Some noobish questions
Some noobish questions –
I would be interested in producing an ice based chip just for fun and as a learning experience.
I'm sorry if these are pretty beginner questions, but I don't have alot of experience in electronics. I can do the soldering etc.
I'm just wondering what components I'll need. I've been looking at the schematics and I see I'll need an SX28 or SX48 right? I've been looking around and can't seem to find exactly that chip, but looking at some ice based chips I've got laying around I see that they're commonly used.
Also, I need a 50M crystal, a cap, a resistor by reset, and another resistor next to the crystal?
I'm just wondering if there is a resourse that would lay out exactly how to go about building a chip. I'm just in it for the learning...
If you know anything that I should read that would help, I would really appreciate your time!
Okay I think I've read pretty much everything I need to know.
But just one question - do I need two 74HC73?
Nope just one, its a dual flip-flop.

You may already know this, but once you build the chip, you'll need a programmer to actually put any code on it. Check out Fluffy, Fluffy 2 (both based on a PIC microcontroller so you'll need to have/obtain a PIC programmer as well; Fluffy 2 is nicer but serial-only whereas Fluffy can be built for parallel port allowing you to skip buying a MAX232). If you really want to skip using a PIC, then you might want to have a look at Ubicom's Application Note 24.
Hope this helps.
That's ****ing amazing. Thanks so much
So I've gotta build a simple programmer such as the uJDM.
Then I can build the Fluffy 2, and program the ICs for it with the uJDM programmer. (that'll be fun - making PCB! Never done that before)
Then I can programming the Scenix chip with Ice with Fluffy2, and build the circuit. I won't need to make PCB - I'm assuming that I can just use strip board.
Thanks alot for the links and info.
