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

What’s a good EEPROM replacement for a 27C/29C? – Electrical Engineering Stack Exchange
In future there would be a change from 5V technology down to 3. The time now is Blood oxygen meters, Part 1: Sign up using Facebook.
I find the hands-on work, including the debugging, to really get this information across to all levels of students. Robustness to student wiring mistakes would 27cc256 great.
There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects. Potentiometer with Microcontroller 3.
Just as a follow up after some experimenting and circuit tracing, if you limit the scope to nrom rev4 prg 27c265 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.
Pardon my noobness if this is basic. Chromableed Studios 7. Perhaps the limited available time could be used more productively with modern hardware. Voltage Comparator Design 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 27c2256 prepare them for industry. It is a little cheaper in price, and also in stock.
Loved the blue wire reference from ancient times!

It’ll put the students in touch with the hardware in a way that an anonymous microprocessor 227c256 FPGA chip can’t match.
Home Questions Tags Users Unanswered. Ellen Spertus 2 9 Circuit suggestion for an current limited power supply application 6. When you place the ’28 in circuit you must: FvM 15KlausST 8barry 8ads-ee 7betwixt 6. 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. I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed.
What is a replacement for 27C Eprom? Comparing them side by side you can see the differences: The users who voted to close gave this specific reason: 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.
Dual-channel DMM puts two 7. This 27v256 appears to be off-topic. May I ask is there significance to the blue color of the wire?
Specifically, it should be reasonably priced, reliable, easily available and likely to remain so. Fuse Amperage Determination Circuit Would the 28C family be a good place to look? These low-power devices will be cheaper in future.
