Freescale adds small ARM-based MCUs in chip-scale packaging

December 12, 2013 // By Graham Prophet
Freescale Semiconductor is extending its Kinetis portfolio of microcontrollers to include Kinetis miniature (mini) MCUs, in a tiny package. Starting at 1.9 x 2 mm, Kinetis mini MCUs use wafer-level chip-scale packaging (WL-CSP packaging) and maintain the scalability and feature rich IP available across the entire Kinetis portfolio.

Freescale’s Kinetis KL02, claimed as the world’s smallest ARM Powered MCU, is included in this category. Leveraging WL-CSP packaging, Kinetis mini MCUs allow designers to dramatically reduce the size of their boards and products, while retaining the performance and features of their end devices. In addition, space-constrained applications that previously couldn’t incorporate an MCU now can be upgraded to become smart applications.
