External Bus Interface (EBI)
SAM9M10
Description
Embedded Characteristics
External Bus Interface
Static Memory Controller
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, DDR, SDRAM and ECC Controllers are all featured external Memory Con-
trollers 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,
DDR2 and SDRAM. The EBI operates with 1.8V or 3.3V Power Supply (VDDIOM1).
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 six chip select lines (NCS[5:0]) and several control
pins that are generally multiplexed between the different external Memory Controllers.
The SAM9M10 features an External Bus Interface to interface to a wide range of external mem-
ories and to any parallel peripheral.
• Integrates Three External Memory Controllers:
• Additional logic for NAND Flash and CompactFlash
