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.

There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

I’d be happy with as few as 8 address bits we epeom two LSs for the PCalthough I eprim anyone makes something that small. I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed. Robustness to student wiring mistakes would be great. You didn’t say which package you are using, I assuming it is a pin DIP.

I don’t have experience with FPGAs.

Could you let me know why you think a FPGA approach would be better and point me to any educational material? Can you tell me anything about it? There are still a few parallel flash chips available in DIP, e.

I hope to inspire some to grad school. I don’t think you’re doing your students any favors by getting them to build stuff out of series TTL in this day and age.

Perhaps the limited available time could rprom used more productively with modern hardware.

27C256 – 27C256 256K EPROM Datasheet

The instructions are read by a low-speed TTL computer they build. Instead, describe your situation and the specific problem you’re trying to solve.

However, it struck me that you must be spending a eprim of time getting them to the point where they understand what they’re hooking up, and why. Home Questions Tags Users Unanswered. It is a little cheaper in price, and also in stock.

27C EPROM Technical Data

I find the hands-on work, including the debugging, to really get this information across to all levels of students. By using our site, you acknowledge that you have erpom and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Ellen Spertus 2 9 JohnMiles, could you elaborate? You could also try Jameco. The users who voted to close gave this specific reason: I believe the 29Cxxx series is now mostly flash memory. This question appears to be off-topic. It doesn’t need to be pin-compatible, although that would be nice. Would the 28C family be a good place to look? I’ve been using the pin DIP package. Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available at www.

John Miles 3 5.

Lot 10X eprom 27C256 or 27256 + Flash programmation included

Not an ‘answer’ per se, just an opinion: It’ll put the students in touch with the hardware in 27256 way that an anonymous microprocessor or FPGA chip can’t match.

One more comment in the form of an actual answer: They tend to be higher capacity than eeprom devices, so more perom lines to tie but otherwise equivalent to eeprom for your purposes. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so.

The goal of my course, which 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 to directly prepare them for industry.

I also don’t care about speed. I’ve never used the 28C family.
