512 megabit synchronous dram dpsd32mx16wy5 description: the lp-stack ? series is a family of interchangeable memory modules. the 256 megabit sdram is a member of this family which utilizes the new and innovative space saving tsop stacking technology. the modules are constructed with 16 meg x 16 sdrams. this 256 megabit based lp-stack ? module, the dpsd32mx16wy5 has been designed to fit in the same footprint as the 16 meg x 16 sdram tsop monolithic and 256 megabit sdram based family of lp-stack ? modules. this allows the memory board designer to upgrade the memory in their products without redesigning the memory board, thus saving time and money. features: ? configuration available: 32 meg x 16 bit (with two chip selects) ? clock frequency: 66 [1] ,83 [1] , 100, 125 [2] , 133 [2] mhz (max.) ? pc100 and pc133 compatible ? 3.3v supply ? lvttl compatible i/o ? four bank operation ? programmable burst type, burst length, and cas latency ? 8,192 cycles / 64 ms ? auto and self refresh ? package: tsop leadless stack notes: [1] available in industrial temperature ranges only.
