PCN Details
Description of Change:
Silicon Laboratories is pleased to announce the successful qualification of a second assembly site,
ASE Chung Li, Taiwan (ASECL), for EM357 and EM351 products. Product assembled at ASECL will
have a different marking from the product assembled at the original assembly site, Stats Chippac
Malaysia (SCM). Please see Appendix A for details of the marking differences.
There is a slight difference in the dimensions of the package from ASECL, however packages from
both assembly sites fall within the JEDEC specification for the 7x7 QFN (JEDEC ref: MO-220). See
Appendix C for details. The new dimensions will be reflected in revision 1.3 of the datasheet.
Reason for Change:
The new assembly location will provide additional capacity.
Impact on Form, Fit, Function, Quality, Reliability:
There is no impact to form, fit, function, quality or reliability of the product. The marking layout
change as described in Appendix A.
