5V — 0 — 1.5 V Input Low Voltage for I/O Ports or IL Input Pins V — — 0 — 0.2VDD 5V — 3.5 — 5 V Input High Voltage for I/O Ports IH or Input Pins V — — 0.8VDD — VDD 3V 5 10 — IOL Sink Current for I/O Pins VOL=0.1VDD mA 5V 10 20 — 3V -1.25 -2.5 — IOH Source Current for I/O Pins VOH=0.9VDD mA 5V -2.5 -5 — 3V 20 60 100 LVPU=0 5V 10 30 50 R Pull-high Resistance for I/O PH Ports(Note) kΩ 3V 6.67 15 23 LVPU=1 5V 3.5 7.5 12 ILEAK Input Leakage Current 5V VIN=VDD or VIN=VSS — — ±1 μA Note: The RPH internal pull high resistance value is calculated by connecting to ground and enabled input pin with pull-high resistor and then measuring the input sink current at the specified supply voltage level. Dividing the voltage by this measured current provides the RPH value.
