Description
The PL2732 is a single-chip SuperSpeed USB 3.0 eMMC storage controller with protocol engine that provides USB 3.0 to 8-bit eMMC interface for PCs/tablets/smartphones. When connected to the SuperSpeed USB port of PC, the PL2732 activates its USB BOT Mass Storage Class protocol engine and transfers files at USB 3.0 SuperSpeed (5Gbps that enables the eMMC media up to HS200 performance grade. The PL2732 uses OS built-in USB mass storage drivers so no driver installation is needed for major operating systems like Windows, Mac, Linux, and Android. The PL2732 can be configured as a single LUN USB drive using either one or two storage media. The PL2732 incorporates JBOD capability that provides the flexibility to use two storage media and combine their capacity into one logical drive. To save BOM cost, the PL2732 integrates both SuperSpeed transceiver and Hi-Speed/Full-speed transceiver. It also integrates power management components including eMMC power regulator and other regulators. It also integrates chip power stability monitors to make sure the controller does not enter unknown state when system power is unstable. To maximize system compatibility and to integrate more value-added features, the firmware of PL2732 can also be upgraded via USB interface and stored in the external SPI flash.
