1. The test flow guarantees the AC parameter values defined in this table (when V
CC
= 1.8 V or V
CC
= 1.7 V)
and the parameter values defined in AC characteristics tables for M95512-W (when V
CC
> 2.5 V).
2. If the application uses the device at 2.5 V ≤ V
CC
≤ 5.5 V and –40 °C ≤ T
A
≤ +85 °C, please refer to Table 20
instead of the above table.
