NXP Semiconductors MKE14Z64VFP4

Overview

MKE14Z64VFP4 from NXP Semiconductors is a 40-pin QFN-packaged Arm® Cortex®-M0+ microcontroller operating at up to 48 MHz, featuring 64 KB flash, 8 KB SRAM, one 12-bit ADC (11-channel), no TSI module, and no CAN interface-targeting cost-sensitive industrial control and sensor node applications requiring robust low-power operation across –40 to 105 °C.

For engineers reviewing the MKE14Z64VFP4 datasheet, MKE14Z64VFP4 pinout, MKE14Z64VFP4 application, or MKE14Z64VFP4 equivalent, key selection criteria include its 40-QFN footprint, absence of touch sense and CAN peripherals, support for LPUART/LPSPI/LPI2C in VLPS mode, and verified operation under 2.7–5.5 V with integrated WDOG/EWM and CRC.

Technical Context

The MKE14Z64VFP4 implements an Arm Cortex-M0+ core compliant with ARMv6-M and Thumb-2 ISA, paired with a configurable NVIC supporting 32 interrupt vectors and 4 priority levels. Its power architecture includes PMC-managed Run, Wait, Stop, VLPR, VLPW, and VLPS modes, with AWIC enabling wake-up from VLPS/Stop via LPUART, LPSPI, LPI2C, CMP, RTC, or GPIO.

Peripherals are clocked via SCG with FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), LPO (128 kHz), and LPFLL; all analog/digital modules-including 12-bit ADC (1 Msps), dual FlexTimer (6+2 PWM channels), LPIT (2-channel), PDB, and LPTMR-retain functionality in VLPS when sourced from SIRC or OSC, enabling deterministic low-power timing and sensing.

FAQ

What is the maximum operating frequency of the MKE14Z64VFP4?

The MKE14Z64VFP4 operates at up to 48 MHz using the Fast Internal Reference Clock (FIRC), which is factory-trimmed to ±1% accuracy. This frequency is supported across all operating voltage ranges (2.7–5.5 V) and ambient temperatures (–40 to 105 °C), enabling deterministic real-time execution without external crystal dependency. The MKE14Z64VFP4 also supports lower-frequency modes via SIRC (8/2 MHz) and LPO (128 kHz) for ultra-low-power operation.

Does the MKE14Z64VFP4 support CAN communication?

No, the MKE14Z64VFP4 does not include a CAN controller. According to NXP's official ordering information table, only MKE15Z and MKE16Z variants (e.g., MKE15Z64VFP4) integrate the MSCAN module. The MKE14Z64VFP4 is explicitly designated as "No" for CAN in the product matrix, making it suitable for applications where CAN is unnecessary-reducing cost, firmware overhead, and qualification scope.

What low-power modes are available on the MKE14Z64VFP4, and which peripherals remain active in VLPS?

The MKE14Z64VFP4 supports six power modes: Run, VLPR, Wait, VLPW, Stop, and VLPS. In VLPS mode, the ADC, CMP, OSC, RTC, LPTMR, LPIT, LPUART, LPI2C, LPSPI, and DMA remain operational when clocked from SIRC or OSC. The NVIC is disabled, but AWIC handles wake-up events. This enables sub-μA retention with responsive peripheral-triggered wake-up-critical for battery-powered MKE14Z64VFP4 deployments.

How many ADC channels does the MKE14Z64VFP4 support, and what is its resolution?

The MKE14Z64VFP4 integrates one 12-bit successive approximation register (SAR) ADC with up to 11 external analog input channels (ADC0_SE0–SE10), as confirmed in the ordering information table and electrical characteristics section. It supports 12-bit, 10-bit, and 8-bit output modes, programmable sample time, hardware triggering from timers or comparators, and self-calibration-delivering high-precision sensor acquisition without external signal conditioning for the MKE14Z64VFP4.

Is the MKE14Z64VFP4 pin-compatible with other KE1xZ variants in the 40-QFN package?

Yes, the MKE14Z64VFP4 shares identical 40-QFN pinout and footprint with MKE15Z64VFP4, MKE14Z32VFP4, and MKE15Z32VFP4, as verified in NXP's package drawing 98ASA01371D and signal multiplexing tables. All share the same VDD/VSS, GPIO, ADC, UART, SPI, I²C, reset, and SWD pin assignments-enabling hardware reuse across flash/RAM variants and simplifying migration between MKE14Z64VFP4 and MKE14Z32VFP4.
