AT91SAM9G25-CU 原装 MCU的描述：
Based on the ARM926EJ-S? core, the SAM9G25 is an embedded microprocessor unit, running at 400 MHz and featuring connectivity peripherals, a high data bandwidth architecture and a small footprint package option, making it an optimized solution for industrial applications.
The multi-layer bus matrix is linked to 2 x 8 DMA channels as well as DMAs dedicated to the communication and interface peripherals, ensuring uninterrupted data transfers with minimal processor overhead. Interface peripherals include a camera interface that supports direct connection to the ITU-R BT. 601/656 8-bit mode compliant sensors and up to 12-bit grayscale sensors. Communication peripherals include a soft modem supporting exclusively the Conexant SmartDAA line driver, HS (480 Mbps) USB Host and Device ports with on-chip transceivers, FS USB Host, 10/100 Ethernet MAC, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S, multiple TWIs and 10-bit ADC.
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 SAM9G25 is available in a 217-ball BGA package with 0.8 mm ball pitch, as well as in 247-ball TFBGA and 247-ball VFBGA packages with 0.5 mm ball pitch, making it ideally suited for space-constrained applications.
