●Description of Change
■Silicon Labs announces an End of Life (EOL) and Last Time Buy (LTB) for Si1143/44 HRM and Select Si114x Devices.
■Existing customers may place LTB orders per the key dates above and guidelines listed in this EOL form.
■All customer orders with a Customer Requested Delivery Date (CRD) between the Last Time Buy (Order) Date and the EOL Effective Date will be Non-Cancellable and Non-Returnable (NCNR). As of this EOL Date, Silicon Labs will no longer accept customer orders with a CRD beyond the EOL Effective Date.
■If you have questions about this EOL, please contact your Silicon Labs sales representative. A list of Silicon Labs sales representatives is available at website.
●Reason for Change
■Customer demand does not meet minimum manufacturing requirement.
■Ordering guides on Si1141-42-43 Datasheet v1.43 and Si1145-46-47 Datasheet v1.41 have been updated to note the End of Life part numbers.
■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.
●Impact on Form, Fit, Function, Quality, Reliability
■None
