As already said the 9916 stands for "1999, week 16"

The other numbers are about the batch and process line. Not really much use to us.

  • MCU device date codes
    Device markings indicate the week of manufacture and the mask set used. The date is coded as four numerical
    digits where the first two digits indicate the year and the last two digits indicate the work week. For instance, the
    date code "0301" indicates the first week of the year 2003.
  • MCU device part number prefixes
    Some MCU samples and devices are marked with an SC, PC, or XC prefix. An SC prefix denotes special/custom
    device. A PC prefix indicates a prototype device which has undergone basic testing only. An XC prefix denotes that
    the device is tested but is not fully characterized or qualified over the full range of normal manufacturing process
    variations. After full characterization and qualification, devices will be marked with the MC or SC prefix.
