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. 73/ Bob - W5BIG ----- Original Message ----- From: "Michael Studer" <[EMAIL PROTECTED]> To: "Elecraft" <elecraft@mailman.qth.net> Sent: Thursday, November 04, 2004 1:37 PM Subject: [Elecraft] PICs re-writable? > Since I now have a pile of old Elecraft PIC chips I got to wondering if they > can be erased and reused?
