NXP Semiconductors MKE15Z64VFP4R

Overview

MKE15Z64VFP4R from NXP Semiconductors is a 40-pin QFN-packaged Arm® Cortex®-M0+ microcontroller operating up to 48 MHz, featuring 64 KB flash, 8 KB SRAM, 12-bit ADC with 11 analog inputs, TSI touch interface, and no CAN module-targeting cost-sensitive industrial control and home appliance UIs requiring low-power operation and robust capacitive sensing.

For engineers reviewing the MKE15Z64VFP4R datasheet, MKE15Z64VFP4R pinout, MKE15Z64VFP4R application, or MKE15Z64VFP4R equivalent, key selection criteria include its 40-QFN footprint, absence of CAN (vs. MKE16Z variants), TSI support for up to 25 channels, LPUART×3/LPSPI×1/LPI2C×1 peripheral set, and VLPS/Stop-mode wake-up capability via CMP, RTC, LPTMR, and GPIO.

Technical Context

The MKE15Z64VFP4R implements an Armv6-M Thumb-2 ISA core with NVIC supporting 32 interrupt vectors and 4 priority levels, paired with MMDVSQ for hardware divide/sqrt acceleration. Its SCG clock system integrates FIRC (±1%), SIRC (±3%), LPO, LPFLL, and external crystal support (4–40 MHz / 32–40 kHz), enabling precise low-power timing across Run, Wait, Stop, VLPR, VLPW, and VLPS modes.

Peripheral integration centers on deterministic real-time control: two FlexTimers (6+2 PWM channels), LPIT (2-channel periodic interrupt), PDB for ADC trigger synchronization, LPTMR for wake-up-capable timing, and a self-calibrating 12-bit ADC with hardware averaging and temperature sensor-each functional in VLPS mode when clocked from SIRC or OSC.

FAQ

What is the maximum operating frequency of the MKE15Z64VFP4R?

The MKE15Z64VFP4R operates at a maximum core frequency of 48 MHz using the 48 MHz Fast Internal Reference Clock (FIRC) with ±1% accuracy, or up to 50 MHz with external square-wave clock input. This frequency is fully supported across all active power modes including Run and VLPR, enabling real-time control loop execution within tight timing budgets.

Does the MKE15Z64VFP4R include a CAN interface?

No, the MKE15Z64VFP4R does not include a CAN module. Unlike the MKE16Z64 variants, this part belongs to the MKE15Z sub-family which omits the MSCAN peripheral. Its communication interfaces are limited to LPUART×3, LPSPI×1, and LPI2C×1-sufficient for local sensor networks and appliance control but not for industrial fieldbus applications requiring CAN.

What package type and dimensions does the MKE15Z64VFP4R use?

The MKE15Z64VFP4R uses a 40-pin QFN package (5×5×0.85 mm body, 0.4 mm pitch), with exposed thermal pad on the underside. It complies with JEDEC MO-220 packaging standards and has moisture sensitivity level 3, requiring bake-before-reflow handling per J-STD-020.

How many analog-to-digital converter (ADC) channels does the MKE15Z64VFP4R support?

The MKE15Z64VFP4R integrates one 12-bit SAR ADC supporting up to 11 single-ended external analog inputs, plus an internal temperature sensor channel (AD26). It features hardware averaging, programmable sample time, and self-calibration-enabling accurate sensor readings across its full –40 to +105 °C operating range.

Can the MKE15Z64VFP4R operate in ultra-low-power modes with peripherals active?

Yes, the MKE15Z64VFP4R supports Very Low Power Stop (VLPS) mode with selected peripherals active-including RTC, LPTMR, CMP, ADC (when clocked from SIRC or OSC), LPUART, LPI2C, and LPSPI. In VLPS, current consumption drops below 10 µA while retaining wake-up capability via GPIO, comparator output, or timer expiration.
