Memory Module Specification KVR133X64C3/256 256MB 32M x 64-Bit PC133 CL3 168-Pin DIMM Module DESCRIPTION: This document describes ValueRAM's 32M x 64-bit (256MB) CL3 SDRAM (Synchronous DRAM) PC133 DIMM module. The components on this module include eight 32M x 8-bit (8M x 8-bit x 4 Bank) PC133 SDRAM 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. = 7.5ns (CAS Latency = 3) / max. = 1000ns 65ns max. = 5.4ns (CAS Latency = 3) +3.3V (+/- .3V) 2.376 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 1.375" (34.92mm). 5.250 (133.350) R 0.079 (R 2.000) 0.157 0.004 (4.000 0.100) 0.350 (8.890) B A .450 (11.430) C 0.250 (6.350) 0.250 (6.350) 1.450 (36.830) 2.150 (54.61) 0.100 Min (2.540 Min) .118DIA 0.004 (3.000DIA 0.100) 0.700 (17.780) 0.118 (3.000) 1.150 (29.210) 0.089 (2.26) 5.014 (127.350) 0.118 (3.000) 4.550 (115.57) 0.100 Min 0.250 (6.350) 0.250 (6.350) 0.123 0.005 (3.125 0.125) 0.079 0.004 (2.000 0.100) Detail A (2.540 Min) Units : Inches (Millimeters) 0.039 0.002 (1.000 0.050) 0.123 0.005 (3.125 0.125) 0.079 0.004 (2.000 0.100) Detail B 0.008 0.006 (0.200 0.150) 0.050 (1.270) Detail C Figure 1: KVR133X64C3/256 168-Pin SDRAM Module Document No. VALUERAM0017-001.C00 01/28/03
