Notes 1.
The recommended setting value of the step erase time is 0.2 s.
The prewrite time prior to erasure and the erase verify time (write-back time) are not included.
The recommended setting value of the write-back time is 1 ms.
Write-back is executed once by the issuance of the write-back command. Therefore, the retry count
must be the maximum value minus the number of commands issued.
The recommended setting value of the step writing time is 20
μ
s.
20
μ
s is added to the actual writing time per word. The internal verify time during and after the writing
is not included.
When writing initially to shipped products, it is counted as one rewrite for both
“
erase to write
”
and
“
write only
”
.

When the PG-FP3 is used, a time parameter required for writing/erasing by downloading
parameter files is automatically set. Do not change the settings unless otherwise specified.
