RE: [lpc2000] Re: SD, MMC, CF, and hard disk on one chip

2004-07-27 by Joe Hlebasko

Gus,
It also depends on volume of the product. If I was planning on selling low
volume (<150) per year then I think a solution like your chip could make
sense. Any volume higher (>150) it would make sense to purchase a source
code library.  A $25 chip cost is a fixed cost to a product.  The source
code cost is paid for, and would not incur on going costs to theproduct.
Benefits include: less board space, you have control of the source to
add/remove features as needed, less power consumed by the board.

So a lot of this comes down to what the are the development constraints:
time (do you have the time to incorporate FAT code into your app) and target
product cost.

I am considering to purchase one your development board to use for a test
platform for my code.
