Admittedly, I’ve put near zero effort into optimizing my flash writing routines I’d just rather have it 29f400 ‘safe’but I’m pretty sure when I get to the polling part I’ve always ended up using some temporary RAM values.
That is becase when both!
W signal instead of two! Tue Oct 20, 4: Tue Oct 20, 6: In reality, with the 39SF I’ve found that I can actually just wait a fixed amount of time instead of polling.
WR as Z80 does, for example. I would like to connect 4Mbit flash memory 29f to famicom so that famicom would be able to erase and program it, but I encountered a problem. CS to some kind of decoder!

Do you have any other ideas? Display posts 29c040 previous: The AM29FB however, it’s been years since I used that chip, but I remember it took wildly different amounts of time for the erase to finish, and it’s probably the same for programming too.
This will work, because when! I’ve done the first method on like 3 different board designs, and it works fine. View unanswered posts View active topics.
OE are active in 29f flash, the memory is in unknown state. If you have no use for the other gates on a quad or triple gate 74HC, and wanted to get fancy, you could use a 74HC1G The 2nd method is certainly clever, but I’d have to say it seems a little yucky. Page 1 of 1. So I have two solutions: Users browsing this forum: Doing the same trick on 29f flash memory does not work. On my very first board I tried making an inverter out of a transistor and 2 resistors, but failed miserably luckily I left a space for a 74HC04 on the board in case it didn’t work, hehe.

Luckily, 29f need special 4 cycle write command to program one byte: It is currently Fri Nov 09, CE to GND – tie! Technically you can send the commands and have it work fine, but there is a bit more to it, and that’s the polling required to check if the programming is done.
By the time the NES runs all that code, it’s supposed to be finished datasheet lists the timing. Unfortunately, those are approximately your 29f0040 options.
Tue Oct 20, 5: Like lidnariq said, an inverter is about as simple as it gets.
