PL2731 Datasheet | PROLIFIC

Features 2. General Description - Single-chip Super Speed USB 3.0 Single-LUN Mass Storage Card Reader Controller - pliant with both USB 3.0 and USB 2.0 specification - Integrated Super Speed (5Gbps), Hi-Speed, and Full-speed USB transceiver - High-performance embedded microcontroller - Supports mainstream cost-efficient storage media: Secure Digital TM card (SDSC, SDHC, SDXC, up to v3.01 UHS-I SDR104 and pliant with SD5.0 UHS-II SD card) and Multi Media Card TM (MMC) up to v4.2 - Built-in protocol engine to support USB mass storage class Bulk-Only Transport (BOT) specification. No device driver needed for major operation system. - Firmware can be upgraded via USB interface using either external SPI flash or storage media (to reduce BOM cost). - Built-in clock oscillator, no need of external crystal - Built-in SD card power regulator - Built-in SD interface power regulator - Built-in 5V to 3.3V regulator - QFN32 5mmx5mm package The PL2731 is a Super Speed USB 3.0 Single-LUN card reader controller that integrates high performance protocol engine for USB BOT mass storage class. The PL2731 can support mainstream Secure Digital card up to the highest performance grade of SD3.0 UHS-I SDR104. With Super Speed USB 3.0 transfer rate of 5Gbps, the PL2731 can push the SD card up to UHS-I SDR104 performance. To save BOM cost, many ponents have been integrated into the PL2731. The PL2731 integrates USB 3.0 Super Speed (5Gbps) transceiver and Hi-Speed / Full-speed transceiver. The PL2731 also integrates power management ponents including regulator to SD card power, regulator to SD UHS-I interface, 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 patibility and to integrate more value-added features , the PL2731 can be upgraded through modity SPI flash.
