Questions answered in these manuals
What is the write protection feature?
The WP pin allows normal read/write operations when connected to ground, but enables write protection when connected to VCC.
How many devices can be addressed on a single bus?
As many as eight 2K devices may be addressed on a single bus system.
What does the WP (write‑protect) pin do?
The WP pin provides hardware data protection; when tied to GND normal read/write operations are allowed, and when tied to VCC the protected half of the array is write‑protected.
How many write cycles can the AT24HC02B endure?
The device is rated for one million write cycles.
