   Does anyone know when the 16F877 will be available for production runs.

Thanks Ray

And when and where can we get a few samples?

Where can we learn more about it«s debugging feature. The datasheet just
say it is available from Mchip and uses the serial programming pins,
consumes one stack level and some program memory.

BTW, I could not reach http://www.microchip.com for the moment.

Thanks in advance

How compatible is it to the 16C77? I have a 16C77 HEX file that I don't
have the source of. I can't do changes to it, except for hex editing
single commands (to not move stuff around). Can I use the 16F877 with
that software?

Memory layout appears very similar.  A few things are changed/added (2
bytes for ADRES, 2 for EEADR, 2 for EEDATA).

Overall, it looks good.

Only thing I picked up right away wrong is that you can't have a
code-protected chip program itself.  That, says I, is the stupidest thing
around.  The reason for self-programming is so that you can update it in
the field w/o sharing the code with everybody who cares to read it from
their chip burner.

Maybe you could disassemble the code ...  I have heard that MPLAB can do it
for you, but to write a dis-assembler yourself should be (and is, I've
'build' one in QBasic for the 16C84 and 17C44) quite easy.

Timo Rossi also did a disassembler which I've used and like.  I don't have
the URL (I found it with Alta Vista or Yahoo) but if you e-mail PRIVATE
.....mtdesignKILLspamspam.....fast.net I'll send you the ZIP file.

I'm not sure why you would use a brand new, possibly more expensive part
in replacement for a 16c77.  The flash parts are going to have a 10-bit
A/D, with 2 registers for the result.  That's the only difference I've
been able to pic (no pun) out of the datasheet since yesterday.  And of
course, the new flash programming specifications.

there other parts now besides this new one that contains this?

THey are also self-programmable and have more internal EEPROM.

Andy, you frighten me. I was just about to start carrier as an embedded
chips programmer, and these nasty self-programmable chips ruined all my dreams
