Where to buy LPC 1768?

05 Nov 2010

I am a bit confused.

There is this nice notebook entry explaining how to go ahead from a prototype.

http://mbed.org/users/chris/notebook/prototype-to-hardware/

Now I have been searching in Google trying to find a store or something where I can buy the chip in the Netherlands, but somehow I do not find it.
Where can I buy it? Or should I look for something else/another term or code?

edit; opps, sorry. Wrong answer

chip? The mbed is a module containing a LPC 1768 chip.

There are other LPC176x modules for sale too.

Using a bare chip is not what you want to do for rapid prototyping which is what mbed is all about.

Hi Ton,

If you want to buy the chips to use in your own hardware design, try NXP's distributors, see http://www.nxp.com/profile/sales/europe_dist/index.html. Arrow, Avnet/Silica and Avnet/EBV have sales offices in the Netherlands. These would however not be interested in selling you small quantities.

Your best bet if you need only one or a few would be Farnell, although they appear to be out of stock right now: http://nl.farnell.com/nxp/lpc1768fbd100/mcu-32bit-arm-cortex-m3-100lqfp/dp/1718549 . It's possible to buy from Farnell as a private person, see http://nl.farnell.com/images/nl_NL/pdf/Particulier_voorwaarden.doc

Hi Ton,

you can get them from Mouser (they have some on stock) . They ship worldwide and have very competitive prices. I'm in Switzerland, and i buy almost all my components either from Mouser or from Digikey. Even with shipping costs etc. included it's almost always a lot cheaper for me than buying from local distributors.

Their localized site for Netherlands is: http://nl.mouser.com

Best regards

@Steve: I own a mbed and am aware of what it is. I think it is rather expensive to put the module into a low budget project. Therefore I was looking into using the chip with the bare minimum of components. Asuming this will drop the costs.

@Others: thanks for the references.

I like to use http://www.findchips.com to track down chips.

None of those have them. Is there a compatible substitue that MBED compiler will also work with? I cannot prototype with a device that wont be available to migrate to production.

Would it be possible to allow the compiler to target a few different flavors or something?

Use LPC1769. It's almost exactly the same except it can run at 120 MHz.

Hey Igor

Is it pinout the exact same? Also is it possible to use the online compiler to generate code for that chip? I dont want to buy additional compilers or toolchains.

I use www.farnell.com for nearly everything these days.

LPC1768:

1+ £7.43 10+ £5.76

they obviously do all the passives and cystals too.

I don't have shares in them.. I've just found them reliable.

www.farnell.com

Does not have stock of this part. It could be months before they get them in stock. Actually Mouser.com told me their order of them is not due in until June 20th!!!!

All LPC1769/68/67/66/65/64 use exactly the same pinout. The differences are in memory sizes and some peripherals. See here for details.

Except for the maximum rated frequency, 1769 is the same as 1768 and will run the same binary without any modifications.

Digikey in the U.S shows 260 LPC1768's in stock and 5966 LPC1769's in stock. Very little price difference.

www.digikey.com

So at least they are available, might just have to pay more for shipping.

Best regards,

Mike

Erm...

Farnell say they have 500 arriving in 8 days on the site. Like I say, i don't have allegiance to them.. just trying to be helpful.

05 Apr 2011

Yes digikey has 260 of the ball grid version but none of the qfp100. I may try the lpc1769. Thanks! !!

Have you looked at LCPXpresso board ? It costs half the price of mBed and it include LCP-Link & compiler.

05 Apr 2011

No I havent but I will check that out. I enjoy the "magic" mbed chips functionality but I dont make use of it much and certainly wont on production so a basic bare metal board that has a way to compile is all I'm looking for.

Thanks

Well then LCPXpresso could be a good candidate for you. It's almost bare metal board (has Ethernet Phy on board). Comes with CodeRed IDE & LCP-Link which is a Jtag that works only with CodeRed IDE. It allows full debug. The LPC-Link can be used with other or custom board too but only CodeRed compiler can be used with it.
