AT91SAM9M11

Description

The AT91SAM9M11 is a multimedia enabled mid-range ARM926-based embedded MPU run-

ning at 400MHz, combining user interfaces, video playback and connectivity. It includes

hardware video decoder, LCD Controller, resistive touchscreen, camera interface, audio, Ether-

net 10/100 and high speed USB and SDIO.

The hardware video decoder supports H.264, MPEG-4, MPEG-2, VC-1, H.263 up to D1 (720 x

576 pixels) or WVGA (800 x 480) resolutions at 30 frames per second (fps). The SAM9M11 also

provides hardware image post-processing, such as image scaling, color conversion and image

rotation.

The AT91SAM9M11 supports the latest generation of DDR2 and NAND Flash memory inter-

faces for program and data storage. An internal 133 MHz multi-layer bus architecture associated

with 39 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.

On-chip hardware accelerators with DMA support enable high-speed data encryption and

authentication of the transferred data or application. Supported standards are up to 256-bit AES,

FIPS PUB 46-3 compliant TDES and FIPS Publication 180-2 compliant SHA1 and SHA256. A

True Random Number Generator is embedded for key generation and exchange protocols.

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 AT91SAM9M11 power management controller features efficient clock gating and a battery

backup section minimizing power consumption in active and standby modes.

The AT91SAM9M11 device is particularly well suited for media-rich displays and control panels

in home and commercial buildings, POS terminals, entertainment systems, internet appliances

and medical applications.
