'Atmel claims to have first 8-bit RISC processor???'

In the Sept 12 issue of EDN magazine ("Out in Front" section, page 21),
there is a press release from Atmel claiming that they have the FIRST 8
bit RISC processors?  Atmel calls this line of processors there AVR
series, and the first one is the AT90S1200.  For more details wait for
the Sept 12 issue to appear at http://www.ednmag.com/.  (It doesn't seem
to be there as of 9/18)

I find this to be quite odd because I've always thought of MicroChip as
having 8 bit RISC type processors?  Is this true??  Or is Atmel just not
aware that MicroChip exist? :-)

Any thoughts?

Microchip marketing thought they could get away with calling the PIC a
RISC chip.  Atmel marketing apparently disagrees.  So what?  You're
not listening to marketing departments anyway, are you?

I saw this as well and the claim even includes a reference to it's
Harvard Arch.  as well as something about being able to ' directly
address 8 Mbyte of program memory.'  With a 16 bit instruction?

Also claims to have an ANSI C compiler that as you read later in the
article will not be available until.....there it is... October from a
3rd party vendor.

No RAM?

But most of the specs read like a PIC

Hi,

I find the RISC description odd - the smaller ones have 83 intructions,
the larger ones have 133 instructions.


Still, I will be getting one to evaluate (play with) as soon as they
come out. For anyone interested here are some salient specs:

- 20 pin
- 1K flash program memory
- 128 bytes EEProm
- 32 x 8 general purpose working registers
- 15 i/o lines
- 8 bit time and prescaler
- Analog comparator

oh yes, I'd better not forget the "programming lock for software
security"  :-)


The 2312 is much the same, but also has 64 bytes ram, Full duplex uart,
10 pit pwm, 16 bit counter timer.

There are also a couple of 40 pin parts in the family.


Regards,



Mike
