Re: Moving from 8051 to AVR

Single clock C51 FLASH variants hit 33MHz, 35MHz, 50MHz, 66MHz, 100MHz
from various vendors - rather faster than the AVR.

So, why bother ?

Rehashed 8051 is a bit like your grandmother trying on a bikini.
Not a pretty site.

AVR was designed from the ground up to be a modern processor.

Why would a rehashed 8051 be THAT bad?

The 8051 is a great architecture, I moved from the PIC to the 8051/2
and have never looked back. The single cycle cores add life to the 8051
line and it still is a viable competitor to other 8-bit MCU's decades
after its first incarnation.

It has tons of free compilers and assemblers out there and lots of
example code. It is more mature and is easy to find decent information
on it.
