You can fit an SDRAM DIMM to the core module as an option. The following type of DIMM is supported:
JEDEC r9 compliant
168 pin PL100.
The design of the core module imposes limitations on the use of a DIMM. These are:
the supplied PLD images do not provide a controller for the optional SDRAM DIMM you must implement your own
the SSRAM and optional SDRAM DIMM share many of the same interface signals and cannot both be used at the same time
the supplied CP and IM-PD1 images use the on-board SSRAM to store a display frame buffer and this precludes the option of fitting an SDRAM DIMM, see SSRAM and SDRAM DIMM interface signals.
