Hi
My demo board in cy7c68013A using the i2c EEPROM(24lc128),but the A2 A1 A0 is connect to ground(0 0 0).
Is it possible do not need to change the PCB?
Thanks

Hi,
The EZ-USB uses the EEPROM device-address pins A2, A1, and A0 to determine whether to send out one or two bytes of address. Single byte address EEPROMs must be strapped to address 000, while double byte address EEPROMs must be strapped to address 001. So you should change the hardware.
Thanks,
Prajith
