1.3.3.1 Packaging Decoupling Capacitors
(Ask a Question)PolarFire SoC 0.8 mm and 1.0 mm pitch packages contain decoupling capacitors to support high-speed I/O operation.
Small, low-profile CSP packages (0.5 mm ball pitch, 16 mm × 16 mm, and smaller) do not have package decoupling capacitors.
The following table lists the packaging decoupling capacitors contained in non-CSP packages.
