NOTES:
1. Parameters are valid over specified temperature range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4V and 3.0V with a transition time of 5 ns
maximum. For X1/CLK this swing is between 0.4V and 4.4V. All time measurements are referenced at input voltages of 0.8V and 2.0V and
output voltages of 0.8V and 2.0V, as appropriate.
3. Typical values are at +25 C, typical supply voltages, and typical processing parameters.
4. Test conditions for outputs: C
L
= 150 pF, except interrupt outputs. Test conditions for interrupt outputs: C
L
= 50 pF, R
L
= 2.7K ohm to V
CC
.
5. Input port pins have active pull up transistors that will source a typical 2
μ
A from Vcc when the input pins are at Vss. Input port pins at V
CC
source 0.0
μ

6. All outputs are disconnected. Inputs are switching between CMOS levels of V
CC
–0.2V and V
SS
+ 0.2V.
7. See UART application note for power down currents of 10 ua or less.
