[PIC]: Enhanced PIC16: A new PIC architecture from Microchip

Hi,

I heard of PIC16F1000, which is a newly announced (well not official
yet I guess, as I can't find any info on Microchip website)
architecture.  Those who went back from MASTERS 2008 has anything to
said about this new architecture? When it will be in mass production,
price etc etc ?

Thanks & best regards,

And from what I heard:

This new architecture has some enhanced features over the PIC16
architecture, namely

1) Increase the maximum program memory: can address up to 32K (vs 8K of PIC16)

2) Increase the maximum data memory

3) Increase of hardware stack level to 16.

4) Reduce the penalty for paging/banking
    - by introducing new BSR register. Hence the old PR0/PR1 is no more exist.
    - by introducing new MOVLP instruction.

5) Automatic ISR context saving for W, STATUS, BSR, FSR0, FSR1, PCLATH.

6) Has 2 indirect RAM accesses through INDF0 and INDF1. Support
pre/post increment/decrement.

7) Relative branch (signed and unsigned offset).

8) Stack over/underflow cause Reset.

9) Stack can be accessed via SPTR and TOS.

Thanks for the information. Having banking overhead reduced sounds very nice!

It's a souped up PIC 16 architecture.  It's a rather different memory layout
with some differences in the core.  They really should have given it a new
name other than 16F.  It is still a 14 bit core based on the existing PIC 16
architecture.

I think PIC16H would be a better name.

What's in a name?

Actually ask a marketing guy and he'll tell you - a hell of a lot!

A lot of confusion when it came from Microchip.

Yes, I'll talk to them to find out...

Thanks Olin. Sound like I have to contact local Microchip office to
find out the answers.  I will see what they have to say.

Olin,

Do you think there is room in the market for a super 14 bit PIC?  I
would imagine that the majority of new designs will be 3.3v based, and
