There are so many companys that make micro processor(8051).
Does anyone share his viewpoint, which brand is better in terms of which aspect?

8051 brand

Hi,

I would look at least at three different companies about 8051.
If you need the fastest and best analog features, look at Silabs. They have a great variety with some exceptional features, outperforming any other 8-bit architecture I know with 100 MHz single cycle devices.
If you need more "standard parts" and top performance is not as important as low price, you want to look at Philips and Atmel.

While the standard 89C5xx or 89S5xx devices are very similar Atmel has a few advantages there. These devices are usually not really low cost.

Also have a look at the Philips LPC900 family which can compete in many things with the AVR but is still a 2-cycle 51 core.

So, for the high end performance go to http://www.silabs.com/tgwWebApp/public/web_content/products/Microcontrollers/en/index.htm

For the best price performance probably the LPC900 family from Philips

For the best offering in a 44-pin PLCC standard 89S5x device or if you need e.g. a Flash device with CAN you might want to check Atmel.

Hope this helps, Bob

There is also the TINI line from Maxim, if you want Ethernet connectivity (you
need to add an external PHY, though):
