Program and Erase operations are controlled by internal stop timers.
‘Typicals’ are not guaranteed, but based on characterization data. Data taken at 25 C, 12.0V V
Minimum byte programming time (excluding system overhead) is 16 s (10 s program + 6 s write recovery), while maximum is 400 s/
byte (16 s x 25 loops). Max chip programming time is specified lower than the worst case allowed by the programming algorithm since
most bytes program significantly faster than the worst case byte.
Excludes 00H Programming prior to Erasure.
