21. External Bus Interface (EBI)
21.1
6249I–ATARM–3-Oct-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, 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 EBI0 also supports the CompactFlash and the NAND Flash protocols via integrated circuitry
that greatly reduces the requirements for external components. Furthermore, the EBI0 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 six chip select lines (NCS[5:0]) and several control
pins that are generally multiplexed between the different external Memory Controllers.
The EBI1 also supports the NAND Flash protocols via integrated circuitry that greatly reduces
the requirements for external components. Furthermore, the EBI1 handles data transfers with up
to three external devices, each assigned to three 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 23 bits, up to three chip select lines (NCS[2:0]) and several control pins that are
generally multiplexed between the different external Memory Controllers.
