Freescale has introduced the Kinetis KL02, World’s Smallest ARM Powered® Microcontroller

Only 1.9 x 2.0 mm, the Kinetis KL02 MCU features include:

[quote=Freescale]48 MHz ARM Cortex-M0+ core, 1.71-3.6V operation
Bit manipulation engine for faster, more code-efficient handling of peripheral registers
32 KB flash memory, 4 KB RAM
High-speed 12-bit analog-to-digital converter
High-speed analog comparator
Low-power UART, SPI, 2x IICI2C
75cents Cost (in 100k Qty)[/quote]
Link to release page

Can't wait for an ultra compact evaluation board

A bit like a small PIC32 but fewer peripherals. Not sure why either is interesting LOL

Because it is small and cheap enough to replace most 8, 12, and 16bit processors.

Does that not also apply to the cheap PIC32 chips?

Also, does it have 5V-tolerant I/Os?

Other snag I see is that it's Freescale. Reckon they'll be more open? Follow JTAG properly? Provide (free) support? Stick to standards?

Not for me, thanks.

Thanks

Don't get me wrong, I love the PIC32, but these ARM chips are in a whole different league. Edited by djuqa 2013-03-01

In what ways?

So far none at all have been mentioned and questions remain unanswered...

For some embedded applications that amount of grunt in such a small package is impressive. When PIC32 is released in a 3mm Square package, I will be the first to embrace it as well.

David,

As impressive as these ARM devices are, I cannot see myself using any unless they are attached to a header PCB.. 2mm x 1.9mm is smaller than the 10uf cap that most people are struggling with on the CMM. and it has 20 pins (by looking at the picture) or should I say `BALLS' within that confine.

Is the 1.9x2.0mm size accurate or another example of "the US" not converting imperial to metric correctly?
I cannot say I have ever seen a ruler that split mm any more than into 1/2mm steps and they are hard to distinguish at that.

Regards,

Mick

I suspect the size is correct as it is referred to as a "wafer level" chip so I guess that mean "un-packaged".

I imagine it is a bit like those "black epoxy blob" chips you see inside digital watches and calculators etc.

Either way, I don't think I'd be having a go at mounting one unless someone came up with a header board and in any case, the 100 pin TQFP is enough for me at the moment.

In any case it IS exciting... I can see these appearing in eBay and other places mounted on small PCBs with 4 legs as dedicated `do-it thing-a-me-jiggies' to add to your design easily... Say mini maths co-pro with or whatever they are programmed for.

And selling for a couple of shekels including postage.

Bear in mind it's not very fast and has only small RAM plus very few I/Os. Don't get too excited.

I have just worked on an ULTRA-Small design using an 8051 Core, the ARM would have been same size but have a lot more grunt.
The PCB for the entire controller had to be less than 6mm x 8mm due to the nature of the module.

JohnS, I provided the info as this is the MicroController section, I thoguht some of the BackShed brigade MAY be interested especially as ARM processors are the most widely used 32Bit MCUEdited by djuqa 2013-03-03
