8-bit MCU Longevity Commitment
Silicon Labs targets a minimum 10-year life cycle for all members of its C8051 family of microcontrollers. The C8051 family is targeted toward applications and industry segments that require stable life cycles. The C8051 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 C8051 product families until clearly defined dates as set out below. The longevity commitment includes the standard C8051 end-of-life notification policy (six months' notice for placement of final orders for shipment within 12 months from the notice date). 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.
