Product details
Overview
MKL26Z128VLH4R from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in 64-pin LQFP package, featuring 128 KB flash, 16 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 with full state retention. It targets battery-powered HMI, sensor hubs, and USB-connected industrial edge nodes.
For engineers reviewing the MKL26Z128VLH4R datasheet, MKL26Z128VLH4R pinout, MKL26Z128VLH4R application, or MKL26Z128VLH4R equivalent, this page delivers verified electrical specs, validated low-power behavior across nine operating modes, confirmed USB/ADC/DAC timing compliance, and real-world design context for rapid integration into resource-constrained embedded systems.
Technical Context
The MKL26Z128VLH4R implements a single-core ARM Cortex-M0+ processor with Bit Manipulation Engine and Micro Trace Buffer, executing from zero-wait-state flash memory. Its clock system integrates MCG with multiple sources: internal 4 MHz/32 kHz IRCs, external crystal (3–32 MHz), and PLL for 48 MHz system clock.
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 operation. Peripheral adders-such as 22 µA for CMP, 366 µA for ADC, and 56 µA for 4 MHz IRC in STOP-are quantified per mode and temperature, enabling precise power budgeting.

FAQ
What is the maximum operating frequency of the MKL26Z128VLH4R core?
The MKL26Z128VLH4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achieved using the Phase-Locked Loop (PLL) with an external crystal or internal reference clock. At 48 MHz, the device delivers 1.22 CoreMark/MHz performance while maintaining low power consumption-verified in the KL26P64M48SF5 datasheet under FEI and PEE clock modes.
Does the MKL26Z128VLH4R include a USB transceiver?
Yes, the MKL26Z128VLH4R integrates a full-/low-speed USB 2.0 On-The-Go transceiver with an internal 5 V-to-3.3 V regulator. This eliminates the need for external USB PHY components. The USB_DP and USB_DM pins connect directly to the USB connector, with only 27 Ω series resistors and a 1.5 kΩ pull-up on DP required for full-speed device operation-confirmed in Section 3.8.1 of the KL26P64M48SF5 datasheet.
What is the lowest power consumption mode supported by the MKL26Z128VLH4R?
The MKL26Z128VLH4R achieves its lowest power state in Very Low-Leakage Stop Mode 0 (VLLS0), consuming as little as 0.23 µA at 3.0 V and 25 °C when SMC_STOPCTRL[PORPO] = 1 and full register/SRAM state is retained. Wakeup occurs in under 120 µs, enabling rapid response to external events-values documented in Table 9 of the KL26P64M48SF5 datasheet Rev 5.
How many GPIO pins does the MKL26Z128VLH4R provide in the 64-pin LQFP package?
The MKL26Z128VLH4R in the 64-pin LQFP (VLH4) package provides up to 50 general-purpose input/output pins. These are distributed across PORTA through PORTD and support multiple alternate functions including UART, SPI, I²C, TPM, ADC inputs, and TSI electrodes-explicitly listed in the "Ordering Information" table and "KL26 Signal Multiplexing" section of the KL26P64M48SF5 datasheet.
Is the MKL26Z128VLH4R compatible with other Kinetis L-series MCUs?
Yes, the MKL26Z128VLH4R is pin-compatible and software-compatible with other Kinetis L-family MCUs (e.g., KL25, KL36) and also interoperable with the Kinetis K2x family at the peripheral driver and toolchain level. This compatibility is explicitly stated in the Kinetis KL26 Sub-Family datasheet introduction and enables scalable design reuse across performance and feature tiers without board redesign.
