Hardware Features
The AT91SAM9G45 embedded microprocessor is based on the integration of an ARM926EJ-S
processor with fast SRAM, and a wide range of peripherals. It is designed to provide a high
performance processor solution with a high flexibility for general and multimedia oriented
applications. The internal multi-layer bus architecture associated with a multi-port DDR2, a 32-bit
External Bus Interface and 64KBytes of internal SRAM allows the SAM9G45 to sustain the high
bandwidth required by its high speed peripherals. The AT91SAM9G45 power management (APMC)
features an efficient clock gating which, associated with the ARM926EJ-S low power modes, greatly
reduces power consumption under all conditions of use.
To reduce the overall system cost, the AT91SAM9G45 integrates many hardware peripherals such as
High Speed (480 Mbps) USB Device and Host with transceivers, a 10/100 Mbps Ethernet controller, a
High Speed Multimedia Card interface, an LCD controller supporting STN and TFT displays up to
1280*860, a camera interface and several communication peripherals such as USARTs, Serial
Synchronous Controllers and Two Wire Interface. All these peripherals are DMA oriented, reducing
the CPU overload.
The SBC6245 has a CPU board Mini6245 integrated with AT91SAM9G45 microcontroller, Nand
Flash, EEPROM and DDR2 SDRAM on it, which exposes many of these features to the user
in support of developing specific solutions. The CPU board can be mounted directly onto the
expansion board through two 1.27mm pitch 80-pin expansion connectors. This board is characterized
as follows:
