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 27C is a high-speed K UV erasable and electri- cally reprogrammable CMOS EPROM ideally suited for ap- plications where fast turnaround pattern. 27C, 27C Datasheet, 27C K EPROM Datasheet, buy 27C

You didn’t say which package you are using, I assuming it is a pin DIP. I hope to inspire some to grad school. May I ask is there significance to the blue color of the wire?
Circuit suggestion for an current limited power supply application 6. FvM 15KlausST 8barry 8ads-ee 7betwixt 6. If you need an Eprom you can choose a bigger one and connect unused address-lines to gnd.
Robustness to student wiring mistakes would be great. They are easy to find with densities of 1MBit and up. Pardon my noobness if this is basic.

The time now is You know in those situations where the terrorists always follow the standard wiring code? They tend to be higher capacity than eeprom devices, so more address lines to tie but otherwise equivalent to eeprom for your purposes.
It doesn’t need to be pin-compatible, although that would be nice. I believe the 29Cxxx series is 27c265 mostly flash memory.
It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match. Visit manufacturers’ website Many chips could be used, different voltage and package. Nope, it’s just called blue wiring because in the wirewrap days SOME companies reserved certain colors for repairs and fixes. Voltage Comparator Design Quiery regarding cadence Initial and final energy stored in a capacitor Not an ‘answer’ per se, just an opinion: I also don’t care about speed.
The users who voted to close gave this specific reason: I don’t have experience with FPGAs.

Other technologies as FLASH 29f will be more modern, but with such a small amount of memory 32kByte you will also get problems to buy them. Some can be found at EDAboard, e.
Home Questions Tags Users Unanswered. 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.
Post as a guest Name. Perhaps the limited available time could be used more productively with modern hardware. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so. A lot 2c7256 companies you could choose! You could also try Jameco. Just as a follow up after some experimenting and circuit tracing, if you limit the scope to nrom rev4 prg for example which only uses 16K of the 28c the A14 pin27 is already connected to pin 1 and 28 on the board and the 28c can be socketed without any extra wires, I guess since the highest address line wouldn’t be needed.
There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects. Comparing them side by side you 27c2556 see the differences: Instead, describe your situation and the specific problem you’re trying to solve. Part and Inventory Search.
