Implementation Examples
AT91SAM9G10
16-bit SDRAM
Hardware Configuration
Software Configuration
All the hardware configurations are given for illustration only. The user should refer to the mem-
ory manufacturer web site to check the device availability.
The following configuration has to be performed:
The Data Bus Width is to be programmed to 16 bits.
The SDRAM initialization sequence is described in the “SDRAM device initialisation” part of the
SDRAM controller.
• Assign the EBI CS1 to the SDRAM controller by setting the bit EBI_CS1A in the EBI Chip
• Initialize the SDRAM Controller depending on the SDRAM device and system bus frequency.
(Not used A12)
