Part and Inventory Search. I wish the core was my design, but at least I have already made some modifications and I will do more, so datasheeet at the end I will take some credit for this as well: Hierarchical block is unconnected 3. Thanks again for you very informative help!

Any thoughts of a suitable eprom type? Students interested in digital electronics, usually work with prepackaged microcontrollers writing just software in C I am younger, but I understand why you are absolutely right. If you are trying to work around not being able to source them, you are welcome to the ones I have here. All the unused address lines should be tied low or to ground and it should then work like an 8-bit 64 address memory.

The data is obvious, D0-D7 in both eproms. Similar Threads Substituting hard drive or other memory for SD card 8. Synthesized tuning, Part 2: I’ve just cleared out a lot of cobwebs and made several spiders homeless. Distorted Sine output from Transformer 8. I doubt I will ever need them, most of my work is in microcontrollers these days and most of them have more memory than a on board already! Based on your experience, what do you think about it?

The top clock according to the datasheet can go up to 20MHz and It would be interesting to test how the computer will behave in higher frequencies, since I have managed to get 54F series chips for the circuit.


You might be able to get nS from a diode array if you keep the current fairly high but that sacrifices power and logic thresholds. How should I connect the 57c45? Do you have a suitable programmer for the 57C45 before going further? I attach you a screenshot of the circuit that uses the 27c Hello, I would like to replace a 27c16 eprom in a digital circuit with a 57c45 one. Dataaheet I wish to 27d16 the project very educational, it educated me in understating many things of how computers actually work!

27C16 – 27C16 16K 150ns CMOS EPROM

Things are moving fast and we are trying to catch. Even universities even in UK, where Ddatasheet had my degree have moved to a higher level of things because they must cope with the new technology fast. I started working with logic circuits in the mid s and most ‘computers’ of that time used the kind of technology you datasueet working with.

The actual micro-instruction sequencing is timed by the RC clock in the top left corner of the schematic and it’s speed is very low.

The time now is There are only the basic digital electronics lessons who teach students about primitive stuff like flip-flops and gates etc.

How to make a digital watch with IC datasneet, not with micro? In the instruction sequencer the outputs are always enabled so it may give a slightly faster than 45nS response.

27C16 (National Semiconductor) – 16,bit ( X 8) Uv Erasable Cmos Prom Military Qualified

This is a bit out datashret topic but how should I connect a 27C to the circuit? The problem is not sourcing the eproms but speed as I mentioned. Substituting 27c16 with 57c45, how to?


dstasheet Of course I have thought of this issue for the other chips in the circuit as well, the page is not complete, so do not judge from the schematics Thanks Brian i will follow your suggestions and design the PCB that accordingly. That does not apply only in electronics. You have almost re-invented the Intel processor! That is true ttl but I think the speed can never go higher than a ns eprom, even if using F series chips for the decoder. What is the function of TR1 in this circuit 3.

Input port and input output port declaration in top module 2. How can the power consumption for computing be reduced for energy harvesting? You might be able to use PAL devices but again these need a different programming technique.

Heat sinks, Part 2: AF modulator in Transmitter what is the A? Turn on power triac – proposed circuit analysis 0. Equating complex number interms of the other 6.

Losses in inductor of a 27c1 converter 9. In principle, yes you can use a bit EPROM but old style ones are difficult to source and are normally in pin DIP packages datasheett the layout would be significantly different. CMOS Technology file 1. There are even fewer of these students that design their own processors as parts of their final year projects and when the final open-day presentation comes, they take the risk of being asked “why didn’t you do that on a modern fpga?

For your convenience I also attach the datasheets.
