Notes: 1. Electrical specifications for these speeds are defined by Standard Microcircuit Drawing 5962-88525.
2. SMD specifies Software Data Protection feature for device type, although Atmel product supplied to every device type in the
SMD is 100% tested for this feature.
3. Where two DESC numbers apply to the Atmel ordering code apply SL815 to receive parts with the noted DESC number dual
marked along with Atmel part number.
