77 / 140 page  Document Number: 001-84932 Rev. *N Page 76 of 139 PSoC® 5LP: CY8C58LP Family Datasheet 11.4 Inputs and Outputs Specifications are valid for –40 °C ≤ TA ≤ 105 °C and TJ ≤ 120 °C, except where noted. Specifications are valid for 1.71 V to 5.5 V, except where noted. Unless otherwise specified, all charts and graphs show typical values. When the power supplies ramp up, the pin voltages are indeterminate until both VDDIO and VDDA reach the IPOR voltage, which can be as high as 1.45 V. At that point, the pins change to their normal NVL settings. 11.4.1 GPIO Table 11-8.
