#38469 - RE: How much and an AT89c52 sink/source? Responding to: ???'s previous message |
It IS in the datasheet (http://www.atmel.com/dyn/resou...c0313.pdf). Anyway, for P1 it reads:
Iol per pin : max. 10 mA Iol per port : max. 15 mA Iol all ports: max. 71 mA As you can see, the ports are only good to sink, not to source. Use additional pull-ups if needed. |
