Hi all, where I can find what’s the sink/source current for each I/O pin and what’s the combined total current?
Looks like something else I forgot to put in docs – don’t tell Gus!
Each I/O pin can sink or source up to +/- 8 mA, and up to +/- 20 mA with relaxed I/O output voltage ratings. For example, the maximum output low voltage is 0.4 volts when I/O current is +8 mA, but could be as high as 1.3 volts when the I/O current is +20 mA. The minimum output high voltage is Vdd - 0.4 volts when the I/O current is -8 mA, but could be as low as Vdd - 1.3 volts when the I/O current is -20 mA.
The total output current sunk or sourced by the sum of all I/Os and control pins must not exceed 140 mA.
Thanks a lot
