An internal MHz multi-layer bus architecture associated with 37 DMA channels, a dual external bus interface and distributed memory including a 64KByte SRAM which can be configured as a tightly coupled memory TCM sustains the high bandwidth required by the processor and the high speed peripherals. This feature completely eliminates the need for any external level shifters. In addition it supports ball pitch package for low cost PCB manufacturing. The AT91SAM9G45 power management controller features efficient clock gating and a battery backup section minimizing power consumption in active and standby modes. The ISI allows the user to program the same component order as the sensor, reducing software treatments to restore the right format.

Each Master has its own decoder, which can be defined specifically for each master. In order to simplify the addressing, all the masters have the same decodings All the Masters can normally access all the Slaves.

However, some paths do not make sense, such as allowing access from the Ethernet MAC to the internal peripherals. Memories Figure Embedded Memories 7. After reset and until the Remap Command is performed, the four SRAM blocks are contiguous and only accessible at address 0x Note: All the memory blocks can always be seen at their specified base addresses that are not concerned by these parameters.
