Freescale Kinetis K70 microcontroller: Device enriches human-machine-interface applications

The Cortex-M4-based Kinetis K70 microcontroller targets applications that require a sophisticated graphics-LCD user interface, advanced connectivity, and security. The PEG (portable embedded graphical user interface) supports the family, providing a comprehensive visual-layout and -design tool that accelerates design by allowing developers to create GUIs with simple PC-based environments. The 120- and 150-MHz K70 microcontrollers add new features to the K10, K20, and K60 families. These features include a floating-point unit that extends the range of data-acquisition-intensive applications, such as motor drive, audio processing, and digital filtering, by reducing computation time and increasing accuracy. The devices also feature high-speed USB OTG supporting 480-Mbps data transfer. DRAM and NAND-flash controllers enable the connection of DDR, DDR2, and low-power DDR memories and 32-bit NAND memories. The 120-MHz Kinetis K70 microcontroller with as much as 1 Mbyte of flash memory comes in a 256-ball MAPBGA package and sells for $10.09 (10,000).
