SU.HARDW.PC.CPU (2:5020/299) SU.HARDW.PC.CPU From : Tema Ershov 2:5000/7.33 Mon 16 Sep 96 08:22 Subj : Pentium FAQ [1/5] PENTIUM(r) PROCESSOR FREQUENTLY ASKED QUESTIONS URL: http://pentium.intel.com/procs/support/faqs/ppfaqx2.htm : 11--96 ------------------------------------------------------------ Q9: What do the markings on the top and bottom of my processor mean? The family of the processor is always there on top, along with the product code and frequency. For example, A80502-90 means a 90 Mhz version of the Pentium processor, model 2.

All bottomside information is laser mark. - QZZZZ = Sample Specification number. - DDDD = Serialization code. - YYY = iCOMPindex: 75MHz -- 610 90MHz -- 735 100MHz -- 815 120MHz -- 1000 133MHz -- 1110 150MHz -- 1176 166MHz -- 1308 - TT = TCP Package, A = SPGA Package - The bottom markings on the C and cB1-step production units will replace the existing bottom marking on C-step parts effective 7/95. - UU = 75 for 75-MHz Pentium Processor and PP for all other speeds. - K = V for VRE voltage range S for standard voltage range L = M for min valid MD timings S for min valid standard timings M = U is not tested for DP, is tested for UP and MP S is tested for DP, UP and MP. Three-digit numbers following SX/SK/SU/SY/SZ are known as the s-spec numbers, and identify any specific characteristics that the part has, including the stepping, or version number. S-spec numbers are always printed on top of the package and are also on the bottom for newer versions of the Pentium processor. These SX numbers have nothing to do with previous products that we've had such as the Intel486 SX processor. (M)(C) '92 '93 or (M)(C) '92 '95 are printed on the top and/or bottom. These dates give copyright information. They are not related to the date of manufacture of any product. ------------------------------------------------------------
