ATMEL  AT91SAM9X35-CU  微控制器, 32位, ARM9, 400 MHz, 32 KB, 32 KB, 217 引脚, BGA

The is a SMART 400MHz 32-bit Embedded Microprocessor Unit based on ARM926EJ-S processor. 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 and a 10-bit ADC that supports 4-wire or 5-wire resistive touchscreen 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.
