AT40K/AT40KLV Series FPGA
0896C–FPGA–04/02
All input IO characteristics measured from a VIH of 50% at the pad (CMOS threshold) to the internal VIH of 50% of VCC.All
output IO characteristics are measured as the average of tPDLH and tPDHL to the pad VIH of 50% of VCC.
AC Timing Characteristics – 5V Operation AT40K
Delays are based on fixed loads and are described in the notes.
Maximum times based on worst case: VCC = 4.75V, temperature = 70°C
Minimum times based on best case: VCC = 5.25V, temperature = 0°C
Maximum delays are the average of tPDLH and tPDHL.
All input IO characteristics measured from a V
IH of 50% of VDD at the pad (CMOS threshold) to the internal VIH of 50%
of V
CC. All output IO characteristics are measured as the average of tPDLH and tPDHL to the pad VIH of 50% of VCC.
