• Manufacturer: ATMEL [ATMEL Corporation]

AC Timing Characteristics – 3.3V Operation AT40KLV
Delays are based on fixed loads and are described in the notes.
Maximum times based on worst case: V
Minimum times based on best case: V
Maximum delays are the average of t
Clocks and Reset Input buffers are measured from a V
Maximum times for clock input buffers and internal drivers are measured for rising edge delays only.
