This section outlines major differences in characteristics that may have an effect on
the application in which the device is used. For detailed information, refer to the most
recent version of the device datasheets.
Active and Idle mode current consumption of the device has been reduced
significantly. The tables below present typical current consumption figures at room
temperature. All values are taken from device datasheets, unless otherwise noted.
Table 2-1. Typical Current Consumption of Device at Room Temperature
In Table 2-2 are listed differences in output voltage levels.
Table 2-2. Changes to VOL and VOH Levels
In Table 2-3 are listed differences in reference voltage levels.
Table 2-3. Changes to Internal Voltage Reference Levels
