4 application, or MKE15Z64VLF4 equivalent, key selection criteria include 2.7–5.5 V operation, 5 V I/O tolerance, CAN 2.0B compliance, TSI liquid-tolerance capability, and LQFP-48 package compatibility with FRDM-KE16Z development hardware.

Technical Context

The MKE15Z64VLF4 implements an Arm Cortex-M0+ core with Thumb-2 instruction set and single-cycle I/O access, paired with a dedicated TSI module supporting self-capacitive and mutual-capacitive sensing modes. Its MSCAN peripheral conforms to ISO 11898-1:2015 with programmable bit timing and loopback test mode.

It integrates a 12-bit SAR ADC with hardware trigger synchronization via PDB, six-channel FTM for complementary PWM generation in BLDC control, and LPIT/LPTMR timers enabling low-power periodic wake-up at sub-millisecond resolution under 2.7 V supply.

FAQ

What is the maximum operating frequency of the MKE15Z64VLF4?

The MKE15Z64VLF4 operates at a maximum core 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, 2.7–5.5 V). All peripherals-including the 1 Msps ADC, TSI, and MSCAN-are functional at this clock rate, and the device includes internal PLL and FLL circuitry to maintain timing accuracy under varying supply conditions. The MKE15Z64VLF4 achieves deterministic real-time performance critical for motor control and touch response timing.

Does the MKE15Z64VLF4 include a CAN controller?

No, the MKE15Z64VLF4 does not integrate a CAN controller. While it shares the same core, memory, TSI, and package with the MKE16Z64VLF4, CAN functionality is exclusive to the KE16Z variant. The MKE15Z64VLF4 provides LPUART, LPSPI, and LPI2C for serial communication but lacks MSCAN hardware. Engineers requiring CAN must select MKE16Z64VLF4 or implement external CAN transceivers with protocol handling in software - though the latter increases latency and CPU load. The MKE15Z64VLF4 datasheet explicitly omits CAN from its peripheral list.

How many touch sensing channels does the MKE15Z64VLF4 support?

The MKE15Z64VLF4 supports up to 25 independent touch sensing channels via its integrated Touch Sense Interface (TSI) module. These channels can be configured in either self-capacitive mode (25 electrodes) or mutual-capacitive mode (12 electrode pairs), with programmable charge current and scan resolution. The TSI hardware includes built-in noise filtering and auto-calibration routines, enabling reliable operation in presence of moisture or EMI. This capability allows the MKE15Z64VLF4 to replace multiple discrete touch controllers in HMI applications such as appliance control panels and elevator call buttons.

What development tools are compatible with the MKE15Z64VLF4?

The MKE15Z64VLF4 is supported by NXP's MCUXpresso SDK, MCUXpresso Config Tools, and MCUXpresso IDE, all freely available and actively maintained. It is also compatible with IAR Embedded Workbench and Arm Keil MDK. Although no dedicated FRDM board uses the exact MKE15Z64VLF4, the FRDM-KE16Z board (featuring MKE16Z64VLF4) is pin-compatible and software-compatible - allowing full evaluation of TSI, ADC, and communication peripherals. The MKE15Z64VLF4 shares the same register map and toolchain support as other KE1xZ devices, enabling seamless migration from KE14Z or KE16Z projects.

Is the MKE15Z64VLF4 qualified for automotive applications?

The MKE15Z64VLF4 is not AEC-Q100 qualified and is not marketed for automotive use. It is rated for industrial temperature range (−40 °C to +105 °C) and designed for home appliance, industrial control, and general-purpose 5 V robust applications. While its EMC/ESD robustness meets IEC 61000-4-x standards relevant to factory environments, it lacks automotive-specific qualifications such as PPAP documentation, zero-defect manufacturing traceability, or extended lifetime validation. For automotive body electronics or infotainment interfaces, NXP recommends AEC-Q100 qualified variants like S32K116 or K32L2B3. The MKE15Z64VLF4 remains appropriate for non-safety-critical industrial equipment where automotive-grade certification is not mandated.
