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.
