Description
The AT91SAM9261 is a complete system-on-chip built around the ARM926EJ-S ARM Thumb
processor with an extended DSP instruction set and Jazelle Java accelerator. It achieves 210
MIPS at 190 MHz.
The AT91SAM9261 is an optimized host processor for applications with an LCD display. Its inte-
grated LCD controller supports BW and up to 16M color, active and passive LCD displays. The
160 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 control-
lers for synchronous DRAM (SDRAM) and Static memories and features specific interface
circuitry for CompactFlash and NAND Flash.
The AT91SAM9261 integrates a ROM-based Boot Loader supporting code shadowing from, for
example, external DataFlash into external SDRAM. The software controlled Power Manage-
ment 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 AT91SAM9261 also benefits from the integration of a wide range of debug features includ-
ing 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.
