The K70 MCU family includes an integrated graphic LCD controller, IEEE

®

 1588 Ethernet MAC, full- and high-speed USB

2.0 On-The-Go with device charger detect capability, hardware encryption and tamper detection capabilities. The K70 is
available with 512 KB or 1 MB of flash memory in 196- and 256-pin MAPBGA packages. Each MCU includes a rich suite
of analog, communication, timing and control peripherals. All K70 family devices include a single precision floating point
unit and NAND flash controller. 256-pin versions include an on-chip DRAM controller for system expansion.

The below figure shows a superset block diagram of the K70 device. Other devices within the family have a subset of the
features.
