M24M02E-F only 1 Mbit available?

Hello,

We wanted to replace an M24M01-DFCS6 memory (1 Mbit) with an M24M02E-F (advertised as 2 Mbit) available in a WLCSP5 package.

After starting the driver implementation, we realized that the sections “Device Type Identifier”, “Configurable Device Address”, “Software Write Protection”, and “Identification Page Lock” occupy more than 1 Mbit…

Is there actually a way to access the full 2 Mbit of this memory for data storage?

I feel like I've been misled...

Thanks

    Bit 4 = 0 selects memory. The others have bit 4 = 1.

    A17=1 addresses the upper Mbit of memory.
