AT91SAM9261S
1. Description
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. It 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 con-
trollers 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 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 AT91SAM9261S 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.
