View Full Version : An exchange of chips...

I love Maxim ... their sample system is awesome... The one down side is most everything I could use at this time (due to the lack of ability at soldering) is DIP componets.
Recently I asked for samples of their 2 wire 16 port i/o expander, and as anticipated, they shipped 4 of them, all of which are either ssop or tssop format, too small for me to work with.· I'm willing to exchange all 4 chips for an equal amount of ports (4 chips * 16 ports = 64 ports) on what ever number of chips... all must be DIP format...· You pay shipping to me, I'll pay shipping back...

For any interested, here's the url of the chips I have in hand:· http://datasheets.maxim-ic.com/en/ds/MAX7318.pdf

Any takers?

Are you looking for a MAX7318 in DIP? They don't exist. Im not aware of any I2C port expansion chips from any manufacturer in DIP format, SOIC maybe but not DIP.

Sorry I posted this in the wrong place... and more then likely I posted the other thread in the wrong place...
Not my day...
Anyway, No, I'm not looking for the MAX7318 in DIP, I'm looking for any port expander in DIP... I just need the port count...

Paul, what about the MCP23016 - that's I2C, 28-pin DIP.

Thanks Sid for the suggestion!
I hopped on out to Microchip's site and requested samples of the chip...
With some waiting, I should have them here soon!
... I don't know what I'm going to do with the MAX's if I do get the samples from microchip...

Hehe, thanks Sid, I was waiting for someone to correct me, I almost did it myself with the MAX7300, but there was a mismatch between the product page and the datasheet on whether the part is availible in DIP.

I fear that unless the manufactures really commit to providing DIP packaging for product development and educational purposes, they are going to suddenly be gone -- like a paper soda straw.

Just gone without any comment or explanation.

I do understand that it is somewhat of a burden and certainly if you are just giving the stuff away as free samples it is more so. But I really don't see how the next generation of electronic engineers is going to have any hands-on skills and pragmatic knowledge of the physical construction of these things.

Also, the 0.1" breadboard is a creative standard. It allows us the freedom to quickly try something that is poorly understood or wildly innovative.

In other words, allow people to play with the products.

Mebbe you want to try a schmartboard ?· www.schmartboard.com (http://www.schmartboard.com)· Sooner or later everyone'll have to adopt, adapt improve; the DIPs are Blowin' in the Wind, for·The Times They are A-Changin'.· It's not about hobbyists, it's about industry; that's who the parts are made for -- we get the left-overs, over-stock, etc.· They're not developing "talent", it's not about altruism, or warm-fuzzies, that's just not their mission, man; they're knocking out widgits.

PJ,
I'd like to use the schmartboards, the biggest issue I have is trying to fingure out WHICH of the bleepin formats... ssop, tssop. soic, tsoip.. then there's the spacing...
Maybe someone could tell me what are the 'magic' number on the spec sheets that tell me which form factor it is...

Kaos Kidd, what do you put under what occupation line, i am acctully thinking of getting some samples but are not sure what to put under the occupation line

Uhm, what is your occupation? I don't think they really care that much. Well, maybe some.

I would say that, if you don't work at some huge electronics manufacturing company, then just say student, or researcher or something. Whatever is closest to reality.

Companies like Maxim, Microchip, TI, etc, make money off of massive, large sales of their chips (think many, many thousands). I'm sure they have special departments set up, with budgets, just to send out samples, and they probably send out lots of sample orders every day.

They hope that some small percentage of those will someday generate a massive, large sale of something, but I'm sure they are aware that lots of those sample orders are from hobbyists like us. More than likely, the biggest cost to them is the shipping and handling, not that of the chips.

All said and done, it may be better for everyone if you just order samples from the manufacturer, rather than placing an order for 1 or 2 chips from someplace like Mouser or Digi-Key.

And, well it worked for everyone but Ramtron... I'll have to just buy thoes chips...
and figure out how to solder... or get better eyes... :)
