PIO Controller Lines
I/O Lines Current Drawing
AT91SAM7X512/256/128 Preliminary
All the I/O lines, PA0 to PA30 and PB0 to PB30, are 5V-tolerant and all integrate a programma-
ble pull-up resistor. Programming of this pull-up resistor is performed independently for each I/O
line through the PIO controllers.
5V-tolerant means that the I/O lines can drive voltage level according to VDDIO, but can be
driven with a voltage of up to 5.5V. However, driving an I/O line with a voltage over VDDIO while
the programmable pull-up resistor is enabled will create a current path through the pull-up resis-
tor from the I/O line to VDDIO. Care should be taken, in particular at reset, as all the I/O lines
default to input with pull-up resistor enabled at reset.
The PIO lines PA0 to PA3 are high-drive current capable. Each of these I/O lines can drive up to
16 mA permanently.
The remaining I/O lines can draw only 8 mA.
However, the total current drawn by all the I/O lines cannot exceed 200 mA.
