DATASHEET
Description
The Atmel^® | SMART ARM926EJ-S^™-based SAM9G46 features the frequently
requested combination of user interface functionality and high data rate
connectivity, including LCD Controller, resistive touchscreen, camera interface,
audio, Ethernet 10/100 and high speed USB and SDIO. With the processor
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.
