AT91SAM9261B-CU

The AT91SAM9261B-CU is a complete system-on-chip 32-bit Embedded Microcontroller built around the ARM926EJ-S ARM Thumb processor with an extended DSP instruction set and Jazelle Java accelerator. It achieves 210MIPS at 190MHz. The AT91SAM9261 is an optimized host processor for applications with an LCD display. Its integrated LCD controller supports BW and up to 16M colour, active and passive LCD displays. The 160kB 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. It integrates a ROM-based boot loader supporting code shadowing from, for example, external DataFlash into external SDRAM.
