PIO Controller lines
I/O Lines Current Drawing
AT91SAM7SE512/256/32 [Advance Information Summary]
All the I/O lines PA0 to PA31, PB0 to PB31, PC0 to PC23 integrate a programmable pull-up
resistor. Programming of this pull-up resistor is performed independently for each I/O line
through the PIO controllers.
Typical pull-up value is 100 kΩ.
All the I/O lines have schmitt trigger inputs.
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 300 mA.
