Product details
Overview
MKE14Z64VLF4R from NXP Semiconductors is a 48 MHz Arm® Cortex®-M0+ microcontroller with 64 KB flash, 8 KB SRAM, 42 GPIOs, 12-bit ADC (1 Msps), and no CAN or TSI modules - optimized for cost-sensitive industrial control and appliance subsystems requiring deterministic real-time response and low-power operation across –40 to 105 °C.
For engineers reviewing the MKE14Z64VLF4R datasheet, MKE14Z64VLF4R pinout, MKE14Z64VLF4R application, or MKE14Z64VLF4R equivalent, key selection criteria include its LQFP-48 package, absence of CAN/TSI peripherals, support for VLPS/Stop mode wake-up via LPUART/LPTMR/RTC/CMP, and compatibility with NXP's KE1xZ software ecosystem including MCUXpresso SDK and Kinetis Design Studio.
Technical Context
The MKE14Z64VLF4R implements an Armv6-M architecture core with Thumb-2 ISA, nested vectored interrupt controller (NVIC) supporting 32 IRQ sources, and memory-mapped divide/square-root (MMDVSQ) module. It uses the System Clock Generator (SCG) to route FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), LPO (128 kHz), and external crystal (4–40 MHz) to bus, core, and peripheral domains.
Power management is handled by the PMC with six operational modes: RUN, VLPR, WAIT, VLPW, STOP, and VLPS - enabling sub-μA retention in VLPS while maintaining RTC, LPTMR, CMP, LPUART, and ADC functionality. Wake-up from VLPS is supported via AWIC using LPUART, LPI2C, LPSPI, LPIT, LPTMR, RTC, or pin interrupts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKE15Z64VLF4 | Includes MSCAN module; identical flash/RAM/timing/peripherals otherwise. | Required where CAN bus integration is needed for industrial fieldbus communication. | Select MKE15Z64VLF4 only if CAN physical layer and protocol stack support are mandatory - adds no cost penalty but increases software complexity. |
| MKE14Z64VLD4 | Same core/peripherals but in 44-pin LQFP (10 × 10 mm, 0.8 mm pitch); 38 GPIOs, 36 ADC channels. | Suitable for space-constrained PCBs where reduced I/O count is acceptable. | Choose MKE14Z64VLD4 when board area is limited and fewer GPIOs/ADC channels suffice - same firmware compatibility with pin mapping adjustment. |
Compared with MKE14Z64VLF4R, MKE15Z64VLF4 adds CAN capability without altering power or timing behavior, while MKE14Z64VLD4 trades package size and I/O count for identical functionality - making both viable alternatives depending on interface and layout constraints.

FAQ
What is the maximum operating frequency of the MKE14Z64VLF4R?
The MKE14Z64VLF4R operates at a maximum core frequency of 48 MHz using the Fast Internal Reference Clock (FIRC), which is factory-trimmed to ±1% accuracy. This frequency is achievable in RUN and VLPR modes, with bus clock derived at half-core speed (24 MHz) for peripheral operation - ensuring deterministic timing for real-time control loops without external crystal dependency.
Does the MKE14Z64VLF4R support CAN communication?
No, the MKE14Z64VLF4R does not include a CAN module. Per NXP's official ordering table, this variant explicitly omits MSCAN functionality - unlike MKE15Z64VLF4 or MKE16Z64VLF4. Designers requiring CAN must select one of those variants or add an external CAN transceiver with SPI interface, though that increases BOM cost and PCB area.
What low-power modes are supported by the MKE14Z64VLF4R?
The MKE14Z64VLF4R supports six power modes: RUN, VLPR, WAIT, VLPW, STOP, and VLPS. In VLPS mode, it draws less than 2 μA while retaining RTC, LPTMR, CMP, LPUART, and ADC functionality - enabling event-driven wake-up without external wake sources. All modes are controlled via the Power Management Controller (PMC) and invoked using WFI/WFE instructions.
How many GPIO pins does the MKE14Z64VLF4R provide?
The MKE14Z64VLF4R provides 42 GPIO pins across PORTA through PORTE, with 6 designated as high-drive outputs capable of sourcing/sinking up to 20 mA. Pin multiplexing is managed via the Port Control Module (PORT), allowing each pin to be configured for GPIO, UART, SPI, I²C, ADC, or timer functions - all accessible in the 48-LQFP package used by MKE14Z64VLF4R.
Is the MKE14Z64VLF4R pin-compatible with other KE1xZ devices?
Yes, the MKE14Z64VLF4R shares the same 48-LQFP package and pinout as MKE15Z64VLF4 and MKE16Z64VLF4 - differing only in peripheral enablement (CAN/TSI). Firmware developed for MKE14Z64VLF4R will run unchanged on those variants, and hardware layouts can be reused with minor configuration changes in the SIM_SOPT register to enable or disable specific modules.
