Replace MX29LV640 by W25Q64JV is it possible ?

[Kayumba]

Hello guys.
Will I be possible to remplace MX29LV640 (3v 64Mbit) 48 pins TSOP by W25Q64JV (3v 64Mbit) 8-pin SOIC ?
By using some converters or something like that?

It depends how you're actually going to use it - a serial EEPROM/Flash ROM will work great for storing saved games (case in point: Playstation memory cards worked that way), but it's going to be useless for directly executing code (unless you can put something else in front of it which can send it the address and retrieve the data within a single CPU clock cycle).

Some more information would be useful - where exactly are you planning on using this?

Hi,
Thank you for answer.
Well, cause of the price per unit I'am looking for to replace my actual Flash for SNES games with something chipper.

Going from parallel to serial access is going to be a royal PITA, you'd need an interface IC that is able to take the parallel buses and strobe that into the necessary serial pulse trains to drive the new chip. I personally wouldn't put that amount of effort into something like this, but hey it is certainly an interesting learning experience.

An adapter from parallel to serial would behave somewhat like an EverDrive: a big RAM, a boot ROM (or a means to hold the console in reset), and a means to copy data between RAM and serial flash memory.
