FACTORY TRIMMING AND CALIBRATION
To enhance the ease-of-use of the 908E626, various
parameters (e.g. ICG trim value) are stored in the flash memory
of the device. The following flash memory locations are
reserved for this purpose and might have a value different from
the “empty” (0xFF) state:
0xFD80:0xFDDF Trim and Calibration Values
0xFFFE:0xFFFF Reset Vector
In the event the application uses these parameters, one has
to take care not to erase or override these values. If these
parameters are not used, these flash locations can be erased
and otherwise used.
PACKAGE THERMAL PERFORMANCE
Figure 13
shows a thermal response curve for a package
mounted onto a thermally enhanced PCB.
Note
The PCB board is a multi-layer board with two inner
copper planes (2s2p). The board conforms to JEDEC EIA/
JESD 51-5 and JESD51-7. Substrate thickness is 1.60 mm.
Top and bottom copper trace layers are 0.7 mm thick, with two
inner copper planes of 0.35 mm thickness. Thermal vias have
0.35 mm thick plating.
