VDDQ I/O power supply current consumption of part CY7C2663KV18-450BZI is required

[TuDo_3177296]

Hello,

I could not find the VDDQ supply power consumption in datasheet. Could you provide a maximum current consumption of VDDQ  of part CY7C2663KV18-450BZI ?

Also you could provide that if Vref (0.75V) draw current or not  ?

Regards,

Hi Doner,

Please refer to the Application note below. It has an "online tool for calculating the Junction temperature" on page 5 of the app note. You can use the online calculator to calculate the supply power consumption. It also has example for QDR II+ devices so you can refer to that and calculate the values as per your case.

Vref pin will consume current. The value will depend on the loading that is observed by the Vref pin.
