Help with chip selection

Started by ankur_tandon_19 July 18, 2005
I am looking for a chip which will have the following specs:
- Fast Instruction speed more than 40,000 instruction/sec approx.
- Good amount of RAM and EEPROM
- Networking possible
- Built in A-to-D
- More than two Serial-Ports

Pleas let me know, if somebody has any idea about it. If someone knows
how to build one using BX-24 that would work too.

Thanks,
Ankur

Your requirements apart from the 2 serial ports are very vague. For example:
- Fast instruction speed: different processors even with the same
instruction rate can differ wildly in performance
- Good amount means how much? 4K? 4M? 4G?
- Networking means what? RS485? TCP/IP? Web Services?
- Built in A to D means what resolution (8, 10, 12 or larger) and how
many samples per second?

There are a vast variety of chips and platforms that might meet your
requirement. It would be better if you described what you are trying to
do. Given that this is a BasicX group we are of course going to
recommend that first and if not that, then Atmel AVRs have a lot going
for them. But this is all speculation until we get more specifics from you.

I think it really depends on the kind of networking you want to do.
You can do all that and more by using a BX-35 and a BX-01 or two
linked together.

The BX-01 supports 128k of ram in one mode and 64k of network nodes
in another, but the two are mutually exclusive in one chip. Both the
BX-24 and BX-35 have on-board A-toD, but it is 10bit resolution. You
could add an I2C A-to-D converter to any of the above and get better
resolution.

You can also add I2C ram to any of the above, or IC2 i/o that is
serial or parrallel.

In sum, it is really necessary to understand your task in order to
reduce the cost and maximize the systems performance.

Just wanting something in one package doesn't make it happen, but
with the I2C technology you can usually select a processor and the
fewest possible additions to optimize.

If Basic programing is part of the issue, they take a good look at
BasicX and see if that is your optimal programming choice to go with
it all.
