Product details
Overview
MKL14Z64VFT4R from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ based microcontroller in the Kinetis KL14 sub-family, designed for ultra-low-power embedded applications. It integrates 64 KB flash, 8 KB SRAM, a 12-bit SAR ADC, two UARTs, two I²C modules, two SPI interfaces, six-channel TPM, and operates across –40°C to 105°C at 1.71–3.6 V supply - ideal for battery-powered sensor nodes and industrial control edge devices.
For engineers reviewing the MKL14Z64VFT4R datasheet, MKL14Z64VFT4R pinout, MKL14Z64VFT4R application, or MKL14Z64VFT4R equivalent, this page delivers verified technical context, low-power mode behavior, peripheral adder currents, QFN-48 package mapping, and validated alternative MCUs for migration or sourcing continuity.
Technical Context
The MKL14Z64VFT4R implements a tightly coupled Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB), supporting up to 48 MHz in Run mode and down to 4 MHz in Very-Low-Power Run (VLPR) mode. Its clock system includes MCG with FEI/FBE/BLPI/BLPE modes, dual crystal oscillators (32 kHz and 3–32 MHz), and internal 4 MHz/32 kHz IRC sources.
Power management features nine low-power modes - including VLLS0 (0.12 µA typ.), LLS (1.68 µA typ.), and VLPS (3.75 µA typ.) - with full state retention, 4 µs wakeup from VLPS, and configurable peripheral clock gating. Peripheral adders (e.g., IADC = 366 µA, IRTC = 357 nA @25°C) enable precise low-power budgeting.

FAQ
What is the maximum operating frequency and core type of the MKL14Z64VFT4R?
The MKL14Z64VFT4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal Run mode. It achieves 1.25 DMIPS/MHz performance and supports lower-frequency operation (down to 4 MHz) in Very-Low-Power Run (VLPR) mode to optimize energy efficiency. The MKL14Z64VFT4R uses a 90 nm TFS process with integrated power gating to maintain performance while minimizing dynamic and static power consumption.
Does the MKL14Z64VFT4R support USB or CAN interfaces?
No, the MKL14Z64VFT4R does not include native USB or CAN peripherals. Its communication interfaces consist of two UART modules (one low-power), two I²C modules, and two SPI modules. For USB connectivity, designers should consider the pin-compatible MKL26Z128VLH4, which adds USB OTG. CAN is not supported in any KL14 variant; migration to Kinetis K2x or S32K families is required for CAN FD capability. The MKL14Z64VFT4R remains optimized for UART/I²C/SPI-based sensor and control networks.
What are the lowest power consumption modes available on the MKL14Z64VFT4R?
The MKL14Z64VFT4R supports nine low-power modes, with VLLS0 (Very-Low-Leakage Stop Mode 0) delivering the lowest current: 0.12 µA typical at 25°C when PORPO = 1 and brownout disabled. Other ultra-low modes include VLLS3 (1.22 µA typ.), LLS (1.68 µA typ.), and VLPS (3.75 µA typ.), all retaining full register and RAM state. Wakeup from VLPS occurs in 4 µs, enabling rapid response to external interrupts while preserving energy. These values are measured at 3.0 V and confirmed in the official KL14P80M48SF0 datasheet Rev 5.
How many GPIOs does the MKL14Z64VFT4R provide, and what package is used?
The MKL14Z64VFT4R is housed in a 48-pin QFN (VFT4) package measuring 7 mm × 7 mm × 1 mm with 0.5 mm pitch and an exposed thermal pad. It provides 40 general-purpose I/O pins, mapped across PORTA through PORTD, each supporting interrupt-on-change, configurable pull-up/pull-down (20–50 kΩ), and multiple alternate functions (UART, I²C, SPI, TPM, ADC). Pin assignments are fully documented in Section 5.2 ("KL14 pinouts") of the KL14P80M48SF0 datasheet.
Is the MKL14Z64VFT4R still in active production and supported by NXP?
Yes, the MKL14Z64VFT4R remains actively manufactured and supported by NXP Semiconductors. It is listed in NXP's official product longevity program with guaranteed minimum availability through 2028. All documentation - including the KL14P80M48SF0 Reference Manual (RM1), Data Sheet (DS1), and errata - is publicly accessible on nxp.com. NXP continues to provide software development tools (MCUXpresso SDK, IDE, and configuration utilities) and security updates for the Kinetis KL14 family, ensuring long-term design viability for MKL14Z64VFT4R-based products.
