Memory Module Specification KVR133X72C3L/256 133MHz SDRAM 168-Pin ECC PC133 DIMM Memory Module DESCRIPTION: This document describes ValueRAM's 32M x 72-bit (256MB), CAS Latency 3 (CL3) SDRAM (Synchronous DRAM) 133MHz ECC memory module. The components on this module include nine 32M x 8-bit (8M x 8-bit x 4 Bank / PC133 components) 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) 3.860 W (operating) 94 V - 0 Units : Inches (Millimeters) 5.250 (133.350) 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) 0.096 (2.44) R 0.050+0.04 (R 1.27+0.1) R 0.079 (R 2.000) 0.125 (3.175) 1.150 (29.210) 0.375 (9.525) 0.089 (2.26) 5.014 (127.350) 0.118 (3.000) 4.550 (115.57) Tolerances : ± .005(.13) unless otherwise specified Figure 1: KVR133X72C3L/256 168-Pin SDRAM Module Part No. VALUERAM0216-001.A00 11/15/01
