21. External Bus Interface (EBI)
21.1
6462B–ATARM–6-Sep-11
Overview
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 and SDRAM 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 eight external devices, each assigned to eight 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.
