[1]

Typical ratings are not guaranteed. The values listed are at room temperature, 3 V.

[2]

Ports in quasi-bidirectional mode with weak pull-up (applies to all port pins with pull-ups)

[3]

Port pins source a transition current when used in quasi-bidirectional mode and externally driven from ‘1’ to ‘0’. This current is highest

when VIN is approximately 2 V.

[4]

Measured with port in high-impedance mode.

[5]

Measured with port in quasi-bidirectional mode.

[6]

Pin capacitance is characterized but not tested.

[7]

The IDD, IPD speciﬁcations are measured using an external clock with the following functions disabled: comparators, brownout detect,

and Watchdog timer (P89LPC901).

[8]

The IDD, IPD speciﬁcations are measured with the following functions disabled: comparators, brownout detect, and Watchdog timer

(P89LPC902, P89LPC903).
