... WE signals are sampled on the clock edge that samples ADSC low (and ADSP high). • Master chip enable CE0 blocks ADSP, but not ADSC. The AS7C33128FT18B family operates from a core 3.3V power supply. I/Os use a separate power supply that can operate at 2.5V or 3.3V. These devices are available in a 100-pin TQFP package. ...
