Product details

The NXP MKL17Z128VFM4 is a 32-bit ARM Cortex-M0+ microcontroller from the Kinetis KL1 series, clocked at 48 MHz with 128 KB Flash and 32 KB SRAM. It includes a 16-bit ADC and 12-bit DAC.

The 32-QFN with exposed pad (5x5 mm) requires a thermal via pattern.

Peripherals and I/O

28 general-purpose I/O lines, with I²C, SPI, UART, and LINbus connectivity. The 11-channel 16-bit ADC and single 12-bit DAC are included. Internal oscillator is factory-trimmed.

ROHS3 compliant. For volume commitments or BOM freeze planning, the active status gives a multi-year procurement window.

Frequently asked questions

Is MKL17Z128VFM4 a replacement for MKL17Z128VLH4?

The MKL17Z128VLH4 is a 64-LQFP variant of the same die; the VFM4 is the 32-QFN package version. They are not pin-compatible — the QFN has fewer I/O (28 vs 54) and a different footprint. Choose the package that matches your board layout.

What is the package size of MKL17Z128VFM4?

It comes in a 32-QFN with exposed pad, 5x5 mm body. The pad must be soldered to a thermal land on the PCB.
