I'm doing my first steps with the ATSHA204A crypto EEPROM. I created a little test application with a PIC16F as the host for I2C communication and the ATSHA204A EEPROM. First I only wanted to establish the communication over I2C bus and read out count, status/error and the 2-byte CRC. For this I am using the factory default of the I2C address which should be 0xC8 (like described in the Factory Default Test Data document). But the device does not acknowlegde this address at all (see attached screenshot). I don't know what I am doing wrong. Am I using the right address? Or is there anything else I have to consider when addressing the EEPROM?
Thanks for any advice!
