AT91SAM9G15-CU

The AT91SAM9G15-CU is a SMART 400MHz 32-bit Embedded Microprocessor unit based on ARM926EJ-S processor. This MPU integrates a rich set of peripherals to support embedded industrial applications that require advanced user interfaces and high-speed communication. The SAM9G15 features a graphics LCD controller with 4-layer overlay and 2D acceleration and a 10-bit ADC that supports 4-wire/5-wire resistive touchscreen panels. Multiple communication interfaces include a soft modem supporting exclusively the Conexant SmartDAA line driver, HS USB Host and Device and FS USB Host with dedicated on-chip transceivers, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I²S and TWIs. The 10-layer bus matrix coupled with multiple DMA channels ensures uninterrupted data transfers with minimal processor overhead. The external bus interface incorporates controllers for 4-bank and 8-bank DDR2/LPDDR, SDRAM/LPSDRAM, static memories.
