1. 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).

2. Ei inputs should be tied to Vss (see Section 2.3: Chip enable (E2, E1, E0)).

3. Ei inputs should be tied to VCC (see Section 2.3: Chip enable (E2, E1, E0)).

4. Evaluated by characterization, not tested in production.

1. Compliant with JEDEC Std J-STD-020 (for small body, Sn-Pb or Pb-free assembly), the ST ECOPACK® 7191395 specification, and the European directive on Restrictions on Hazardous Substances (RoHS directive 2011/65/EU of July 2011).

2. Positive and negative pulses applied on pin pairs, according to AEC-Q100-002 (compliant with ANSI/ESDA/JEDEC JS-001, C1=100 pF, R1=1500 Ω, R2=500 Ω).
