#163625 - try another manufacturer
Responding to: ???'s previous message
Have you pulled the WP pin low?
Try the atmel AT24c64 chip, usually eeproms are straight forward and the problem might be in the chip itself.
You can also test the chip by writing to it by normal programmer like the TOP2005 to see if it is ok.
