I received a notice from Digikey that the 28-DIP version of the LPC1114 has been marked as obsolete and is being discontinued after December this year. Here's a link.

Does anyone know if this will be replace with a new MCU or will there now be one less through-hole breadboard friendly ARM microcontroller in the world?

We are contacting NXP, because LPC1114FN28 is in their 10-year promise list. http://www.nxp.com/techzones/microcontrollers-techzone/longevity.html

When I get accurate answer, I will inform.

I've got a reply from the NXP management. http://www.ytsuboi.org/wp/archives/2281

This is great news! Thanks for chasing. This MCU is great for through-hole boards / breadboards (ease of use), also useful as a sub-processor.

Unfortunately 3 years later it seems hard to find a distributor that carries them apart from a few on E-bay, though NXP still report "Active".

The LPC810M021FN8 is "No Longer Manufactured" as well.

Just gone to NXP.COM

and searched through ..

you can buy directly from NXP.

I would suggest EVERY SINGLE MBED member orders at least ONE !!

It shows me just distributors and none of them have any on stock. Did you manage to buy some ?

The TSSOP28 ones are available at digikey.

I get that but it wasn't the point. The point was that while it lasted you could get an ARM processor in DIP format that fitted into plugblock or stripboard without the need to muck about with adaptors.
