The Kinetis KL02 chip-scale package (CSP) is the entry point into the low-power Kinetis L series MCUs based on the ARM® Cortex®-M0+-based processor and is one of the world's smallest ARM Powered® MCUs. Available in the ultra-small 1.9 mm x 2.0 mm wafer level chip-scale package, the KL02 CSP (MKL02Z32CAF4R) drastically reduces board space while retaining rich MCU feature integration, and consumes 25 percent less PCB area, while delivering 60 percent more GPIO than the nearest competing MCU.
