Memory Module Specification KVR100X72C2L/256 256MB PC100 CL2 168-Pin ECC Low Profile SDRAM DIMM Module DESCRIPTION: This document describes ValueRAM's 32M x 72-bit (256MB), CAS Latency 2 (CL2) SDRAM (Synchronous DRAM) PC100 ECC memory module. The components on this module include eighteen 16M x 8-bit (4M x 4-Bit x 4 bank) low profile PC100 CL2 SDRAM components in TSOP packages. This 168-pin DIMM uses gold contact fingers and requires +3.3V. The electrical and mechanical specifications are as follows: FEATURES: CLK Cycle Time (tCC) Row Cycle Time (tRC) CLK to Output (tSAC) Single Power Supply of Power UL Rating min. = 10ns (CAS Latency = 2) / max. = 1000ns 70ns max. = 6ns (CAS Latency = 2) +3.3V (+/- .3V) 4.728 W (operating) 94 V - 0 Note: The module defined in this data sheet is one of several configurations available under this part number. While all configurations are compatible, the DRAM combination and/or the module height may vary from what is described here. However, in no configuration will the module height exceed 1.2" (30.48mm). 5.250 (133.350) R 0.079 (R 2.000) 0.175 (4.45) 0.157 ± 0.004 (4.000 ± 0.100 ) 0.700 (17.780) 0.118 (3.000) B A .118DIA ± .004 (3.000DIA ± .100) 0.250 (6.350) 0.250 (6.350) 0.350 (8.890) .450 (11.430) C 1.450 (36.830) Units : Inches (millimeters) 0.100Min (2.540Min) 1.150 (29.210) 0.387 ± 0.062 (9.84 ± 1.59) 0.089 (2.26) 5.014 (127.350) 0.118 (3.000) 2.150 (54.61) 4.550 (115.57) 0.100 Min 0.250 (6.350 ) 0.250 (6.350 ) 0.123 ± .005 (3.125 ± .125) 0.079 ± .004 (2.000 ± .100) Detail A (2.540 Min) Tolerances : ± .005(.13) unless otherwise specified 0.039 ± .002 (1.000 ± .050) 0.123 ± .005 (3.125 ± .125) 0.079 ± .004 (2.000 ± .100) Detail B 0.010Max (0.250 Max) 0.050 (1.270 ) Detail C Figure 1: KVR100X72C2L/256 168-Pin SDRAM Module Document No. VALUERAM0225-001.B00 02/27/02
