SAM9G46
Atmel | SMART ARM-based Embedded MPU
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.
