512 Megabit CMOS DDR SDRAM DPDD32MX16WSCY5 ADVANCED INFORMATION DESCRIPTION: PIN-OUT DIAGRAM The LP-StackTM series is a family of interchangeable memory devices. The 512 Megabit Double Data Rate Synchronous DRAM is a member of this family which utilizes the new and innovative space saving TSOP stacking technology. The devices are constructed with two 16 Meg x 16 DDR SDRAM's. The 512 Megabit LP-StackTM modules DPDD32MX16WSCY5, based on 256 Megabit devices, has been designed to fit in the same footprint as the 16 Meg x 16 DDR SDRAM TSOP monolithic. This allows for system upgrade without electrical or mechanical redesign. Providing an immediate and low cost memory solution.
