Which are the most common 16 bit microcontrollers on the market today?
Black ones, with silvery connectors Alf
I thought it was a good question, anyone have any real answers?
Motorola 68HC12 I think
Infineon C167 as well
Or Hitachi H8S (nice tools free downloadable from Hitachi).
Or 68k (Motorola counts it a 16bit CPU !)
Or ARM7TDMI (with a 16bit bus => cellular phones/handies)

MSP430 for very low power operation. Max Frequency 8MHz. Only 64k memory map. No external data bus. Lots of different peripherals including LCD-controller,ADC,DAC. Not expensive. Samples available from
MIKE
BTW, did you know
Here's a fight HC12 versus C166:
Nice chip and easy to use in the right context. However, the 3.6V (or thereabouts) max supply voltage really limits their application, unfortunately. So many peripherals require a 5V part. :(

No, cool :-)
Well, name it correctly: 6812 versus C166 => 6812 wins :-)
=> Do not trust a statistic you have not faked yourself ! :-)
Ok, becoming completly OT :-)

Haven't yet found anything I couldn't get in 3V3, equally a small booster in a SOT23 ppkg is simple to add if necessary.

I've been poking around with an idea to build a small microcontroller box... 32-bit is way too much, and 8-bit is a pain in the rear. ;)
I too, am interested in 16-bit uCs... My interest is in one with 16-bit ALU/registers, and some nice onboard components (the latter will be shipped off to daughter boards, so no real specific requests, but the more I can bus to the daughter boards, the less hardware they'll need to carry).
Problem I've found, is that I need room for a tad over 64k (100k or there abouts, I suspect), which seems to be a regular limitation with the 16-bit processors I've looked at.
Anyone know a solid, avaliable processor with 16-bit internals, and a 17- or 18- bit address bus, or at least a reasonably efficient means of faking one. Good range of onchip goodies is a bonus. :)

Oh, I forgot to add... I only need a couple MHz processor clock. Which is my main reason for wanting to avoid 32-bit processors. These are intended to be kits, and high-speed combined with home soldering, isn't always a good mix. ;) That and a minimum of supporting hardware required.

If these are intended to be kits, you need to consider availability of low cost tools, books and knowledge base, so you need a cpu that has been around for a long time with an established track record. The MSP430 would be an excellent choice, but I would go straight to 68k. It's a low speed design, not particualarly fussy about board layout and some variants are static, which means no problem with slow clocks. It's arguably the most generic 16/32 bit cpu around. There are dozens of good books and more good quality tools around than you can shake a stick at, many of them free. Finally, it's a classic cpu architecture. Designed with compiled languages in mind, with few gotchas and a excellent example of how a cpu should be designed, if you are targetted this kit as educational...

The 64180, or Z180 (Hitachi/Zilog). They have the advantage of a plethora of CP/M software availability, which can run directly. The Rabbit is in the same general class, but unfortunately has abandoned binary Z80 compatibility, and so does not have the benefit of the existing software.
