3.3 V/5.0 V Dual Universal Asynchronous Receiver/Transmitter
[1]
The following conditions apply:
a) Parameters are valid over specied temperature and voltage range.
b) All voltage measurements are referenced to ground. For testing, all inputs swing between 0.4 V and 3.0 V with a transition time of
5 ns maximum. For X1/CLK this swing is between 0.4 V and 0.8VCC. All time measurements are referenced at input voltages of 0.8 V
and 2.0 V, and output voltages of 0.8 V and 2.0 V, as appropriate.
c) Typical values are at 25
°C, typical supply voltages, and typical processing parameters.
[2]
Test conditions for outputs: CL = 125 pF, except interrupt outputs. Test conditions for interrupt outputs: CL = 125 pF,
constant current source = 2.6 mA.
[3]
Input port pins have active pull-up transistors that will source a typical 2
A from V
CC when they are at VSS. Input port pins at VCC source
0.0
A.
[4]
All outputs are disconnected. Inputs are switching between CMOS levels of VCC 0.2 V and VSS + 0.2 V.
Table 66.
Static characteristics, 3.3 V operation[1]
VCC = 3.3 V ± 10 %; Tamb = 40 °Cto+85 °C; unless otherwise specied.
