Description of Change

Silicon Labs announces an End of Life (EOL) and Last Time Buy (LTB) for parts listed in Product Identification section.

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.

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. A list of Silicon Labs sales

representatives is available at www.silabs.com.
