Programming Flow Chart
The programming mode is set by applying 12.5V
(programming voltage) to the VPP pin when the following
pins are set as follows,
(Vcc : 6.0V)
(RESET): “L” level) obtained by using adaptor
(CLK) : “L” level) socket.
*These conditions can be
After the address and data have been fixed, a data on
the Data Bus is programmed when the CE pin is set to
“Low” (1ms plus is required).
General programming procedure of an EPROM
programmer is as follows,
Write a data to a specified address for 1ms.
Verify the data. If the read-out data does not match
the expected data, another writing is performed until
the correct data is written (Max. 25 times).
After the correct data is written, an additional writing is
performed by using three times longer programming
pulse width (1ms x programming times), or using three
times more programming pulse number. Then, verify
the data and increment the address.
The verification for all data is done under the condition
of Vpp = Vcc = 5V after all data were written.
Figure 3.3 shows the programming flow chart.
