The DNMEG_SODIMM_4FLASH is a daughter card intended to add four Micron FLASH memories and a DDR2 SODIMM to any expansion slot on an FPGA board from The Dini Group. A 48-pin TSOP socket is used, allowing the FLASH memories to be programmed by an off-the-shelf FLASH programmer. The Micron MT29F64G08TAAWP is the target FLASH device, but connections are provided to allow the use of almost any FLASH chip in a 48-pin TSOP package and also ONFI 2.0 Flash Memory. The interface to all FLASH memories is easily debugged using a logic analyzer cabled to two mictor connectors. The two mictors are connected to all four of the FLASH memory address, data, clock, and control signals.


A DDR2 SODIMM socket is used. The socket is tested to xxx Mhz with a DDR2 SODIMM. Standard, off-the-shelf DDR2 memory DIMMs (PC2-5300) work nicely and we can provide these for a small charge. We have developed alternative SODIMMs that can be stuffed into these positions. Consult the factory for more details, but the list includes FLASH, SSRAM, QDR SSRAM, RLDRAM I/II, SDR SDRAM, mictors, DDR1, DDR3, and
