The Kinetis KL03 chip-scale package (CSP) MCU is the world's smallest ARM Powered® MCU designed to support the latest innovation in smart, small devices. Available in the ultra-small 1.6 mm x 2.0 mm wafer-level CSP, the KL03 CSP (MKL03Z32CAF4R) reduces even more board space while integrating even more rich MCU features than previously seen in the market. The Kinetis KL03 CSP MCU consumes 35 percent less PCB area, while delivering 60 percent more GPIO than the nearest competing MCU.
