8-bit MCU Longevity Commitment

Silicon Labs targets a minimum 10-year life cycle for all members of its 8-bit family of microcontrollers. The 8-bit MCU family is targeted toward applications and industry segments that require stable life cycles. The 8-bit family of MCUs has been designed using the widely-available Mixed-Signal CMOS process technology.

Silicon Labs provides a minimum longevity commitment for continued availability of all its 8-bit MCU product families until clearly defined dates as set out below. If, for business, technical or other reasons beyond Silicon Labs’ reasonable control, Silicon Labs finds that it is necessary to discontinue a product, our policy is to issue an EOL notice that provides 6 months from notice to place final orders and 12 months from notice for final shipments. If it becomes necessary to transfer the production of a product to an alternate manufacturing facility or technology, Silicon Labs will notify customers using its standard PCN procedures.
