Product details
Overview
MKL15Z64VLH4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in 64-pin LQFP package, featuring 64 KB flash, 8 KB SRAM, 16-bit SAR ADC, 12-bit DAC, and ultra-low-power operation down to 0.31 µA in VLLS0 mode. It integrates two UARTs, two I²C, two SPI, TSI touch interface, RTC, and six-channel TPM - designed for battery-powered industrial sensors and portable HMI systems.
For engineers reviewing the MKL15Z64VLH4 datasheet, MKL15Z64VLH4 pinout, MKL15Z64VLH4 application, or MKL15Z64VLH4 equivalent, this page delivers verified specifications, validated low-power timing behavior, confirmed LQFP-64 mechanical dimensions, and cross-referenced alternatives for entry-level 32-bit MCU selection in temperature-critical (-40°C to 105°C) embedded designs.
Technical Context
The MKL15Z64VLH4 implements an ARM Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB), operating at up to 48 MHz in Run mode or 4 MHz in Very-Low-Power Run (VLPR) mode. Its clock system includes MCG with FEI/FBE/BLPI/BLPE modes, supporting internal 4 MHz/32 kHz IRC and external 32 kHz–32 MHz crystals.
Power management comprises nine low-power modes (VLPR, VLPS, LLS, VLLS0–3), with full state retention at 2 µA static current and 4 µs wakeup from VLPS. Memory subsystem uses zero-wait-state flash controller and 90 nm TFS process for energy efficiency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKL25Z64VLH4 | Same 64-pin LQFP package, but adds USB OTG controller and higher flash endurance (100k cycles vs. 50k); 12-bit ADC only. | Better suited for host-peripheral USB connectivity; less optimal for high-resolution analog acquisition. | Select when USB device/host capability is required and 16-bit ADC is not critical. |
| STM32L053R8T6 | 32-pin LQFP, 64 KB flash, 8 KB RAM, but ARM Cortex-M0, no TSI, 12-bit ADC only, lower max temp (85°C). | Lower pin count and temperature grade limit use in extended industrial environments. | Consider for cost-sensitive, space-constrained designs where touch interface and 105°C operation are unnecessary. |
Compared with MKL15Z64VLH4, MKL25Z64VLH4 adds USB at the expense of 16-bit ADC resolution, while STM32L053R8T6 reduces footprint and thermal capability but lowers unit cost - choice depends on whether USB, analog precision, or PCB area is the dominant constraint.

FAQ
What is the maximum operating temperature range for the MKL15Z64VLH4?
The MKL15Z64VLH4 is rated for ambient temperatures from -40°C to +105°C, making it suitable for under-hood automotive applications, industrial control cabinets, and outdoor sensor deployments where thermal extremes are expected. This specification is validated per JEDEC JESD22-A104 and confirmed in Table 4 and Section 2.2.1 of the official datasheet KL15P80M48SF0.
Does the MKL15Z64VLH4 support USB connectivity?
No, the MKL15Z64VLH4 does not include a USB controller. It provides two UARTs, two I²C modules, and two SPI interfaces for serial communication. For USB-capable alternatives in the same Kinetis L family, consider the MKL25Z64VLH4, which adds full-speed USB OTG while retaining the same 64-pin LQFP package and core architecture.
What is the lowest power consumption mode available on the MKL15Z64VLH4?
The MKL15Z64VLH4 achieves its lowest active power state in Very-Low-Leakage Stop Mode 0 (VLLS0), consuming just 0.31 µA at 25°C with full RAM retention and wake-from-pin capability. This mode is enabled via SMC_STOPCTRL[PORPO]=0 and is documented in Table 9 of the KL15P80M48SF0 datasheet as the most aggressive low-power configuration for long-term battery operation.
How many GPIO pins does the MKL15Z64VLH4 provide?
The MKL15Z64VLH4 offers 54 general-purpose I/O pins across four ports (PTA, PTB, PTC, PTD), as specified in the Ordering Information table and confirmed in Section 5.2 "KL15 pinouts" of the KL15P80M48SF0 datasheet. All GPIOs support interrupt-on-change, configurable pull-up/down resistors (20–50 kΩ), and multiple drive strengths.
Is the MKL15Z64VLH4 pin-compatible with other Kinetis L-series MCUs?
The MKL15Z64VLH4 is pin-compatible within the MKL15ZxxVLH4 variant group (e.g., MKL15Z32VLH4, MKL15Z128VLH4), sharing identical 64-pin LQFP mechanical layout and signal mapping. However, it is not pin-compatible with other package variants (e.g., VFM4, VFT4, VLK4) due to differing pin counts and assignments - always verify signal multiplexing using the KL15 Signal Multiplexing table before substitution.
