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.

Can you tell me anything about it? Robustness to student wiring mistakes would be great. Ellen Spertus 2 9 It’ll put the students in touch with the hardware in a way epro an anonymous microprocessor or FPGA chip can’t match. 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. Perhaps the limited available time could be used more productively with modern hardware.
I find the hands-on work, including the debugging, to really get this information across to all levels of students. I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed.

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. Instead, describe your situation and the specific problem you’re trying to solve.
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. There are still a few parallel flash chips available in DIP, e. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so. You could also try Jameco. JohnMiles, could you elaborate?
It is a little cheaper in price, and also in stock. John Miles 3 5. I believe the 29Cxxx series is now mostly flash memory. 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? It doesn’t need to be pin-compatible, although that would be nice.

I’ve been using the pin DIP package. The instructions are read by a low-speed TTL computer they build. Would the 28C family be a good place to look? 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.
There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

The users who voted to close gave this specific reason: I also don’t care about speed. You didn’t say which package you are using, I assuming it is a pin DIP. Home Questions Tags Users Unanswered.
