Hi,

Anyone know of a pic with integrated eeprom?
Im not talking about the usual 256bytes, but rather like an integrated 25lc512.

Thanks

Long ago Microchip had an 8 pin processor with two dies inside. An 8 bit processor and a 16 byte EEPROM. There were connected with a pair of I/O pins that were not brought outside the chip and used software I2C communication. PIC12CE673. This was before they started integrating the data EEPROM on-chip.
Probably not what you are looking for.

Thats the "concept" im looking for but with at least 256kbit and hopefully 512kbit

thanks.

But (of course) remember this is flash memory, not "EEPROM", so no single byte erase. Just page based operations.

If you want a traditional EEPROM, I'm afraid you need to connect it externally.

Im working on a very specific use dataloger.
so far ive reduced it to a single 16F1825 and a 25LC512 and 1 sensor.
i think PIC18F97J60 is an extreme overkill... but its worth looking at pics with large flash..

i was thinking it would be awesome if i could do a complete single chip solution.

Thanks anyways.
