Rapid Programming Algorithm

A 100

µs PGM pulse width is used to program. The

V

with one 100

µs PGM 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. V

5.0V. All bytes are read again and compared with the origi-

nal data to determine if the device passes or fails.
