3. 2k ram
4. 4 * 16 bit timers
5. 4 * 16 bit PWM
6. Power on reset
7. 8 * 10 bit ADC
8. watchdog timer built in

For that price you will be lucky to get a 16bit micro.
I have just used a ST ST72F521R9 micro - it is 8bit but has a good can cell and is worth looking at.
price was about $3.50 for the 60K variant.

Perhaps some models of the Hitachi H8/36xxx series are adequate.

See this news release for a nice overview (including some price info):
http://global.hitachi.com/New/cnews/E/2002/0905/index.html

Personally I have worked with several models of the H8S series (which are a bit larger brothers), and I like them a lot. Nice is the possibility of prototyping on flash based devices, and go in production with rom based devices.

Hitachi also has very nice development tools, but these are available from several other vendors as well.

If this sounds interesting, I would suggest contacting a local Hitachi representative for more info.

I know a microcontroller who meet almost all those requirements, which is in production, but I don't know the cost :

Infineon C167 microcontroler family

The C167 is very similar to the ST10, the price would be 2-3 times what you are after

Hello, snsriram79

Now some news from microchip but it isn't official.
It from internal man inside of microchip.
They have plan to reveal their dsPIC product in the maket around
Jun/July this year.

Good luck.

I don't think there are any dsPICs in the market yet.
When will they be released? Have you heard any news from your "internal man"?

Re: 16 bit mcu

Well... Well ..

It looks what you want is only avalaible with TI's MSP430
a native 16 bit architecture .. and a very low price .. !


If you need more insight let me know!

I don't think there is any MSP430 with CAN controller as he asked for.

The only two MSP430 with 2 kB RAM or more and 4 timers or more is:
MSP430F448 Approx. 1KU Price (US$): 6.47
MSP430F449 Approx. 1KU Price (US$): 7.03

But they don't have built-in CAN controller.

Re: 16 bit mcu

Analog Device's ADSP-21992 a 16-bit fixed point DSP.
It has 14-bit 20MHz ADC and CAN bus controller.

The temperature range of MSP430 is only: –40°C to 85°C, so this MCU is not really an option.

Anyway this topic is 10 months old, so he have probably found a soloution.
