ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. 25°C, 12 V V
PP
.
2. Maximum time specified is lower than worst case. Worst case is derived from the Flasherase/Flashrite pulse count
(Flasherase = 1000 max and Flashrite = 25 max). Typical worst case for program and erase is significantly less than the actual
device limit.
