AT40K/AT40KLV Series FPGA
0896C–FPGA–04/02
Notes:
1. CMOS buffer delays are measured from a V
IH of 1/2 VCC at the pad to the internal VIH at A. The input buffer load is constant.
2. Buffer delay is to a pad voltage of 1.5V with one output switching.
3. Parameter based on characterization and simulation; not tested in production.
4. Exact power calculation is available in Atmel FPGA Designer software.
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: VCC = 3.0V, temperature = 70°C
Minimum times based on best case: VCC = 3.6V, temperature = 0°C
