The device is organized as 32K words by. I believe the 29Cxxx series is now mostly flash memory. Digi-Key appears to have several thousand of the 32Kx8 AT28C EEPROM’s, which.

I find epro, hands-on work, including the debugging, to really get this information across to all levels of students. Instead, describe your situation and the specific problem you’re trying to solve. Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available at www.

There are still a few parallel flash chips available in DIP, e.

The users who voted to close gave this specific reason: I’ve been using 277c256 pin DIP package. There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

Ellen Spertus 2 9 The goal of my course, eeprom is the introductory and only architecture course at a liberal arts college, is for students to understand all the way down to the gate level how computers work, not 27c265 directly prepare them for industry. Perhaps the limited available time could be used more productively with modern hardware. It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match.


I also don’t care about speed.

I don’t have experience with FPGAs. John Miles 3 5. Can you tell me anything about it?

The instructions are read by a low-speed TTL computer they build. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of 27c2566. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so.

This question appears to be off-topic. JohnMiles, could you elaborate? You didn’t say which package you are using, I assuming it is a pin DIP. They tend to be higher capacity than eeprom devices, so more address lines to tie but otherwise equivalent to eeprom for your purposes. Robustness to student wiring mistakes would be great.

However, it struck me that you must be spending a lot of time getting them to the point where they understand what they’re hooking up, and why. I like the Nexys2, personally, and the books by Haskell eprrom Hanna look pretty good for bringing newbies up to speed.


Could you let me know why you think a FPGA approach would be better and point me to any educational material? I don’t 2c7256 you’re doing your students any favors by getting them to build stuff out of series TTL in this day and age. You could also try Jameco.

I hope to inspire some to grad school. I’d be happy with as few as 8 address bits we use two LSs for the PCalthough I doubt anyone makes something that small. I’ve never used the 28C family. I believe the 29Cxxx series is now mostly flash memory. It doesn’t need to be pin-compatible, although that would be nice.

Would the 28C family be a good place to look? One more comment in the form of an actual answer: It is a little cheaper in price, and also in stock. Home Questions Tags Users Unanswered. Not an ‘answer’ per se, just an opinion:
