feature set and differ only in physical pinout. They are based on the Microchip SAM D21 family. The PD69210 or PD69220 controllers are remended for all new designs.
The PD69210 or PD69220 controllers when paired with the Microchip PD69208T4, PD69204T4, or PD69208M managers are part of a Power over Ethernet Power Supplying Equipment (PSE) system. This system enables designers to integrate enhanced mode Po E capabilities, as specified in IEEE® 802.3af, IEEE 802.3at, IEEE 802.3bt, and Po H standards, into an Ethernet switch. They support up to 48 4-pair or 2-pair logical ports.
Both controllers are available in a 32-pin, 5 mm × 5 mm QFN package.
