Take a look at the Microchip 24LC64, it has an endurance of 10^6 write cycles and 3 address pins allowing 8 devices to be addressed on a single bus giving a total of 64k bytes of storage.

What is the best solution for data storage on a PIC16F84 ??? I need to store the following: - 255 graphic characters of 6 bytes each. - About 256 bytes of text. Strings, terminated with 0... (I think :-) - A message using the character set (as long as possible) I need the PIC to be able to rewrite any of theese at any time, and many times. (1 million ++ times would be nice :-))) Can i use an external 24LC?? ? Can I then use one larger than 2k ? This was my initial idea... I can store the character-set by storing one byte of each char in each mem page of the eeprom... (If it is banked by 256... Is it ? ) KreAture -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu -- http://www.piclist.com#nomail Going offline?
