Buy EPROM K-Bit 32K x 8 ns Pin DIP. 27C 27C 27C 27C 27C M27CBF1. M27CBF1. The Microchip Technology Inc. 27C is a CMOS K bit electrically Programmable Read Only Memory (EPROM). 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.

The instructions are read by a low-speed TTL computer they build. It doesn’t need to be pin-compatible, although that would be nice.

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 27c2556 computers work, not to directly prepare them for industry.

I’d be happy with as few as 8 address bits we use two Epprom for the PCalthough I doubt anyone makes something that small. Could you let me know why you think a FPGA approach would be better and point me to any educational material? There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

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

Would the 28C family be a good place to look? Can you tell me anything about it?

You could also try Jameco. I find the hands-on work, including the debugging, to really get this information across to all levels of students. Broke into two comments e;rom the edit function doesn’t seem to work Have you checked out some of the boards available at www.

John Miles 3 5. It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match.

Specifically, it should be reasonably priced, reliable, easily available and likely to remain so. The users who voted to close gave this specific reason: There are still a few parallel flash chips available in DIP, e. JohnMiles, could you elaborate?

Robustness to student wiring mistakes would be great. Ellen Spertus 2 9 I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed. It is a little cheaper in price, and also in stock. Not an ‘answer’ per se, just an opinion: I don’t have experience with FPGAs. I’ve never used the epprom family. Instead, describe your situation and the specific problem you’re trying to solve. You didn’t say which package you are using, I assuming it is a pin DIP.

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 eporm.

What’s a good EEPROM replacement for a 27C/29C? – Electrical Engineering Stack Exchange

I’ve been using the pin DIP package. However, it 27f256 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 also don’t care about speed. I hope to inspire some to grad school. I believe the 29Cxxx series is now mostly flash memory. They tend to be higher capacity than eeprom devices, so more address lines to tie but otherwise equivalent to eeprom for your purposes.
