gnupic: Thread: Documentation wanted

Dear folks,

I'm looking for the programming specifications of the following very new
or very old PIC chips:
12cr509a
rf12c675f
12cr62
16c84
16cr620a
16f639
16f913
18f2681
18f6310
18f6625
18f6721
I need the info for the Pista project.

I cannot found them on Microchip web servers.
(Send a mail to their webmaster and complain that the previous
version of search [based on the Google engine] was much better
than the current one.)

Can somebody send me some pointers?
Or do you have a tattered and dusty copy of the elder PDF files?

Gabor

just checked it out & found the 12CR509A using the Data Sheet Finder
near the top of the opening page.

I need not data sheet but the programming specification.
(I.e. ICSP commands when Vpp pin is pulled up to 13 V,
checksum calculation, user ID location, etc.)

I think 12cr509a 12cr62 16cr620a are Mask-Rom.
           ^        ^      ^
So there are no programming specification. :-)

Oh, my God!
You got the point. :-)
Thx.

Since some of the chips you specified were CR, they are "masked ROM" parts
and not programmable.

I have found data sheet for 18f6625 and 18f6721 (file also includes data 
sheets for 18f8625 and 18f8721):

For 18f6310:

Also i have found datasheet for rf12f675f ('f', but not 'c'):

I'm confused a bit.
So far Microchip published two different docs for each chips:

- A "Data Sheet" that describes how the chip works after you loaded your
  application. It is for normal (application) developers.

- A "Programming Specification" that says _how_to_load_ your program into
  the internal Flash, and how to erase it.
  This is for people who develops PIC programmer equipment.

Now I reread 39627a.pdf and I found some info about programming.
But I don't know if it is full.
At least I found absoultely nothing about User ID.
I guess there must be an other (much shorter) document that
describes the programming algorithms detailed.

Ahmm! I checked out those devices for prog. information and the company claims that they are "future products"! How do you expect it to provide data for prog. information? Besides, how can you test your possible prog. algorithm even if samples of the specific devices do not exist! This is what i think according to the official pages of the company. But in case the information exists I would like to have it myself as well.

One solution to overcome your problems is to modify your existing algorithms relative to similar devices i.e. for 18F6720 you can use ww1.microchip.com/downloads/en/DeviceDoc/39583b.pdf

I asked about these chips because the latest MPLAB IDE already supports them.

Fortunately I have not implement any algorithms.
I develop a utility for an "off the self" PIC programmer called PICSTART Plus.
I just have to know what built-in algorithm to choose.
(Currently there are some 25 ones.)

No, I cannot test if programming/erasing is successful for all possible
PIC chips including the obsoleted and future products.
This is mostly done by Microchip.
I just want to know why certain chips are not supported by PS+
according to Microchip. It is because actual firmware really unable
to produce the appropriate waveforms or just a given chip is not
packaged in DIP at all so it could not put the ZIF socket of PS+?
(Buy the more expensive programmer. ;-)
In the later case I could add this PIC to my repertoire
with instructions how to make an adapter.
