68 / 84 page ![]() ST52T410/ST52T420/E420 68/84 11.3 Recommended Operating Condition Operating condition: VDD=5V ±10%; TA=-25/85°C (unless otherwise specified). Notes: 1. The maximum difference between VSS and VSSA, and between VDD and VDDA, must be less than 0.6 V in module. The minimum value of VDDA is 3 V. 2. VDD depend on fOSC , seeFigure11.3 3. The fOSC minallowedtouse theA/D Converter is 2 MHz 4. Lower VDD decreasing fosc (see Figure 11.3). Data illustrated in the figure are characterized but not test- ed.
