Product details

The NXP MKL26Z128VFT4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL2 series, clocked at 48 MHz with 128 KB Flash and 16 KB RAM. It integrates a USB OTG controller, I²C, SPI, UART, and a 16-bit ADC plus 12-bit DAC — enough peripheral set for a USB-connected sensor hub or a human-machine interface node. The 48-VFQFN exposed-pad package (7x7 mm) keeps the board footprint tight, and the -40 to 105 °C operating range lets it sit in an outdoor telecom cabinet or an industrial enclosure without active cooling.

48 MHz Cortex-M0+ — what it buys you

The 48 MHz core handles a USB-OTG control loop or Modbus gateway with margin. It is not a DSP-class core.

128 KB Flash holds a USB stack, a lightweight RTOS, and application code for a single-function device. The 16 KB RAM is tight for a large frame buffer.

The Kinetis KL2 family is a mature portfolio; NXP has not announced a direct replacement.

Frequently asked questions

What is the pinout and package of MKL26Z128VFT4?

The MKL26Z128VFT4 comes in a 48-VFQFN exposed-pad package (7x7 mm, 0.5 mm pitch). It has 36 I/O. The center pad must be soldered to a ground plane with thermal vias for heat dissipation.

What is the operating voltage range of MKL26Z128VFT4?

The supply range is 1.71 V to 3.6 V on Vcc/Vdd. On-chip brown-out detect and POR handle reset sequencing.

What are the key differences between MKL26Z128VFT4 and MKL26Z256VFT4?

The MKL26Z256VFT4 doubles the Flash to 256 KB and RAM to 32 KB. Everything else — package, pinout, peripherals, temperature range — is identical. If your firmware fits in 128 KB, the MKL26Z128VFT4 is the cost-optimized choice.

Where can I buy MKL26Z128VFT4 and what is its price?

The MKL26Z128VFT4 is available through independent distribution. Pricing and stock are confirmed at quote time against an RFQ — submit a request for current availability and a firm quote.
