The SCL enter is accustomed to optimistic edge clock facts into every EEPROM gadget and harmful edge clock details outside of each and every gadget.

SERIAL Data (SDA): The SDA pin is bidirectional for serial information transfer. This pin is open-drain pushed and should be wire-ORed with any quantity of other open-drain or open- collector equipment.

DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are gadget tackle inputs which might be truly hard wired using the AT24C01A in addition to the AT24C02. As quite a few as 8 1K/2K units may possibly be dealt with which has a just one bus procedure (machine addressing is mentioned intimately beneath the Device Addressing section).

The AT24C04 employs the A2 and A1 inputs for demanding wire addressing plus a over-all of four 4K units may well be dealt with on the one particular bus process. The A0 pin is known as a no be part of and may very well be linked to floor.

The AT24C08A only performs by using the A2 input for hardwire addressing moreover a total of two 8K models might be solved about a just one bus system. The A0 and A1 pins are not any connects and could possibly be joined to ground.

The AT24C16A will not make the most of the gadget deal with pins, which constraints the quantity of models using a solitary bus to one. The A0, A1 and A2 pins are not any connects and will be linked to ground.
