SAM9G45
SUMMARY
Description
The ARM926EJ-S based SAM9G45 features the frequently demanded combina-
tion of user interface functionality 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 band-
width 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 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 SAM9G45 power management controller features efficient clock gating and a
battery backup section minimizing power consumption in active and standby
modes.
