Detailed Description

The graphics LCD controller features 4-layer overlay and 2D acceleration (picture-in-picture, alpha-blending, scaling, rotation, color conversion), and a 10-bit ADC that supports 4- or 5-wire resistive touchscreen panels. Additional interfaces include a soft modem supporting exclusively the Conexant SmartDAA line driver, High Speed USB Device and Host, Full Speed USB Host, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S and TWIs. A multi-layer bus matrix associated with 2 x 8 central DMA channels as well as dedicated DMAs support the high-speed connectivity. The external bus interface incorporates controllers for 8-bank DDR2/LPDDR, SDRAM/LPSDRAM, static memories, and specific circuitry for MLC/SLC NAND Flash with integrated ECC. The SAM9X35 is available in a 217-ball BGA package with 0.8mm ball pitch.
