Programming Flowchart (High-speed Programming Mode)
the VPP pin when Vcc = 6.25 V. After the address and input data are stable, the data is
programmed by applying a single 0.1ms program pulse to the
data is verified. If incorrect, another 0.1ms program pulse is applied. This process should be
repeated (up to 25 times) until the program operates correctly. After that, change the address
and input data, and program as before. When programming has been completed, the data in all
addresses should be verified with Vcc = Vpp = 5 V.
The high-speed programming mode is achieved by applying the program voltage (+12.75 V) to
