Flash equivalent for 12C509A

Hi all,

As above. Is there a flash device substitute for the 8 pin 12C509 device?

I don't seem to be able to get a definitive answer anywhere (even Microchip)

TIA

What about the 12F629 etc.? Flash, eight pins and lots more stuff in it than the 12C508.

Can I use 12C509 code in it without modification?

Not quite, but changes should be fairly trivial unless extensive use is made of RAM banking. Mostly removing page-preselect stuff and changing RAM/SFR locations.

There are not now, nor will there likely ever be, flash versions of any PIC with 12-bit core, including the 12C508/9.

Not true. There's a 16F54 and a 16F57, both of which use are flash versions of the 12-bit core.

Indeed, so I see, but they don't seem to be real (yet). The estimate is mid-July 2004. There was also supposed to be an 18F in the 8-pin package but it never made it..
