Regarding the 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
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.
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)
