18. Rapid Programming Algorithm
A 100 µs PGM pulse width is used to program. The address is set to the first location. V
is
CC
raised to 6.5V and V
is raised to 13.0V. Each address is first programmed with one 100 µs
PP
PGM pulse without verification. Then a verification/reprogramming loop is executed for each
address. In the event a word fails to pass verification, up to 10 successive 100 µs pulses are
applied with a verification after each pulse. If the word fails to verify after 10 pulses have been
applied, the part is considered failed. After the word verifies properly, the next address is
selected until all have been checked. V
is then lowered to 5.0V and V
to 5.0V. All words are
PP
CC
read again and compared with the original data to determine if the device passes or fails.
