(1) Typical values represent most likely parametric norms at V_DD = 3.3V or 2.5V, T_A = 25°C, and at the Recommended Operation
Conditions at the time of product characterization and are not ensured.
(2) The V_DD2.5 is V_DD = 2.5V ± 5% and V_DD3.3 is V_DD = 3.3V ± 10%.
(3) Allowed supply noise (mV_P-P sine wave) under typical conditions.
(4) Recommended value. Parameter not tested in production.
(5) Measured with clock-like {11111 00000} pattern.
