8-bit microcontrollers with accelerated two-clock 80C51 core
[1] Typical ratings are not guaranteed. The values listed are at room temperature, 3 V.
[2] The I
DD(oper)
,I
DD(idle)
, and I
DD(pd)
specifications are measured using an external clock with the following functions disabled: comparators,
real-time clock, and watchdog timer.
[3] The I
DD(tpd)
specification is measured using an external clock with the following functions disabled: comparators, real-time clock,
brownout detect, and watchdog timer.

exceed the related specification.
[5] This specification can be applied to pins which have A/D input or analog comparator input functions when the pin is not being used for
those analog functions. When the pin is being used as an analog input pin, the maximum voltage on the pin must be limited to 4.0 V with
respect to V
SS
.
[6] Pin capacitance is characterized but not tested.
[7] Measured with port in quasi-bidirectional mode.
[8] Measured with port in high-impedance mode.
[9] 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 V
I
is approximately 2 V.
