The K66 sub-family members provide greater performance, memory options up to 2 MB total flash and 256 KB of SRAM, as well as higher peripheral integration with features such as Dual USB and a 10/100 Mbit/s Ethernet MAC. These devices maintain hardware and software compatibility with the existing Kinetis family. This product also offers: • Integration of a High Speed USB Physical Transceiver • Greater performance flexibility with a High Speed Run mode • Smarter peripherals with operation in Stop modes
