For example, I have used an Atmel 89C51 in a design in the early 90's and that is still in production. No end in sight so far. Because it works. -- Regards, Joerg http://www.analogconsultants.com/

Devices like the new 12Vin/12V I/O Micronas easyLIN will generate a lot of traction. Many of these are one clock or turbo cores. The highest ADC performance devices use 80C51 cores, and dominate metering. The 80C51 will still be (easily) the worlds highest volume 8 bit uC core. -jg

Banking is a way to force it to do more than it was designed to do. Banking adds Issues and slows the CPU down. That said it does work. I would guess that SOC use it since it is popular, Has good tools and has an lot of space to add control register. In the end it is the core you have. Go with it.

A lot of the people here have been around for years - if you don't understand the banter between old hands like Ulf and Lewin, don't comment on it, as it just makes you look silly.
