Description
| The PL2731is a SuperSpeedUSB 3.0Single-LUNcard readercontrollerthat integrateshigh performance protocol engine forUSB BOT mass storage class. The PL2731 can support mainstream Secure Digital card up to thehighest performance grade of SD3.0 UHS-I SDR104. With SuperSpeed USB3.0 transfer rate of 5Gbps, the PL2731 can push the SD card up to UHS-I SDR104 performance.
To save BOM cost, many components have been integrated into the PL2731. The PL2731integrates USB 3.0 SuperSpeed (5Gbps) transceiver and Hi-Speed / Full-speed transceiver. The PL2731 also integrates power management components including regulator to SD card power, regulatorto SD UHS-Iinterface, and regulator for GPIO. Besides built-in regulators, the PL2731 integrates chip power stability monitors to make sure controller does not enter unknown state when system power is unstable. To maximize system compatibility and to integrate more value-added features, the PL2731 can be upgraded through commodity SPI flash. |
