[Elecraft] PICs re-writable?

2004-11-04 Thread Michael Studer
Since I now have a pile of old Elecraft PIC chips I got to wondering if they 
can be erased and reused?  I know they have code protection that protects 
them from being read.  But I wonder if they can be erased and reused?

I am probably dreaming. :)

Hi Mike,

The chips that have part numbers like 16Cxxx or 18Cxxx are not erasable.
Those with an 'F' instead of a 'C' are erasable. The 'F' is for 'flash', an
electrically erasable form of memory.

Circuits using flash memory can be designed so they are reprogrammable in
the field, without disassembling the unit. This makes it possible to get
firmware updates over the internet.
