K70: Low-Power MCU with Floating Point Unit, Graphic LCD, Ethernet, USB, Encryption and Tamper Detect
Kinetis is the most scalable portfolio of low power, mixedsignal ARM.Cortex™-M4 MCUs in the industry. Phase 1 of the portfolio consists of five MCU families with over 200 pin-,peripheral- and software-compatible devices. Each family offers excellent performance, memory and feature scalability with common peripherals, memory maps, and packages providing easy migration both within and between families.
Kinetis MCUs are built from Freescale’s innovative 90nm Thin Film Storage (TFS) flash technology with unique FlexMemory. Kinetis MCU families combine the latest lowpower innovations and high performance, high precision mixed-signal capability with a broad range of connectivity, human-machine interface, and safety & security peripherals.Kinetis MCUs are supported by a market-leading enablement bundle from Freescale and numerous ARM 3rd party ecosystem partners.
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.
All Kinetis families include a ...
