So, then, which other architecture offers 2nd source? FYI your own employer does not seem to believe that the 8051 is obsolete: http://atmel.com/products/8051/default.asp Quote: "Atmel offers a broad range of microcontrollers based on the 8051 architecture. ..." 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/

Maybe I should put the signature in BOLD letters... -- Best Regards, Ulf Samuelsson This is intended to be my personal opinion which may, or may not be shared by my employer Atmel Nordic AB

I know it's your personal opinion, just wanted to make a point about why the 8051 architecture is still widely used. And unless another 2nd-sourceable series appears it will remain in use. That would be my personal opinion, and that of a whole lot of others. -- Regards, Joerg http://www.analogconsultants.com/

Hasn't the ARM7 been call the "8051" of the new millennium. Too bad the ARM7 is just the cpu and not the entire configuration i.e. peripherals. donald

The prices of both cores are asymptotically approaching zero, but they really don't 100% occupy the same application space.

The 128K in this thread is at the top-end of the 80C51 range, (ASIX make some larger, with Ethernet) but there is a LOT of R&D effort going into 80C51 in the far-east now : Companies like Winbond, Megawin, Myson, Micronas, Coreriver, STC, Syncmos, ABOV, (etc) are expanding their offerings. 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

Yep, it sure will be. I even found one in our pellet stove. -- Regards, Joerg http://www.analogconsultants.com/

Only if 2nd sources are coming from companies like Winbond. Else, no. Just my humble thoughts.

I like the CPU Core. 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.

Here's a bit of unrelated free advice: When you join a newsgroup, remember that you are joining an established community. 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. And learn to spell "you" - you'll be amazed at the increased level of respect you get. mvh., David
