　　Kinetis K60: Low-Power MCU with optional Floating Point Unit, Ethernet, USB, Encryption and Tamper Detect

　　Kinetis is the most scalable portfolio of low power, mixedsignal ARMRCortex™-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 K60 MCU family includes IEEE 1588 Ethernet, full- and high-speed USB 2.0 On-The-Go with device charger detect capability, hardware encryption and tamper detection capabilities. Devices start from 256 KB of flash in 100LQFP packages extending up to 1 MB in a 256MAPBGA package with a rich suite of analog, communication, timing and control peripherals.

　　High memory density K60 family devices include an optional single precision floating point unit, NAND flash controller and DRAM controller.
