Freescale just announced the world’s smallest ARM Powered® MCU. Available in the ultra-small 1.9 mm x 2.0 mm wafer level chip-scale package, the KL02 CSP requires very little board space while retaining MCU feature integration. The KL02 CSP consumes 25 percent less PCB area, yet delivers 60 percent more GPIO than the nearest competing MCU.
The Kinetis KL0 family is the entry point into the low-power Kinetis L series MCUs based on the ARM® Cortex™-M0+ processor, delivering 32-bit performance with class-leading code density, integrated flash memory, precision analog, connectivity and timers.
On the right you see how the chip compares to the first commercial 32-bit processor.
