How to program

[tkurbad]

Hi,

thanks for the design!

More a question than an issue: How do I program the flash chip once it's soldered to the board? Can I just use a regular Epromer with correct pinout and program the device like a 27C800? Or do I have to adjust voltages etc.?

Thank you in advance,
Torsten

Untested, but it's designed for read only.

I think that the flash memories need 5V for programming when epom needs 12V but I'm not sure, never read the datasheet for programming...

Thanks. I've had a glance at the datasheet and think the flash can handle up to 13V for programming, but I'll try with lower voltages first.
The reset and write enable lines might be a problem, though...

Yes, /reset and /we are on high for default and, I don't know if it will work with the dual bank...
