Read content of MR27V3202F µC

[patrick1988]

Hello,

I have an OKI Semiconductor µC "MR27V3202F" with unknown content.
Is there a easy way to read the complete content of this µC, as possible with LabView?

The elected content should be written to a new µC, "AMIC A29L320A". Is this also possible with an PXI and LabVIEW?

Thanks,

Hi Patrick,

do you talk about data sent from one µC to a different µC? Or do you want to copy the flash RAM (the "program"), so doing the work of a (kind of) EPROMmer?

The ideal solution is the direct copying from the MR27V3202F to the AMIC A29L320A.

If this solution isn't possible, it would be nice to read the data from MR27V3202F so that i have the complete content of the Memory.

Thanks,

The MR27V3202F is a 32 Mbit electrically One Time Programmable Read-Only Memory, not a uC. And your other chip is a flash flash memory. In order to read the MR27V3202F you need 20 digital address lines, and at least 8 digital lines for the data. And some lines for control. I guess it is doable indeed.

I guess a state machine simulating the read cycle of a CPU would do fine in order to read the ROM. Find some examples on digital IO using Labview example finder. Then post some code, so we can discuss it.
