USB 3.0 Card Reader Controller

The Realtek RTS5307 USB3.0 Card Reader controller is based upon Universal Serial Bus 3.0 Specification,
which integrates USB 3.0 and USB2.0 Transceivers, MCU, SIE, regulators and memory card access units
into a single chip. It can be linked in Super Speed, High Speed or Full Speed operation and supports
USB2.0/USB3.0 power saving mode. It provides 1LUN or 2LUNs (Logic Unit Number) that can support
Memory Stick TM, Memory Stick Pro TM, Memory Stick PRO-HG Duo TM, Secure Digital TM and MultiMedia Card
The Realtek USB3.0 Card Reader supports both the internal MCU program ROM and external Serial Flash
interface. With the external Serial flash interface, the control firmware could be easily re-configured through
USB link. This could ease the software developing works and squeeze the prototyping schedule.
The Realtek RTS5307 USB3.0 Card Reader integrates all regulators, clock generation circuitry and
MOSFET components for switching card power, and could dramatically reduce the system BOM cost.
