Here is the code I used for a AT24C512 (64KB) EEPROM.
 


[code]
    ' Write origData to EEPROM address addr_LSB,addr_MSB 

    I2CStart SDA
    I2CSend SDA, $A0
    I2CSend SDA, addr_MSB
    I2CSend SDA, addr_LSB
    I2CSend SDA, origData
    I2CStop SDA
    PAUSE 5 

  

    ' Read byte back from EEPROM address addr_LSB, addr_MSB 

    I2CStart SDA
    I2CSend SDA, $A0
    I2CSend SDA, addr_MSB
    I2CSend SDA, addr_LSB
    I2CStart SDA
    I2CSend SDA, $A1
    I2CRecv SDA, readBack, 1
    I2CStop SDA
 
[/code]
