description: the m-densus series is a family of interchangeable memory modules. the 128 megabit sdram is a member of this family which utilizes the new and innovative space saving tsop stacking technology. the module s are constructed with 4 meg x 16 sdrams. this 64 megabit based m-densus module, the dpsd8mx16ry5 has been designed to fit in the same footprint as the 4 meg x 16 sdram tsop monolithic and 64 megabit sdram based family of m-densus 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: 8 meg x 16 bit (with two chip selects) clock frequency: 66 [1] , 83 [1] , 100, 125 [2] , 133 [2] mhz (max.) pc100 and pc133 compatable 3.3v supply lvttl compatible i/o four bank operation programmable burst type, burst length, and cas latency 4096 cycles / 64 ms auto and self refresh package: tsop leadless stack notes: [1] available in military and industrial temperature ranges only.
