18. Rapid Programming Algorithm
A 100 µs CE pulse width is used to program. The address is set to the first location. V
is
CC
raised to 6.5V and OE/V
is raised to 13.0V. Each address is first programmed with one
PP
100 µs CE 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 100 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
is then lowered to V
and V
to 5.0V. All bytes
PP
IL
CC
are read again and compared with the original data to determine if the device passes or fails.
