Product details

48 MHz Cortex-M0+ — enough for sensor fusion, not for heavy DSP

The NXP MKL17Z256VFT4R is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL1 series, clocked at 48 MHz with 256 KB Flash and 32 KB RAM. It carries 40 GPIO, I²C, SPI, UART/USART, and LINbus connectivity, plus an 18-channel 16-bit ADC and a 12-bit DAC.

Memory and peripheral budget for a single-application image

The 32 KB RAM supports moderate buffering; if your application needs a large frame buffer or extensive data logging, you will bump into the ceiling. The 18-channel 16-bit ADC and single 12-bit DAC cover analog front-end needs without an external converter.

Package and mounting — 48-QFN with exposed pad

The exposed pad is the primary ground connection — ensure the PCB layout ties it to the ground plane with adequate vias.

Frequently asked questions

What is the closest pin-compatible alternative to MKL17Z256VFT4R?

The base product number MKL17Z256 covers several density and package variants within the Kinetis KL1 family. For a pin-compatible alternative, look at other MKL17Z256 devices in the same 48-QFN footprint — the Flash and RAM sizes may differ, but the pinout is consistent across the series.

What is MKL17Z256VFT4R's listed speed?

The core runs at 48 MHz, which is the maximum clock for this Cortex-M0+ implementation in the Kinetis KL1 series.
