NOTES:
1. Parameters are valid over specified temperature range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4 V and 2.4 V with a transition time of
5 ns maximum. For X1/CLK this swing is between 0.4 V and 4.4 V. 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.
3. Typical values are at +25
°C, typical supply voltages, and typical processing parameters.
4. Test conditions for outputs: CL = 150 pF, except interrupt outputs. Test condition for interrupt outputs: CL = 50 pF, RL = 2.7 k to VCC.
5. All outputs are disconnected. Inputs are switching between TTL levels of 2.4 V and 0.4 V or CMOS levels of VCC – 0.2 V and VSS + 0.2 V.
6. Tamb ≥ 0 °C
7. Tamb < 0 °C
8. See UART application note for power-down currents less than 5
