AT91SAM9G45 概述

The AT91SAM9G45 embedded microprocessor is based on the integration of an ARM926EJ-S processor with fast SRAM, and a wide range of peripherals. The AT91SAM9G45 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 64 KBytes 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.
