2402211513 End of Life for QSOP package in EFM8BB1/2/3, EFM8LB1, EFM8SB1, EFM8UB1

PublishTime：2024-02-23

■Description of Change
●Silicon Labs announces an End of Life (EOL) and Last Time Buy (LTB) for QSOP package in EFM8BB1/2/3, EFM8LB1, EFM8SB1 and EFM8UB1 MCUs.
●Existing customers may place LTB orders per the key dates above and guidelines listed in this EOL form.
●All customer orders placed after the EOL Issue Date will be Non-Cancellable and Non-Returnable (NCNR). These orders will need to have a Customer Requested Delivery Date (CRD) before the EOL Effective Date. As of this EOL Issue Date, Silicon Labs will no longer accept customer orders with a CRD beyond the EOL Effective Date.
●Note: Silicon Labs will accept customer orders that are received prior to the Last Order Date shown above, but does not guarantee that it will be able to fill all or part of any orders due to limited availability, manufacturing issues or other reasons beyond Silicon Labs’ reasonable control. Estimated delivery dates beyond normal lead time should not be considered as a firm acceptance or a guarantee of supply at any time.
●If you have questions about this EOL, please contact your Silicon Labs sales representative.
■Reason for Change
●The supplier that provides the QSOP packaging used in these product families has announced an End of Life (EOL) of the QSOP package. No alternate supplier is available for this package type. This impacts Silicon Labs ability to manufacture the QSOP packaged devices.
●New datasheet revisions with updated ordering guide information will be announced separately.
