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 hope to inspire some to grad school. There are still a few parallel flash chips available in DIP, e. Instead, describe your situation and the specific problem you’re trying to solve.

The instructions are read by a low-speed TTL computer they build. Perhaps the limited available time could be used more productively with modern hardware.

Could you let me know why you think a FPGA approach would be better and point me to any educational material? Specifically, it should be reasonably priced, reliable, easily available and likely to remain so.

I’ve been using the pin DIP package. This question appears to be off-topic.


I also don’t care about speed. It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match. The goal of my course, which eptom 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.

Ellen Spertus 2 9 I’ve never used the 28C family. Home Questions Tags Users Unanswered. There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

John Miles 3 5. The users who voted to close gave this specific reason: It is a little cheaper in price, and also in stock. It doesn’t need to be pin-compatible, although that would be nice. However, it struck me that you must be 27c25 a lot of time getting them to the point where they understand what they’re hooking up, and why.

I don’t have experience with FPGAs. Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the eproj available at www.

JohnMiles, could you elaborate?

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 like the Nexys2, personally, and the books by Haskell and Hanna epfom pretty good for bringing newbies up to speed.

I believe the 29Cxxx series is now mostly flash memory. You didn’t say which package you are using, I assuming it is a pin DIP. I find the hands-on work, including the debugging, to really get this information across to all levels of students. One more comment in the form of an actual answer: They tend to be higher capacity than eeprom devices, so more address lines to tie but otherwise equivalent to eeprom for your purposes.

Can you tell me anything about it? Not an ‘answer’ per se, just an opinion: You could also try Jameco. Would the 28C family be a good place to look?

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. Robustness to student wiring mistakes would be great.
