AT91SAM9X35-CU

The SAM9X35 is a member of the series of 400 MHz ARM926EJ-S embedded microprocessor units. This MPU features an extensive peripheral set and high bandwidth architecture for industrial applications that require refined user interfaces and high-speed communication. The SAM9X35 features a 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. Networking/connectivity peripherals include two 2.0A/B compatible Controller Area Network (CAN) interfaces and an IEEE Std 802.3-compatible 10/100 Mbps Ethernet MAC. Multiple communication interfaces include a soft modem supporting exclusively the Conexant SmartDAA line driver, HS USB Device and Host, FS USB Host, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S, TWIs and 10-bit ADC. The 10-layer bus matrix associated with 2 x 8 central DMA channels as well as dedicated DMAs to support the high-speed connectivity peripherals ensure uninterrupted data transfer with minimum processor overhead. The External Bus Interface incorporates controllers 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 SAM9X35 is available in a 217-ball BGA package with 0.8 mm ball pitch.
