●Description of Change
■Silicon Labs announces an End of Life (EOL) and Last Time Buy (LTB) for Select Si4x2x 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.
●Reason for Change
■Low volume 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.
