Note: (1) Under all conditions VDDQ must be less than or equal to VDD.
(2) VDDQ tracks with VDD. AC parameters are measured with VDD and VDDQ tied together.
(3) The AC peak noise on VREF may not allow VREF to deviate from VREF(DC) by more than
1% VDD
(for reference: approx.
15mV)
(4) For reference: approx. VDD/2
15mV
