P89LPC912/913/914

8-bit microcontrollers with two-clock 80C51 core

[1]

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

[2]

The IDD(oper),IDD(idle) and IDD(pd) speciﬁcations are measured using an external clock with the following functions disabled: comparators,

brownout detect, and watchdog timer (P89LPC912, P89LPC913).

[3]

The IDD(oper), IDD(idle) and IDD(pd) speciﬁcations are measured with the following functions disabled: comparators, brownout detect, and

watchdog timer (P89LPC914).

[4]

Pin capacitance is characterized but not tested.

[5]

Measured with port in quasi-bidirectional mode.

[6]

Measured with port in high-impedance mode.

[7]

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

[8]

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

highest when VI is approximately 2 V.
