DAE-3 And DAE-3HT Differences
The DAE-3 device family includes both the DAE-3 and DAE-3HT.
Functional specifications are identical to both designations of
this family. However, the DAE-3HT, provided in its smaller 72-pin
package supports system and assignable functions that are
mapped to the pins supported in that package. Complete pin
functions of all pins of both devices of the DAE-3 family are listed
in the Pin Description Tables.
Pin Function Mapping Between Devices
Table 3 lists the pin numbers, names and functions for both the
DAE-3 and DAE-3HT devices, and provides a mapping of the pin
functions between those devices.
