Kinetis Mini MCUs Wafer-Level Chip-Scale Package Portfolio

by donpedro

Driving innovation with tiny, industry-leading packages.


Kinetis mini MCUs are Freescale’s smallest, ARM Powered® devices, being shipped in a variety of wafer-level chip-scale packages (WLCSPs). These MCUs are offered in industry-leading miniature packages, providing massive design potential for today’s embedded designers. Freescale’s WLCSP technology development has enabled smaller packages, with greater functionality, than previously seen in the market.
The Kinetis mini portfolio, which to-date has globally shipped in the millions, now include the Kinetis KL03 CSP—the world’s smallest ARM-based MCU—shrinking its predecessor by 15%, further enabling customers to reduce the size of their embedded applications.

Target Applications

• Intelligent wearables
• Portable medical monitoring
• Remote monitoring
• Tablet and phone accessories

Did You Know?

• 19,000 Kinetis mini MCUs fit on a piece of paper (U.S. letter size).
• 23,000 Kinetis mini MCUs fill a golf ball.
• 3.2 million Kinetis mini MCUs fill a soccer ball.

Kinetis Wafer-Level Chip-Scale MCUs

Technical Features

The Kinetis mini portfolio of products are assembled at the wafer level, creating the smallest form-factor package possible. They require no wire bonds or substrate interposers and use solder balls, directly attached to the silicon, to make the PCB connection.
Please refer to our Wafer-level Chipscale Package (AN3846) Application Note on for more detailed technical information.
