Overview

The MKL17Z256VFM4 is an ultra-low-power 32-bit microcontroller from the Kinetis KL1 series, powered by an ARM Cortex-M0+ core running up to 48MHz. It features 256KB of Flash and 32KB of RAM, providing a high memory-to-pin-count ratio in a compact 32-QFN package. This MCU integrates a 16-bit ADC, a 12-bit DAC, and specialized FlexIO peripherals to offload the CPU in power-sensitive designs.

Why Choose This Part

The part offers a significant memory density for its size, combining 256KB Flash with 32KB RAM in a 32-pin package. Its ultra-low-power architecture includes a Bit Manipulation Engine (BME) for efficient peripheral bitwise operations and a DMA controller that reduces CPU overhead. Designers benefit from a wide operating voltage range of 1.71V to 3.6V, supporting varied power supply configurations.

Applications

Battery-Powered IoT Nodes
Utilizes low-leakage wakeup units and multiple deep-sleep modes to extend battery life in remote monitoring applications.
Smart Sensing Systems
Employs the high-resolution 16-bit ADC and internal voltage reference for precision analog data acquisition.
Consumer Wearables
The small 5x5mm QFN footprint and low active current (5.76mA at 48MHz) suit compact, portable electronics.
Communication Interface Bridges
Uses FlexIO to emulate various serial protocols, such as UART or SPI, providing flexibility for legacy system integration.
