19. AT91SAM9260 External Bus Interface
19.1
6221I–ATARM–17-Jul-09
Description
The External Bus Interface (EBI) is designed to ensure the successful data transfer between
several external devices and the embedded Memory Controller of an ARM-based device. The
Static Memory, SDRAM and ECC Controllers are all featured external Memory Controllers on
the EBI. These external Memory Controllers are capable of handling several types of external
memory and peripheral devices, such as SRAM, PROM, EPROM, EEPROM, Flash, and
SDRAM.
The EBI also supports the CompactFlash and the NAND Flash protocols via integrated circuitry
that greatly reduces the requirements for external components. Furthermore, the EBI handles
data transfers with up to six external devices, each assigned to six address spaces defined by
the embedded Memory Controller. Data transfers are performed through a 16-bit or 32-bit data
bus, an address bus of up to 26 bits, up to eight chip select lines (NCS[7:0]) and several control
pins that are generally multiplexed between the different external Memory Controllers.
