Input/Output Capacitance
Electrical Characteristics & AC Timing Specifications
Refresh parameters (TOPER; VDDQ = 1.8 V +/- 0.1 V; VDD = 1.8 V +/- 0.1 V)
Notes:
1. If refresh timing is violated, data corruption may occur and the data must be re-written with valid data before a valid READ can be executed.
2. Specified for Automotive and Industrial grade only; not applicable for Commercial grade. T
3. Specifed for Automotive grade (A2) only; not applicable for any other grade. Toper may not be violated.
