    Default Picbasic/18F/internal data-EEPROM capacity > 1kbyte?

    Hi,
    I am looking to better the 18F46K22 for internal data-EEPROM capacity - which at 1kbyte is already quite large.
    A trip round the forum and Microchip's 'Configurator' shows nothing bigger.
    Is anyone aware of an 18F with this parameter >1 kbyte at 8-bits wide ?
    Thank you!

    SPI eeprom is cheap and easy to use, dont let that discount otherwise more appropriate PICs

    flash is also an option depending on your change / retention requirements , also very cheep

    Like towlerg already said above, the external SPI EEPROM is the way to go. It is also easy to implement.

    You can use PIC internal FLASH memory to store data, using READCODE/WRITECODE/ERASECODE.

    True, but be aware of limitations of write operations to code memory.

    Many thanks, friends, for the collective advice - all of it valuable.

    You have solved the problem!

    For this particular application, the writecode/readcode will get me out of trouble for prototyping; and in the revised circuit board I will use an external EEPROM.
