6221IS–ATARM–12-Aug-08
The AT91SAM9260 is based on the integration of an ARM926EJ-S processor with fast ROM
and RAM memories and a wide range of peripherals.
The AT91SAM9260 embeds an Ethernet MAC, one USB Device Port, and a USB Host control-
ler. It also integrates several standard peripherals, such as the USART, SPI, TWI, Timer
Counters, Synchronous Serial Controller, ADC and MultiMedia Card Interface.
The AT91SAM9260 is architectured on a 6-layer matrix, allowing a maximum internal bandwidth
of six 32-bit buses. It also features an External Bus Interface capable of interfacing with a wide
range of memory devices.
The block diagram shows all the features for the 217-LFBGA package. Some functions are not
accessible in the 208-pin PQFP package and the unavailable pins are highlighted in
