The AT91SAM9M10 is a multimedia-enabled high-performance ARM926-b
ased embedded MPU running at 400MHz, combining user interfaces, video playback and c
onnectivity. It includes a hardware video decoder, a 2D accelerator, LCD Controller, resistive touchscreen, camera interface, audio, Ethernet 10/100 and high-speed USB and SDIO. The SAM9M10 is targeted at media rich display and control panels in industrial application segments such as home and commercial buildings, POS (Point of Sale) terminals, entertainment systems, Internet appliances and medical.
The AT91SAM9M10 is a multimedia enabled mid-range ARM926-based embedded MPU running at 400MHz, combining user interfaces, video playback and connectivity. It includes hardware video decoder, LCD Controller, resistive touchscreen, camera interface, audio, Ethernet 10/100 and high speed USB and SDIO.
The hardware video decoder supports H.264, MPEG-4, MPEG-2, VC-1, H.263. The SAM9M10 also provides hardware image post-processing, such as image scaling, color conversion and image rotation.
The AT91SAM9M10 supports the latest generation of DDR2 and NAND
Flashmemory interfaces for program and data storage. An internal 133 MHz multi-layer bus architecture associated with 37 DMA channels, a dual external bus interface and distributed memory including a 64-KByte SRAM which can be configured as a tightly coupled memory (
TCM) sustains the high bandwidth required by the processor and the high speed peripherals.
The I/Os support 1.8V or 3.3V operation, which are independently configurable for the memory interface and peripheral I/Os. This feature completely eliminates the need for any external level shifters. In addition it supports 0.8 ball pitch package for low cost PCB manufacturing.
The AT91SAM9M10
powermanagement controller features efficient clock gating and a battery backup section minimizing power consumption in active and standby modes. The AT91SAM9M10 device is pa
