18. Rapid Programming Algorithm
0311I–EPROM–12/07
A 50 µs CE pulse width is used to program. The address is set to the first location. V
raised to 6.5V and V
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 50 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
are read again and compared with the original data to determine if the device passes or fails.
PP
is raised to 13.0V. Each address is first programmed with one 50 µs CE
PP
is then lowered to 5.0V and V
