Post by thread:[PICLIST] Obsolete part rumors...

Hi Darrel One of my customers heard from Future that the 16C71 is going to be obsoleted soon. He asked us so I called the so-cal Microchip office. The person who answered the phone said it is not on any lists she had so we should consider it still in production. Digi-key told me the same thing. Now my customer is worried and concerned. Is there some way you can find out the true story here for us? We would appreciate the right answer. By the way, the person at Future suggested using the 16C711 as it is cheaper. I noticed that it has twice the program memory and also twice the ram. Do you know by any chance if '71 programs will drop right in and run or do they need to be massaged around a bit to account for the larger amounts of memory? Thanks for any help you can offer!

The 710 is 512 words and the 71 is 1024 words. The replacement for the 71 is the 711 and it is the to the 71 as say a 16C74A is to a '74. A direct replacement with the PWRTE bit inverted, uneraseable code protection and brownout added. It's the '715 that >has twice the memory.

Tom, Last week in the MChip seminar they said that this and other popular parts will be replaced by its (slowly..) appearing flash versions. Also, said that in one year they'll be producing a cheaper (with a new fab process) version of the 16F84. BTW, the seminar was a big bad joke. I don't understand where they want to go in trying to teach analog filtering theory (in a *PIC* seminar) in three hours... And showing the poor FilterLab software to engineers with years of experience on designing all kind of filters... It seems that they need to sell their new OpAmps... I guess how many of the 150 assistants will return to a Microchip seminar next time. Regards, S.- {Original Message removed}

Tom, I have a customer whose code is set up to use either chip. Only the fuses were different, as I recall.

Fine except for one thing. Due to the fact that what Microchip calls Flash is more like what everyone else calls EEPROM Microchip's flash parts take a long time to program. It will be very tedious when I have a batch of ten to do. Brian Gregory. briangspam_OUTcix.co.uk -- http://www.piclist.com hint: The PICList is archived three different ways.

The 711 is directly upward compatible with the 16C71 except for the config word changes I mentioned before. (BODEN added, PWRTE reversed, code protection uneraseable and more secure.)
