Hi all.
Does anyone know of a PIC that does not require paging? In other words, all memory is contiguous. I'm looking for a 16K (or larger) memory device.
Cheers, Simon.

18F452 is a popular upgrade from the 16F77. Memory is accessible unpaged, though it is slightly more optimal to use paging for the bottom RAM bank.
The great thing is you can recompile a 16C77/F77/F877 application with only a few careful mods and be up and running again, even in PDIP-40. It worked for me. There are bigger parts still in the 18 series.
Regards, Mike.

None of the PIC18xxxx processors have paging. There are 16/32/64K devices in that family (as well as some small memory parts), and some that can expand to address external memory with a full data/address bus.

No no no no no.... An AVR is a PIC without paging AND without just that one single "working" register that everything has to squeeze through...
