Unused Pins
Table TBD shows how to connect the devices unused
pins when circuit blocks are disabled. If the system is
extremely noisy or there is a concern that unused analog
inputs might be enabled, then alternatively unused analog
audio inputs can be AC coupled to AGND (if component
cost and area allow it).
WLP Applications Information
For the latest application details on WLP construction,
dimensions, tape carrier information, PCB techniques,
bump-pad layout, and recommended reflow temperature
profile, as well as the latest information on reliability test-
ing results, refer to the Application Note 1891: Wafer-
Level Packaging (WLP) and Its Applications. Figure 58
shows the dimensions of the WLP balls used on this
device.
