Table 31. Reset and Power-up AC Characteristics

2. Sampled only, not 100% tested.

3. It is important to assert RP in order to allow proper CPU initialization during Power-up or System reset.

Table 32. Program, Erase Times and Program, Erase Endurance Cycles

Note: 1. Max values refer to the maximum time allowed by the internal algorithm before error bit is set. Worst case conditions program or

erase should perform significantly better.

2. Excludes the time needed to execute the sequence for program instruction.
