Doing the same trick on 29f flash memory does not work. Like lidnariq said, an inverter is about as simple as it gets.

29F Technical Data

Display posts from previous: Page 1 of 1. Users browsing this forum: In reality, with the 39SF I’ve found that I can actually just wait a fixed amount of time instead of polling. By the time the 29t040 runs all that code, it’s supposed to be finished datasheet lists the timing. This will work, because when!

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 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. Do you have any other ideas? CE to out from address decoder -! View unanswered posts View active topics.



OE tied to GND! Previous topic Next topic.

Luckily, 29f need special 4 cycle write command to program one byte: I 29v040 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. Tue Oct 20, 5: Tue Oct 20, 4: So I have two solutions: CE to GND – tie!

OE are active in 29f flash, the memory is in unknown state. Google [Bot] and 11 guests.

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. WR as Z80 does, for example.


Admittedly, I’ve put near zero effort into optimizing my flash writing routines I’d just rather have it be ‘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!

The 2nd method is certainly clever, but I’d have to say it seems a little yucky. I’ve done the first method on like 3 different board designs, and it works fine.

W signal instead of two! Unfortunately, those are approximately your only options. 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.
