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.

I also don’t care about speed. There is also a 8Kx8 version of the perom chip with a compatible pinout unused address lines are no connects.

Ellen Spertus 2 9 John Miles 3 5. 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. 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 27c2556 how computers work, not to directly prepare them for industry.

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.


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

I’ve been using the pin DIP package. I like the Nexys2, personally, and the books by Haskell eprkm Hanna look pretty good for bringing newbies up to speed. This question appears to be off-topic.

Not an ‘answer’ per se, just an opinion: 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. JohnMiles, could you elaborate? eproj

It doesn’t need to 27cc256 pin-compatible, although that would be nice. I find the hands-on work, including the debugging, to really get this information across to all levels of students. It’ll put the students in touch with the hardware in a way epfom an anonymous microprocessor or FPGA chip can’t match.

One more comment in the form of an actual answer: Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available at www. The instructions are read by a low-speed TTL computer they build.

They tend to be higher capacity than eeprom devices, 277c256 more address lines to tie but otherwise equivalent to eeprom perom your purposes.

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

Perhaps the limited available time could be used more productively with modern hardware. The users who voted to close gave this specific reason: Can you tell me anything about it? Instead, describe your situation and the specific problem you’re trying to solve. 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 hope to inspire some to grad school. I don’t have experience with FPGAs.

I’ve never used the 28C family. Home Questions Tags Users Unanswered. It is a little cheaper in price, and also in stock.

There are still a few parallel flash chips available in DIP, e. Robustness to student wiring mistakes would be great.
