Can you suggest me a microcontroller...

[hkBattousai]

The requirements are :

-Have to use multiplication instructions in the program code.
-There must be at least 20 I/O ports
-At least 5 MIPS
-Will work under high temperature and vibration

I used to use PIC, but this time I need a faster one with MUL instructions.
Waiting for any answer or suggestion.

If you are used to work with PICs I think the most suitable micro for you would be a dsPIC. This device is a hybrid between a conventional microcontroller and a DSP. It is actually a 16-bit micro with a DSP engine, so it will fit quite nicely in your requirements.

As you are used to PICs, you'll find it easy to understand.

In the other hand, if you don't mind learning new architecture, i would suggest the MSP430 family from Texas Instruments. These are more efficient and cheaper than the Microchip's ones.

I encourage you to take a look at their datasheet in TI's website: https://www.ti.com

Hope being of help.

The 18F PICs have a hardware multiply. The 18F2525 is a nice little PIC that can run up to 10MIPs.

Thank you for your guidance.

I decided to use PIC 18F4550 because of its USB port interface support.

I am going to make an investigation on dsPICs. I have another project in my mind which requires a DSP card. Maybe a dsPIC will be sufficient instead.
