18F family, 40 pin PIC with 64K flash memory - 5v - suggestions please

[Scampy]

I'm running out of memory (32K) on the 18F4580 (I have several large include files for PID routines, AM2302 sensors, etc) and need a chip similar to the 18F4580 but with 64K - any suggestions ?

Hi Scampy,

I am not sure how many of the peripherals you are using on the 18F4580 but take a look at the 18F47J13 family.
I am currently using the 18F27J13 and it is a real treat - especially the Peripheral Pin Select function!

Cheers

Take a look at the 18F4620.
Pretty close to pin for pin with the 4580 and it's $0.11 cheaper
4620: 64k Flash, 3968 RAM, 1024 EEPROM
4580: 32k Flash, 1536 RAM, 256 EEPROM

I use the 4620 quite a bit, for the same reason, more space.

Thanks for the suggestions, I'll take a look at the data sheets later, in the mean time I'll look at consolidating the code to fit the 32K flash

I have used many 18F4620 for huge programs. Love the chip.

Ordered one as a backup in case I can't consolidate the code to less than 32K
