differences between 16f628 and 16f628a

Started by knalkeez January 29, 2004
Until now, I succesfully used 16f628's for my robot-projects. I use an el-cheapo parallel-programmer (SHAER) and use
in-circuit-programming. So far so good.
Yesterday I ordered 16f628A chips, 'cause they're a bit cheaper, and usually the 'A' stands for 'improved'.
But after reading some articles on the net, i got a bit concerned that the 'A'-version might have different programming-characteristics,
and that my programmer won't be able to do the job (I haven't tried it yet, but I like to know before I waist hours trying). Does anyone
know of these (or other) differences between the normal and the 'A'-version?

Thanks in advance,

Kees Stenekes



The difference between 628 and 628A is only on the fuze byte, you need to
programmer with the option 628A on your
programmer and the software is the same. Regards,
Gilmar

Microchip has a datasheet that discusses migration from 628 to 628A
and indicates the differences. Flash programming doesn't appear to
change like it does between the 16F877 and 16F877A.

Just search Microchip for PIC16F628A and there will be a migration
document listed.
