Product details
Overview
MKL15Z64VLK4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in 80-pin LQFP package, featuring 64 KB flash, 8 KB SRAM, and 70 GPIOs. It delivers ultra-low-power operation down to 0.31 µA in VLLS0 mode with full state retention, supports 16-bit SAR ADC and 12-bit DAC, and targets battery-powered industrial sensors and portable HMI devices.
For engineers reviewing the MKL15Z64VLK4 datasheet, MKL15Z64VLK4 pinout, MKL15Z64VLK4 application, or MKL15Z64VLK4 equivalent, key selection criteria include its 80-pin LQFP footprint, -40°C to +105°C operating range, dual UART/I²C/SPI interfaces, low-power timer architecture, and compatibility with Kinetis L-family toolchains and software stacks.
Technical Context
The MKL15Z64VLK4 implements an ARM Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB), executing from zero-wait-state flash memory. Its clock system integrates MCG with FEI/BLPI/PEE modes, supporting internal 4 MHz/32 kHz IRC and external 32 kHz–32 MHz crystals.
Power management includes nine low-power modes (VLPR, VLPS, LLS, VLLS0–3), dynamic clock gating, and voltage regulation optimized for 1.71–3.6 V supply. Analog subsystem comprises 16-bit ADC with 16-channel input multiplexer, 12-bit DAC, and comparator with integrated 6-bit DAC reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L071KBT6 | 32 MHz Cortex-M0+, 128 KB flash, 20 KB RAM, 36 GPIOs in 32-pin LQFP - lower I/O count, no integrated TSI, higher active current (110 µA/MHz). | Better suited for compact, cost-sensitive designs where touch interface is unnecessary and flash headroom is critical. | Select when prioritizing code size margin over peripheral richness and ultra-low standby current. |
| KL26Z128VLH4 | 48 MHz Cortex-M0+, 128 KB flash, 16 KB RAM, 54 GPIOs in 64-pin LQFP - same family architecture but larger memory and smaller package; lacks VLLS0 sub-µA mode. | Ideal for space-constrained applications needing more memory but tolerating higher stop-mode current (2.1 µA vs. 0.31 µA). | Choose when board area is limited and design requires >64 KB flash without upgrading to 80-pin footprint. |
Compared with MKL15Z64VLK4, STM32L071KBT6 trades I/O count and ultra-low-power capability for smaller footprint and higher flash density, while KL26Z128VLH4 offers memory scalability in a denser package but sacrifices the deepest low-power state essential for decade-long battery operation.

FAQ
What is the maximum operating frequency of the MKL15Z64VLK4?
The MKL15Z64VLK4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode, with system and bus clocks scalable to 24 MHz. In very-low-power run (VLPR) mode, the core operates up to 4 MHz to minimize dynamic power consumption while retaining full functionality.
Does the MKL15Z64VLK4 support hardware touch sensing?
Yes, the MKL15Z64VLK4 includes a dedicated Touch Sensing Interface (TSI) module capable of supporting up to 16 capacitive touch electrodes with automatic calibration and noise immunity features - eliminating the need for external touch controller ICs in HMI designs.
What are the low-power mode current specifications for MKL15Z64VLK4?
In VLLS0 mode, MKL15Z64VLK4 draws as little as 0.31 µA (typical at 25°C) with full RAM and register retention and 4 µs wakeup time. Other modes include VLLS1 (0.58 µA), LLS (1.68 µA), and VLPS (3.75 µA), all verified across -40°C to +105°C ambient conditions.
Which communication interfaces are integrated into the MKL15Z64VLK4?
The MKL15Z64VLK4 integrates two UART modules (including one low-power UART), two I²C modules, two SPI modules, and a dedicated low-power timer (LPTMR). These interfaces support concurrent operation - for example, UART for diagnostics, I²C for display, and SPI for sensor data acquisition.
Is the MKL15Z64VLK4 pin-compatible with other Kinetis L-series MCUs?
No, MKL15Z64VLK4 is not pin-compatible with other Kinetis L-series variants due to its 80-pin LQFP package - distinct from 32-pin QFN (FM), 48-pin QFN (FT), or 64-pin LQFP (LH) options. However, it shares identical peripheral registers, memory map, and software APIs with the KL15 family for seamless firmware portability.
