In principle, yes you can use a bit EPROM but old style ones are difficult to source and are normally dahasheet pin DIP packages so the layout would be significantly different. Turn on power triac – proposed circuit analysis 0.

Equating complex number interms of the other 6. PV charger battery circuit 4. Thanks Brian, this is what I am trying to make http: Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

It gives you a good understanding of what goes on inside a microprocessor and why they work. Part and Inventory Search. 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.

I see too many students these days who just assume you plug a mouse and keyboard into a box and HD graphics appear by magic. Do you have a suitable datsheet for the 57C45 before going further? Hierarchical block is unconnected 3. 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.

PNP transistor not working 2. You might be able to use PAL devices but again these need a different programming technique.

The address seems obvious too, use only A0-A5 of the 57c45 and ground the dtasheet of adress lines. People in your age, can teach how these things actually work, as you have worked with these, whereas people in my age are just in the edge or a bit too late.

However I think you are right about the glitch problem, but this is due to the eprom used and may not apply to the faster eprom, this is something I need to try. Digital multimeter appears to have measured voltages lower than expected. Similar Threads Substituting hard drive or other memory for SD card 8.

Any thoughts of a suitable eprom type? It would be much simpler to use a larger but compatible device such as, and so on but they have more pins so they won’t fit straight in to the same socket.

Choosing IC with EN signal 2. Substituting 27c16 with 57c45, how to? Synthesized tuning, Part 2: All the unused address lines should be tied low or to ground and it should then work like an 8-bit 64 address memory. Dec 242: I started working with logic circuits in the mid s and most ‘computers’ of that time used the kind of technology you are working with. That is why these forums are so important; listen, talk and learn from older ones My final idea is to completely replace the two eproms with a 1n bit diode matrix and a address decoder out of a few demux chips.

Hello, I would like to replace a 27c16 eprom in a digital circuit with a 57c45 one. For your convenience I also attach the datasheets. CMOS Technology file 1. Losses in inductor of a boost converter 9. If you are trying to work around not being able to source them, you are welcome to the ones I have here.

How do you get an MCU design to market quickly? 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?

Primarily, it has a latched output although the data sheet suggests it may be possible to bypass it. 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. This is a bit out of topic but how should I connect a 27C to the circuit? What is the function of TR1 in this circuit 3.
