NEED HELP!! Mystery Flash chip MFM8516

[Retromat]

Greetings everyone,

i have a very unusual flash rom here and i think i cannot find any eeprom/flash programmer that can handle this rom.
Here is the datasheet https://pdf.searchdatasheet.com/a5b8ea50/mosaicsemi.com/MFM8516VI-15E.pdf
Its a MFM8516 and i NEED to find a way ro Read and write it, the datasheet gives exact details how it operates but what could i use to actually make this happen?
Is there any programmable flash rom reader out there? Is anywone willing maybe (I will pay but cant send the chip to you) to help me on this thing?

What is so very unusual about this chip? Address bus, data bus, /CE, /OE and /WE signals -- all the same for the past 40 years.

I know
its the way the data i written and read to it, and i can not find any software that supports this chip...

On a quick read through the datasheet, it seems to be a standard command set. Pick any supported device of the same geometry and it will likely just work.

[Retromat]

hmmmm would you be able to recommend one?

[ataradov]

It is hard to tell without knowing what your programmer supports. From a random search, something like MX29F040C might work.

MX29F040C supports some additional commands, like reading a device ID, so if the programmer tries to use it, it might fail. You will have to look for even more basic equivalent.

28C040 should at least allow you to read it, just do not try to identify the device.

thanks! that sond promising, i iwll be using a Galep5 for this but if you have any recommendation for something even better?

[Retromat]

The funyn thing is, i have a second bard with the same layouts but then the chips on them are a WMF512K8  and they seem identical. I attached the spec sheet there too as i would bet they have the same operations just different manufacturers?

[ataradov]

Yes, those devices are roughly identical. Flash is flash, it has been standardized.  There are minor differences between the devices, but overall they all are interchangeable on a basic level (provided the same or better speed grade is used).
