LPC1102, World's smallest 32-bit ARM MCU in a 5mm2 pckg

Hi,
ever heard about a 32-bit microcontroller this tiny? I am familiar
with the Silabs devices that are available in similar packages but
this time it is an ARM Cortex-M0 and it has more I/O and memory than I
thought.
10-bit ADC, 4 timers, UART, SPI, 32K Flash and 8K SRAM, really not bad
for such a grain of silicon.

Check it out.

Yes, it's small, in two dimensions...
However, deployed it will need a minimum layer count,
so that Y axis comes at some cost.
If it bumps the layer count on your board, it's suddenly very
expensive.

Can they fit the die into SO16N, or QSOP16 - and so
offer a single-sided solution ?

There are only 4 pads in the center.  Double layers should work, but
you need plugged via.

I think you could route the inner pads out between the outer, with 4-5
mil design rules

I usually limit myself to 7 mil rules.  I wonder what the center pads
are.  If unnecessary I/Os, you can ignore them.  If ground pads, you
can join them with an outer pad.  Anyone got inside info?

Hi,

I was looking for more info too but could not find anything more
specific on the NXP website. Expect to see more next week because NXP
announced to show something at the ESC in San Jose.

Saw it today on the NXP booth at the ESC West. Many people probably
need classes to see the device :)
Documentation is still a few weeks out I've been told. Well, with
production scheduled for later in the year that seems not a big deal.
That much information I could gather:
Will be able to run @ 50 MHz if external clock is provided, bu

... needs an external clock circuit, not just a crystal. Internal
oscillator can be used for may applications.

Can't imagine were this chip will find a new home, after all there are
so many applications that aim for miniaturization and this is the only
ARM based chip that small.

Congratulations NXP!

This part is not for low cost boards.  It is for small devices.
Sometimes, but not always the same thing.

Rick,

you are absolutely right. You can not use an ultra low cost facility
because the device need at the very least a double sided PCB, may be
more layers and a more sophisticated machinery than a soldering iron
and low cost labor. The lowest cost devices are the LPC1111, selling
for 65 cent @ 10k according to the press release.
http://www.mcu-related.com/architectures/35-cortex-m3/92-lpc1100
Still a bit tough for hand soldering but low cost equipment will do an
excellent job with these chips.
