Rapid
Programming Algorithm
A 50 μs ALE pulse width is used to program. The address
is set to the first location. V
CC
is raised to 6.5V and OE/V
PP
is raised to 13.0V. Each address is first programmed with
one 50 μs ALE pulse without verification. Then a verifica-
tion/reprogramming loop is executed for each address. In
the event a byte fails to pass verification, up to 10 succes-
sive 50 μs pulses are applied with a verification after each
pulse. If the byte fails to verify after 10 pulses have been
applied, the part is considered failed. After the byte verifies
properly, the next address is selected until all have been
checked. OE/V
PP
is then lowered to V
IH
and V
CC
to 5.0V. All
bytes are read again and compared with the original data to
determine if the device passes or fails.
