Electrical Characteristics (continued)
Table 36. Electrical Characteristics (continued)
* On the OR3Txxx devices, the pull-up resistor will externally pull the pin to a level 1.0 V below VDD.
Notes:
The values specified in the table are obtained during a steady-state mode. The transient regimes defined by power switching are not included.
Electrical characteristics for the PCM are advance information.
