1. Description
The ARM926EJ-S based SAM9G45 features the frequently demanded combination 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 pro-
cessor running at 400MHz 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 stor-
age. 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 config-
ured 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.
