Overview

The MKL27Z256VMP4 is an ultra-low-power ARM Cortex-M0+ microcontroller from the Kinetis KL2x family, designed for battery-operated applications requiring USB connectivity. It features 256KB of Flash and 32KB of RAM in a compact 5x5mm 64-MAPBGA package, operating at speeds up to 48MHz. A key feature is its crystal-less USB 2.0 full-speed controller, which reduces system cost and PCB footprint.

Why Choose This Part

It offers a high-density 256KB Flash memory in a very small 64-pin BGA footprint, catering to space-constrained designs. The device simplifies BOM requirements through an integrated ROM bootloader for easy firmware updates and an internal voltage reference for the 16-bit ADC.

Applications

Battery-Powered IoT Sensors
Utilizes very low power run modes (54uA/MHz) and multiple deep sleep states to extend battery life in remote sensing applications.
USB Human Interface Devices
The integrated USB FS 2.0 device controller supports crystal-less operation, making it ideal for compact peripherals like mice, keyboards, and game controllers.
Portable Medical Devices
Integrated 16-bit ADC and 12-bit DAC provide precise analog interfacing for health monitoring equipment in a small form factor.
Smart Home Controllers
Features FlexIO for emulating custom serial protocols and a Bit Manipulation Engine for efficient peripheral control.
