It stores configuration parameters, calibration constants, and small firmware patches that need to survive power loss. The exposed-pad package (2x3 mm) is a space-saver for tight PCB layouts.
The 1.7 V minimum supply works with modern low-voltage MCUs and legacy 5 V buses alike.
The exposed pad package (supplier device package 8-UFDFPN, 2x3 mm) is a leadless package.
It is 64 Kbit, organized as 8K x 8 bits (8192 bytes). That's enough for a few hundred configuration parameters or a modest lookup table.
