preliminary 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 8 meg x 8 sdrams. this 64 megabit based m-densus module, the dpsd16mx8rky5 has been designed to fit in the same footprint as the 8 meg x 8 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: 16 meg x 8 (2 banks of 2m x 4 x 8 bits) 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 pin-out diagram functional block diagram 16mx8, 7.5 - 15ns, p12, m-densus 30a227-00 b this document contains information on a product presently under development at dense-pac microsystems, inc. dense-pac reserves the right to change products or specifications herein without prior notice. pin names a0 - a11 row address: a0 - a11 column address: a0 - a8 ba0, ba1 bank select address dq0 - dq7 data in / data out cas column address strobes ras row address enables we data write enable dqm data input/output mask cke clock enable clk system clock cs 0- cs 1 chip selects v cc /v ss power supply/ground v ccq /v ssq data output power/ground n.c. no connect 128 megabit synchronous dram dpsd16mx8rky5 m-densus high density memory device notes: [1] available in military and industrial temperature ranges only.
