The SAM9G35 is a member of the series of 400 MHz ARM926EJ-S embedded MPUs that support high bandwidth communication and advanced user interfaces and are optimized for industrial applications such as building automation, data loggers, POS terminals, alarm systems and medical equipment. The SAM9G35 features an advanced graphics LCD controller with 4-layer overlay and 2D acceleration (picture-in-picture, alpha-blending, scaling, rotation, color conversion) and a 10-bit ADC that supports 4-wire or 5-wire resistive touch screen panels. Multiple communication interfaces include a soft modem supporting exclusively the Conexant SmartDAA line driver, HS USB Device and Host, FS USB Host, 10/100 Ethernet MAC, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S and TWIs. The 10-layer bus matrix coupled with 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 4-bank and 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 0.8 mm ball pitch.
