    Hi,

    18F4620 or 18F46K20 (no eeprom)

    18F452 is also pin compatible but a bit old.

    Worse, it's at its End of Life, according to microchip.

    Components don't die.. they slowly fade away. I just mentioned it because there are still millions of them out there.

    With the 4520 being cheaper and better, there is no reason to continue with the 452.

    The 18F46K20 DOES have 1024 bytes of EEPROM...

    What you might be thinking of is the 18F46J11 series... it may not have EEPROM, but you obviously missed what it DOES have instead (which obsoletes the EEPROM completely)... and with an integral RTC as well, it's a winner for a lot of applications... shame it's not supported by PICBasic yet...
