Differences between LE80536LC0172M-SL89N, LE80536LC0172M-SLJ8U, and RJ80536LC0172M-SLJ95

Hello, Processors Community. This is my first post here. I hope someone can help me with a pretty nuanced question.

I am working on a product that originally used the LE80536LC0172M (/products/27603/Intel-Pentium-M-Processor-LV-738-2M-Cache-1_40-GHz-400-MHz-FSB Intel® Pentium® M Processor LV 738 (2M Cache, 1.40 GHz, 400 MHz FSB) with S-Spec SL89N. I saw there was a change in the S-Spec for this part (SL89N → SLJ8U), as well as a change in MM# (868295 → 915861) and MDDS Pkg ID (1062 → 5980). I saw this in the https://qdms.intel.com/MDDS/MDDSView.aspx?mm=915861 MDDS document for the part. It looks like this was a change to make the part RoHS-compliant. I understand I can't order MM# 868295 anymore, and that's fine. Can someone please confirm that all changes between the different MM# are explained in the MDDS document, that it's just making a RoHS-compliant version?

The RJ80536LC0172M appears to be the exact same processor as the LE80536LC0172M, except that it has a different S-Spec, MM# , and MDDS Pkg ID. The https://qdms.intel.com/MDDS/MDDSView.aspx?mm=915870 MDDS document for the "RJ" version shows that it is not RoHS-compliant because of lead solder beads and brominated flame retardants. Can someone please disclose if there are any differences between the "LE" and the "RJ" versions, besides the solder beads? One of my associates recommended replacing the LE80536LC0172M-SL89N with the RJ80536LC0172M-SLJ95, but I have to know what differences there are between the version numbers, if any.

Thanks for you help,

Matt

Hello again. I just wanted to add that I'm curious what the step code change from C0 on the old S-Spec S L89N to the code C1 on the new S-Spec S L8JU means. Can someone please disclose what changes were made to the CPU die in the step code change?

Thanks for your help,

Matt

Hello Matt,

Regarding the /products/27603/Intel-Pentium-M-Processor-LV-738-2M-Cache-1_40-GHz-400-MHz-FSB Intel® Pentium® M Processor LV 738 the only difference between these 2 version is to make it ROHS compliant.

The only difference between the "LE" and the "RJ" versions is the solder beads. The RJ is still RoHS compliant because there is an exemption for the low level of lead used (see the MDDS for SLJ95 for details, https://qdms.intel.com/MDDS/MDDSView.aspx?mm=915870 https://qdms.intel.com/MDDS/MDDSView.aspx?mm=915870

Thank you, Sylvia. That is useful information.

Can you please address the stepping code change that happened between the -SL89N version and the -SL8JU version of the LE80536LC0172M CPU? The -SL89N version has stepping code C0, and the -SL8JU version has stepping code C1. Usually, an updated stepping code means a change to the CPU die, correct? I'd like to know what changed on the die between stepping codes C0 and C1, if you can disclose that information.

Thanks,

Matt Lauer

There were no functional die changes. The only changes were to the material used in manufacturing the die to make it ROHS compliant. The details are in PCN 110467-01 http:///qdms.intel.com/dm/d.aspx/D6202EEB-ECD0-4B98-AAF1-B8E21D67B021/PCN110467-01.pdf) http:///qdms.intel.com/dm/d.aspx/D6202EEB-ECD0-4B98-AAF1-B8E21D67B021/PCN110467-01.pdf)
