AC Timing Characteristics – 3.3V Operation
Notes:
1. TTL buffer delays are measured from a V
IH
of 1.5V at the pad to the internal V
IH
at A. The input buffer load is constant.
2. CMOS buffer delays are measured from a V
IH
of 1/2 V
CC
at the apd to the internal V
IH
at A. The input buffer load is constant.
3. Buffer delay is to a pad voltage of 1.5V with one output switching.
4. Max specifications are the average of mas t
PDLH
and t
PDHL
.
5. Parameter based on characterization and simulation; not tested in production
6. Exact power calculation is available in an Atmel application note.
7. Load Definition: 1 = Load of one A or B input; 2 = Load of one L input; 3 = Constant Load; 4 = Load of 28 Clock Columns; 5
= Load of 28 Reset Columns; 6 = Tester Load of 50 pF.
Delays are based on fixed load. Loads for each type of device are described in the notes. Delays are in nanoseconds.
