Can I Change a device parameter from 3.3V to 5V?

[Guest]

Hello,

I am attempting to use my 48XP programmer to read a mask ROM. The part that I am trying to read is a Samsung KM23C64000G-12, which is a 64Mbit (8Mx16) 5V Mask ROM. It is a very old part. However, after some digging, I have found that my mask ROM part is similar to some Dataman "compatible" flash parts today. For instance, the OKI MR27V6402G *44TS is pin compatible, but it is 3.3V only.

The Mask ROM that I need to read is 5V. Is there a way to modify the parameters for the OKI's algorithm in order to get the 48XP to produce 5V when reading?

Thanks in advance,
-Alan

Please select Utron 23C64100 which is compatible with the samsung chip.
