Where do engineers go to browse VLSI chips ???

Hi, I'm an amateur designer and was wondering, if theres a central
forum where manufacturers and engineers converge to find their ideal
chips, adapters with the right prices. Is there an online forum, or
organization for it? Or do they all just hire consultants who browse
the web directories for semiconductor makers, ask them for quotes and
compare?

If you needed to browse chips of a certain functionality, apart from
newsgroups and google, where would you head?

I tend to do the evaluations myself.
Regard it as being part of the trade.
What chip are you after ?

What chip are you after ?

I was evaluating 32-bit ARM-based SoCs for running Linux, Ive settled
on the EP7312 now. Theres the search for DRAM chips, flash, adapters
for LQFP to DIP(or evaluation boards), ethernet chips (maybe the
rtl8019 will do), LCDs (the cheapest 320x240 or 640x480 black n
white), tokenring chipsets if they still exist, OEM compactflashes in
bulk, bluetooth and 802.11b interfaces etc.

The search for the ARM soc took me about a month of checking reviews,
datasheets and emailing the companies asking for 1K unit prices and
sample prices. So I figured surely engineers would have a centralized
database like the IC Master or Chipdir for passive analog electronics
to search, and companies in their best interest would post their data
in a similar yellow pages type directory. I still doubt every
engineering group goes through the datasheets of every available chip
and wait for the price quotes for a few days in email. I must be
missing something.

From my home-page, try the following (and let me know if they are still
active and usefull):

1) Datasheet Locator is a free electronic engineering tool that enables
you to locate product datasheets from hundreds of electronic component
manufacturers worldwide. If you already know the manufacturer, this is
an excellent way to browse datasheets for either semiconductor
companies or component makers.
http://www.datasheetlocator.com/

2) FindChips aims to perform the fastest, most complete distributor
search available today on the internet. After you enter a part number
(or substring), FindChips.com will simultaneously query over 20
distributors, and return the responses to you in real time, in the
order completed.
http://www.findchips.com/

3) Free Trade Zone is Partminer's answer for researching components,
shopping for them online. Includes Research, Find, Quote, Buy/Sell
capabilities. Subscription fee, I can't remember how much. Some
services are "free", others available through "demo" programs. This is
likely to be just what you are looking for, if you can afford it.
http://www.freetradezone.com/

4) Electronic Engineer's Master is the worlds's largest database of
electronic manufacturers and products.

I hope this helps

Hey thanks a million. The findchips.com site was especially useful and
Ive found most of the ICs I needed.
