I need to know the analog supply current required for AV+ analog input of 8051F02x, since we are providing a supply of 3.3V to this pin.
It depends on which and how many analog peripherals are active.
The analog supply current is 1.7 mA typical for AV+ = 2.7V, Internal REF, ADC, DAC and Comparators all active (per datasheet table 1.1). Since we do not have a specification for AV+ = 3.3V, I would use the above specification as guidance on the magnitude.
Furthermore, the analog supply current with all analog sub-systems inactive is 0.2 mA typical (per datasheet table 1.1).
