Appendix A Electrical Characteristics
A.1.9 I/O Characteristics
This section describes the characteristics of all 5V I/O pins. All parameters are not always applicable, e.g.
not all pins feature pull up/down resistances.
Table A-6. 5V I/O Characteristics
Conditions are shown in Table A-4 unless otherwise noted
Num C
Rating
1 P Input High Voltage
2 P Input Low Voltage
3 C Input Hysteresis
4 P Input Leakage Current except PU, PV (pins in high
impedance input mode)¹
V_in = V_DD5 or V_SS5
5 P Input Leakage Current PU, PV (pins in high
impedance input mode)²
V_in = V_DD5 or V_SS5
6 P Output High Voltage (pins in output mode, except PU
and PV)
Partial Drive IOH = –1.0mA
Full Drive IOH = –10mA
7 P Output Low Voltage (pins in output mode except PU
and PV)
Partial Drive IOL = +1.0mA
Full Drive IOL = +10mA
8 P Output High Voltage (pins PU and PV in output mode)
IOH = –20mA (typical value at 25°C)
9 P Output Low Voltage (pins PU and PV in output mode)
IOL = +20mA (typical value at 25°C)
10 C Output Rise Time (pins PU and PV in output mode
with slew control enabled) V_DD5=5V, R_load=1KΩ, 10%
to 90% of V_OH
11 C Output Fall Time (pins PU and PV in output mode with
slew control enabled) V_DD5=5V, R_load=1KΩ, 10% to
90% of V_OH
