Hello, i brought two 24c512 EEPROM and i can interface single EEPROM but don't know how to it with twice or more.

any help ???

ps. image or link will be better.

thank you...


You can change the address of a chip using the pins 1 and 2. Base address usually is 0x50. If you connect pin 1 of the second chip to 5V it's address changes to 0x51.


in that case, i can't use EEPROM Database right ?


You can connect up to four of these chips to on single I2C bus.

What's a EEPROM database in this context?
