Data retention(1)

1. The data retention behavior is checked in production, while the data retention limit defined in this table is

extracted from characterization and qualification results.

Device not selected(3),

VIN = VSS or VCC, VCC = 2.5 V

3. The device is not selected after power-up, after a Read instruction (after the Stop condition), or after the

completion of the internal write cycle tW (tW is triggered by the correct decoding of a Write instruction).
