>>"Do the dedicated peripherals in the 5LP's use UDB blocks?"
--> No. The dedicated blocks are separate hardware IPs present in the PSoC5Lp which can be configured as well as accessed through registers.
>>"When you place a peripheral in your schematic, can you tell in advance (before compile) if it's dedicated or UDB?"
--> Yes. If the peripheral placed by you is present in the resource meter tab of the PSoC Creator (present at the right side of PSoC Creator GUI) then it is dedicated. Also, you can see the percentage of UDBs consumed in the same resource meter tab.
--> You can also see the resourses consumed in .rpt document in the Results section of PSoC Creator.
Please note that you have to build the project in order to see the changes in the Resource meter GUI. For more information on fixed function/dedicated peripherals inside the device, please refer the Datasheet as well as Architecture TRM.
Hope this helps !
