chip instruction


based on the arm926ej-s processor and running at 400mhz, the sam9g35 integrates advanced user interface and high-speed communication peripherals. it features an advanced graphics lcd controller with 4-layer overlay offering picture-in-picture, alpha-blending, scaling, rotation and color conversion and a 10-bit adc that supports 4- or 5-wire resistive touchscreen panels. multiple communication interfaces include a soft modem supporting exclusively the conexant smartdaa line driver, usb host and device and fs usb host with on-chip transceivers, 10/100 ethernet mac, two hs sdcard/sdio/mmc interfaces, usarts, spis, i2s and twis. 2 x 8 dma channels and dedicated dmas for the communication and interface peripherals ensure uninterrupted data transfers with minimal processor overhead. the external bus interface incorporates controllers offering support for 8-bank ddr2/lpddr, sdram/lpsdram, static memories, as well as specific circuitry for mlc/slc nand flash with integrated ecc up to 24 bits. the sam9g35 is available in a 217-ball bga package with 0.8mm ball pitch.
