18. 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 verification/reprogramming loop is executed for each address.
In the event a byte fails to pass verification, up to 10 successive 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 com-
pared with the original data to determine if the device passes or fails.
