... Memory Organization 3256F–SEEPR–10/04 The AT24C08 only uses the A2 input for hardwire addressing and a total of two 8K devices may be addressed on a single bus system. The A0 and A1 pins are no connects. The AT24C16 does not use the device address pins, which limits the number of devices on a single bus to one ...
