FAQ

How does the Write Protect (WP) pin function?

Connecting the WP pin to VCC disables all programming functions, protecting the entire array. Leaving it unconnected or connecting it to GND allows normal read and write operations.

What is the maximum page write size?

The device supports a 128-byte page write mode, allowing multiple bytes to be written in a single sequence without intermediate stop conditions.
