AT91SAM9261S 概述

The AT91SAM9261S is a complete system-on-chip built around the ARM926EJ-S ARM Thumb processor with an extended DSP instruction set and Jazelle Java accelerator. The AT91SAM9261S achieves 210 MIPS at 190 MHz.

The AT91SAM9261S is an optimized host processor for applications with an LCD display. Its integrated LCD controller supports BW and up to 16M color, active and passive LCD displays. The 16 Kbyte integrated SRAM can be configured as a frame buffer minimizing the impact for LCD refresh on the overall processor performance. The External Bus Interface incorporates controllers for synchronous DRAM (SDRAM) and Static memories and features specific interface circuitry for CompactFlash and NAND Flash.

The AT91SAM9261S integrates a ROM-based Boot Loader supporting code shadowing from, for example, external DataFlash® into external SDRAM. The software controlled Power Management Controller (PMC) keeps system power consumption to a minimum by selectively enabling/disabling the processor and various peripherals and adjustment of the operating frequency.

The AT91SAM9261S also benefits from the integration of a wide range of debug features including JTAG-ICE, a dedicated UART debug channel (DBGU) and an embedded real time trace. This enables the development and debug of all applications, especially those with real-time constraints.
