Hi, I need a EEPROM to store data permanently, ie with power removed, and then to be able to read it at a later date. After that, the data can be over written with new data. The 24AA04/08 seems ideal. I'm trying to interface it to a 16F84. Has anybody out there any experience of doing so, or even done all the hard work. How many I/O lines do I need? Any help would be grateful, either to PICLIST or direct to my E-Mail address. Many thanks in advance. Richard Austin
