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 Industrial and Automotive grade only; not applicable for Commercial grade. T
3. Specified for Automotive grade (A2) only; not applicable for any other grade. T
Key Timing Parameters by Speed Grade
Note:
Each of the -25D and -3D speed options is individually backward compatible with all the timing specifications for slower options (ie. -25D
complies with specifications for -25D, -25E, -3D, -37C, -5B). -25E, -37C, and -5B shown for reference only.
