Absolutely.

The Intel chip is available in 40-pin DIP or 44-pin PLCC package, the Atmel a 20-pin DIP or 20-pin SOIC package.

So they are not even close.

What is your goal? Are you trying to replace one of these devices in a design due to lack of availability, etc?

Looks like Andre has got you covered, with the traffic light project.

You'll want to make sure which ever MCU you decide on, is available in a DIP package.

Unless of course you've had plenty of experience soldering fine pitch packages.

If you have the choice, you should lookout for a Atmel 8051 processor with serial in-system programming (ISP) capability, e.g. a AT89S52, that considerably eases program development.

I´m agree with that opinion.
I used an Atmel familly core with Keil compiler, and never noticed some problem.

The purpose of your original question is unclear. What's your particular problem with 80C51BH?.

Through driver ( like a simple NPN BJT transistor ).
