This USB 3.0 SD card reader is based upon Universal Serial Bus 3.0 specification, which integrates USB 3.0 & USB 2.0 Transceiver, MCU, SIE regulator and memory card access units into a single chip. It can link in Super Speed, High Speed, or Full Speed operation and support USB 2.0/USB 3.0 power saving mode. Besides, this also supports both the internal MCU program ROM, and external serial flash memory interface. With the external serial flash memory interface, the firmware could be easily updated through USB link. This card reader integrates all regulator, clock generation circuitry and MOSFET components for switching card power, and also dramatically reduce the system cost.
