1. Description
The ARM926EJ-S based SAM9G46 features the frequently requested combination of user inter-
face 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 SAM9G46 has the
performance and bandwidth to the network or local storage media to provide an adequate user
experience.
The SAM9G46 supports the latest generation of DDR2 and NAND Flash memory interfaces 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 that 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 SAM9G46 power management controller features efficient clock gating and a battery
backup section minimizing power consumption in active and standby modes.
