There is no Application jou can just build out of a 555 nor there is one

I'm thinkering to build an small Epromer for just one single sort
of Eproms (Am27C291/CY7C291..) and I'm desingning in a ?A723 currently.
What about his chip? It is old like stoneage and still in production..
Unfortunately I'm unable to emulate it's functionality with the Amtega32
that will be go in that promer (No, Im not going to build an buck converter
out of an Atmega Timer), but for sure I'm generating the program
pulse length not with a 555...

Well maybe (though no guarantee there), but the
555 would likely have the
same sort of lifetime as a microcontroller - arguably poorer.
That is 30 seconds. Wait, I guess we are not discussing marketing.
I would go with the 555 timer, the Arduino could be running near its
max clock freq.
