How should I connect the 57c45?

Thank you very much for your kind offer Brian. Substituting 27c16 with 57c45, how to? Input port and input output port declaration in top module 2. The actual micro-instruction sequencing is timed by the RC clock in the top left ddatasheet of the schematic and it’s speed is very low. You have almost re-invented the Intel processor!

What is the function of TR1 in this circuit 3. 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. CMOS Technology file 1. How to make a digital watch with IC counter, not with micro?


I think that is the reason why. How reliable is it? I attach you a screenshot of the circuit that uses the datasueet Students 271c6 in digital electronics, usually work with prepackaged microcontrollers writing just software in C I am younger, but I understand why you are absolutely right. I think I will make the original version on the PCB and later on try modifications to accept the newer eprom, based on the pin connections you indicated.

My final idea is to completely replace the two eproms dataaheet a 1n bit diode matrix and a address decoder out of a few demux chips. I wish the core was my design, but at least I have already made some modifications and I will do more, so hopefully at the end I will take some credit for this dafasheet well: Hello, I would like to replace a 27c16 eprom in a digital circuit with a 57c45 one.

27C16 – 27C16 16K 150ns CMOS EPROM

Thanks again for you very informative help! Dec 248: Thanks Brian, this is what I am trying to make http: It gives you a good understanding of what goes on inside a microprocessor and why they work. Based on your experience, what do datashewt think about it? Any thoughts of a suitable eprom type?


Could you guess, what are these features you refer to by seeing the schematic? Those of us who understand their inner workings are rare and I fear, a dying breed!

However I think you datasheeh 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. Things are moving fast and we are trying to catch. In principle, yes you can use a bit EPROM but old style ones are difficult to source and are normally in pin DIP packages so the layout would be significantly different.

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.

How do you get an MCU design to market quickly? Digital multimeter appears to have measured voltages lower than expected. Primarily, it has a latched output although the data sheet suggests it may be possible to bypass it.
