The AT24HC04B uses the A2 and A1 inputs for hardware addressing, and a total of four 4K
devices may be addressed on a single bus system. The A0 pin is a no-connect.
WRITE PROTECT (WP): The AT24HC02B/04B have a Write Protect pin that provides hardware
data protection. The Write Protect pin allows normal read/write operations when connected to
ground (GND). When the Write Protect pin is connected to V
enabled and operates as shown in the following table.
