Product details
Overview
MKE14Z32VFP4 from NXP Semiconductors is a 32 KB flash, 4 KB SRAM Arm® Cortex®-M0+ microcontroller in 40-pin QFN (5×5 mm, 0.4 mm pitch), operating up to 48 MHz with 12-bit ADC (1 Msps), CAN interface, and LPUART/LPSPI/LPI2C peripherals - designed for industrial control and appliance touch UI where low-power operation and robust communication are required.
For engineers reviewing the MKE14Z32VFP4 datasheet, MKE14Z32VFP4 pinout, MKE14Z32VFP4 application, or MKE14Z32VFP4 equivalent, key selection criteria include its 40-QFN package footprint, absence of TSI and CAN (vs. MKE16Z variants), support for VLPS/Stop modes with RTC/LPTMR wakeup, and compatibility with KE1xZ software ecosystem and MCUXpresso IDE.
Technical Context
The MKE14Z32VFP4 implements an Arm Cortex-M0+ core at up to 48 MHz with Thumb-2 ISA, NVIC supporting 32 interrupt vectors and 4 priority levels, and memory-mapped divide/square root (MMDVSQ) acceleration. It integrates SCG clock generation with FIRC (±1%), SIRC (±3%), and LPO sources, enabling precise low-power timing across Run, Wait, Stop, VLPR, VLPW, and VLPS modes.
Peripheral subsystems include one 12-bit SAR ADC (12-channel, 1 Msps), one analog comparator with integrated 8-bit DAC, two FlexTimers (6+2 PWM channels), LPIT (2-channel), LPTMR, PDB, RTC, CRC, WDOG/EWM watchdogs, and three LPUARTs - all accessible in low-power states via AWIC-triggered wake-up from VLPS/Stop using GPIO, LPUART, RTC, or LPTMR.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
Does MKE14Z32VFP4 include a touch sense interface (TSI)?
No, MKE14Z32VFP4 does not include the TSI module. Per NXP's official ordering table, only MKE15Z and MKE16Z variants (e.g., MKE15Z32VFP4) feature TSI support. The MKE14Z32VFP4 is optimized for non-touch applications requiring CAN, ADC, and low-power UART/SPI/I2C interfaces.
What is the maximum operating frequency of MKE14Z32VFP4?
The MKE14Z32VFP4 supports a maximum core clock frequency of 48 MHz, achievable using the 48 MHz Fast Internal Reference Clock (FIRC) with ±1% accuracy or an external crystal oscillator. This frequency is maintained across all supported voltage ranges (2.7–5.5 V) and temperature grades (–40 to +105 °C).
Can MKE14Z32VFP4 operate in very low power stop (VLPS) mode with CAN active?
No, the CAN module is not operational in VLPS mode on MKE14Z32VFP4. According to the reference manual, MSCAN requires the system clock and cannot wake from VLPS; it remains disabled during VLPS. For CAN-based wake-up, use Stop mode instead, where CAN is functional and can generate interrupts via AWIC.
Which debug interface does MKE14Z32VFP4 support?
MKE14Z32VFP4 supports Serial Wire Debug (SWD) via dedicated SWD_CLK and SWD_DIO pins. It does not support JTAG. SWD enables full programming, real-time debugging, and trace capabilities using standard ARM-compliant tools such as LPC-Link2, SEGGER J-Link, or NXP's own LPC-Link2-based MCUXpresso IDE.
Is MKE14Z32VFP4 pin-compatible with other KE1xZ variants in 40-QFN?
Yes, MKE14Z32VFP4 shares identical 40-QFN pinout and footprint with MKE14Z64VFP4, MKE15Z32VFP4, and MKE15Z64VFP4. All four parts use the same 5×5 mm, 0.4 mm pitch package with identical signal assignments - enabling hardware reuse across flash/RAM/feature variants without PCB redesign.
