DATASHEET

Description

The Atmel® | SMART ARM926EJ-S™-based SAM9G46 embedded

microprocessor unit (eMPU) 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 400 MHz and multiple

100+ Mbps data rate peripherals, the SAM9G46 provides adequate performance

and bandwidth to the network or local storage media.

The SAM9G46 eMPU supports 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 mm 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.
