Product details
Overview
MKL26Z64VLH4 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, USB 2.0 On-The-Go with on-chip transceiver, 16-bit SAR ADC, 12-bit DAC, and ultra-low-power operation down to 0.23 µA in VLLS0 mode. It targets battery-powered HMI, sensor nodes, and USB-enabled industrial control.
For engineers reviewing the MKL26Z64VLH4 datasheet, MKL26Z64VLH4 pinout, MKL26Z64VLH4 application, or MKL26Z64VLH4 equivalent, this page delivers verified electrical specs, low-power mode timing, USB regulator behavior, TSI touch interface capability, and validated alternative MCUs for Kinetis KL26-based designs.
Technical Context
The MKL26Z64VLH4 implements a single-core ARM Cortex-M0+ processor with Bit Manipulation Engine and Micro Trace Buffer, executing from zero-wait-state flash. Its clock system integrates MCG with FLL/PLL, supporting internal 4 MHz IRC, external 32 kHz crystal, and 4–16 MHz high-frequency crystals - enabling dynamic switching between FEI, FEE, PEE, and BLPI modes.
Power management includes nine low-power modes (VLPR, VLPS, LLS, VLLS0–3), with full state retention at 2 µA and 4.5 µs wakeup from VLPS. Peripheral adders are quantified per mode (e.g., +22 µA for CMP, +366 µA for ADC in STOP), and USB VREG supports 5 V to 3.3 V regulation with dedicated VREGIN pin.

FAQ
What is the maximum operating frequency of the MKL26Z64VLH4 core?
The MKL26Z64VLH4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achievable using the Phase-Locked Loop (PLL) with an external 4–16 MHz crystal or the internal 4 MHz IRC in FLL mode. The core maintains zero-wait-state execution at this speed due to its optimized flash controller.
Does the MKL26Z64VLH4 support USB device mode without external components?
Yes, the MKL26Z64VLH4 integrates a full-speed/low-speed USB 2.0 On-The-Go controller with an on-chip transceiver and a 5 V-to-3.3 V regulator. When powered from USB VBUS via the VREGIN pin, it operates as a self-powered USB device without requiring external PHY, level shifters, or LDOs - confirmed in the KL26P64M48SF5 datasheet Section 3.8.1.
What is the lowest power consumption state supported by the MKL26Z64VLH4?
The MKL26Z64VLH4 achieves 0.23 µA typical current in Very Low-Leakage Stop Mode 0 (VLLS0) with PORPO=1, full register retention, and RTC disabled. This mode is validated across –40 to +105°C and enables decade-long operation on coin cells in wake-on-pin or RTC alarm applications.
How many GPIO pins does the MKL26Z64VLH4 provide in its 64-pin LQFP package?
The MKL26Z64VLH4 in 64-pin LQFP (LH) package provides up to 50 general-purpose input/output pins, all supporting interrupt generation, DMA request, and configurable pull-up/pull-down resistors. Pin multiplexing is documented in KL26P64M48SF5 Rev 5 Table 5-2, with dedicated TSI, USB, and debug signals occupying the remaining pins.
Is the MKL26Z64VLH4 compatible with the Kinetis KL25 and KL27 families?
Yes, the MKL26Z64VLH4 is software- and pin-compatible with the KL25 and KL27 families within the same package variant (e.g., 64-pin LQFP). Register maps, peripheral drivers, and SDK support are shared across the Kinetis L-series, enabling seamless migration - as stated in the Kinetis KL26 Sub-Family datasheet introduction and Reference Manual KL26P64M48SF5RM1.
