NXP Semiconductors MK26FN2M0VLQ18

Overview

MK26FN2M0VLQ18 from NXP Semiconductors is a 180 MHz ARM® Cortex®-M4F microcontroller with 2 MB flash, 256 KB SRAM, dual USB (HS/FS/LS OTG), two CAN interfaces, and operation across –40°C to 105°C. It integrates dual 16-bit SAR ADCs, four analog comparators with 6-bit DACs, and supports FlexBus/SDRAM for industrial HMI and motor control applications.

For engineers reviewing the MK26FN2M0VLQ18 datasheet, MK26FN2M0VLQ18 pinout, MK26FN2M0VLQ18 application, or MK26FN2M0VLQ18 equivalent, key selection criteria include high-speed run mode (180 MHz), VLLS0 stop-mode current (0.55 µA @ –40–25°C), USB HS PHY integration, FlexMemory support, and 144-pin LQFP package compatibility with industrial thermal and ESD requirements.

Technical Context

The MK26FN2M0VLQ18 implements an ARM Cortex-M4F core with single-precision FPU and DSP extensions, operating at up to 180 MHz in High-Speed Run mode. Its memory subsystem includes 2 MB on-chip flash (non-FlexMemory variant), 256 KB SRAM, and optional FlexNVM/FlexRAM on other variants - though MK26FN2M0VLQ18 is confirmed as non-FlexMemory per ordering table.

Peripheral architecture features dual USB controllers (one with integrated HS PHY), two CAN 2.0B modules, four I²C, three SPI, five UART + LPUART0, SDHC, I²S, TSI, and extensive low-power timer resources including TPM/PIT/LPTMR. Clocking supports 3–32 MHz crystal, 32 kHz RTC oscillator, and 48 MHz IRC, with MCG configurable in PEE/BLPE/FEI modes.

FAQ

What is the maximum operating frequency of the MK26FN2M0VLQ18 core?

The MK26FN2M0VLQ18 features an ARM Cortex-M4F core rated for up to 180 MHz in High-Speed Run mode. This frequency is achievable with proper power supply decoupling, thermal management, and clock configuration (e.g., MCG in PEE mode with 32 MHz crystal and PLL multiplication). The core maintains full DSP instruction and single-precision floating-point unit functionality at this speed.

Does the MK26FN2M0VLQ18 include an integrated USB high-speed physical layer?

Yes, the MK26FN2M0VLQ18 integrates a USB high-speed (480 Mbps) PHY on die for its USB0 controller. This eliminates the need for an external transceiver in USB device or host applications. USB1 supports full-speed and low-speed OTG but requires an external pull-up resistor and does not include an HS PHY.

What is the minimum supply voltage for reliable flash programming on the MK26FN2M0VLQ18?

The MK26FN2M0VLQ18 requires a minimum VDD of 1.71 V for flash write/erase operations, as specified in its electrical characteristics. Programming must occur within the full 1.71–3.6 V operating range, and voltage must remain stable during the entire flash command sequence to prevent corruption.

How many analog-to-digital converters does the MK26FN2M0VLQ18 support, and what is their resolution?

The MK26FN2M0VLQ18 integrates two independent 16-bit successive approximation register (SAR) ADCs, each capable of up to 1 MSPS sampling rate. Both ADCs support hardware averaging, programmable conversion triggers, and flexible input channel mapping across GPIO pins.

Is the MK26FN2M0VLQ18 pin-compatible with other Kinetis K26 variants in the same package?

Yes, the MK26FN2M0VLQ18 shares identical pinout and electrical characteristics with other K26 devices in the 144-pin LQFP package (e.g., MK26FN2M0VMD18), including identical power, ground, GPIO, USB, CAN, and clock pin assignments. Firmware and PCB layout are interchangeable across these variants.
