Description
The ARM926EJ-S based SAM9G45 features the frequently demanded combination of user interface function-
ality and high data rate connectivity, including LCD Controller, resistive touch-screen, camera interface, audio,
Ethernet 10/100 and high speed USB and SDIO. With the processor running at 400 MHz and multiple 100+
Mbps data rate peripherals, the SAM9G45 has the performance and bandwidth to the network or local storage
media to provide an adequate user experience.
The SAM9G45 supports DDR2 and NAND Flash memory 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 dis-
tributed 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 sup-
ports 0.8 ball pitch package for low cost PCB manufacturing.
The SAM9G45 power management controller features efficient clock gating and a battery backup section min-
imizing power consumption in active and standby modes.
