Atmel AT24C08A
The AT24C08A 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 and can be connected to ground. The AT24C16A does not use the device address pins, which limits the number of devices on a single bus to one.FEATURES
