at24c64 interfacing

Hi ....

I m working with Microchip controller PIC12f675 and want to interface it with serial EEPROM AT24C64. However have no idea how it could be done ....

If anyone could help please ...

Thanks in advance.
 

take a look at the AT24C64 datasheet. it shows the 2-wire interface protocol which is also called I²C. You can find lots of bitbang code for this on the web. there are also pull-up resistors needed on the data and clock lines. I believe microchip has an applications note on interfacing to an I²C device. It is a bit complex.

You may not want this advice but I'd look at using eeproms using SPI instead of I²C - it is much easier to "bit bang".
