The AT24C512C features a low‑power Standby mode that is enabled when any one of the following occurs:

• A valid power-up sequence is performed (see Power-Up Requirements and Reset Behavior).
• A Stop condition at the end of a valid I²C transaction is received by the device unless it initiates an internal write cycle (see Write Operations).
• At the completion of an internal write cycle (see Write Operations).
