[原创] Atmel SMART SAM9G10 ARM MCU开发方案

Atmel公司的SMART SAM9G10是集成了ARM926EJ-S ARM Thumb处理器和扩展指令集以及Jazelle Java加速器的完整系统级芯片(SoC),266MHz时的性能达到293MIPS. SoC还集成了LCD控制器,支持黑白和多达16M彩色,有源和无源LCD显示器,主要用在建筑物自动化,家庭娱乐,智能电网,消防和安全系统,家庭显示单元和移动电子学以及视频.本文介绍了SMART SAM9G10主要特性,框图,ARM926EJ-S处理器特性以及评估板SAM9G10-EK2特性,电路图和PCB元件布局图.

The SAM9G10 is a complete system-on-chip built around the ARM926EJ-S ARM Thumb processorwith an extended DSP instruction set and Jazelle Java accelerator. It achieves 293 MIPSat 266 MHz.

The SAM9G10 is an optimized host processor for applications with an LCD display. Its integratedLCD controller supports BW and up to 16M color, active and passive LCD displays. TheExternal Bus Interface incorporates controllers for synchronous DRAM (SDRAM) and Staticmemories and features specific interface circuitry for CompactFlash and NAND Flash.

The SAM9G10 integrates a ROM-based Boot Loader supporting code shadowing from, forexample, external DataFlash® into external SDRAM. The software controlled Power ManagementController (PMC) keeps system power consumption to a minimum by selectivelyenabling/disabling the processor and various peripherals and adjustment of the operatingfrequency.
