SMSC USB82640 and USB82660 Combination Hub and Card Reader Devices
SMSC introduced the USB82640 and USB82660 single-chip, 2-port USB 2.0 hub controllers with memory card reader functionality. The new TrueAuto devices enable customers to access navigation data and entertainment content stored directly on solid state memory cards. TrueAuto solutions are designed, fabricated, tested, characterized, qualified, and supported for use in highly reliable automotive applications. Samples of the USB82640 and USB82660 are available today.
The USB82640 provides two downstream USB 2.0 ports plus a single Secure Digital (SD)/MultimediaCard (MMC) or Sony MemoryStick memory card interface. The USB82660 provides a second SD card interface and is capable of operating up to an ambient temperature of 105 degrees Celsius. The second memory card interface enables navigation data and entertainment content to be accessed simultaneously when stored in popular memory card formats.
The SDIO interface can be used to attach modules that provide additional features such as WiFi, Bluetooth, and GPS connections. Car makers can build complex automotive systems with confidence because the quality that the TrueAuto approach delivers ensures that both internal and external connections are highly reliable. Both products are high-performance, low-power, small footprint controller ICs.
USB82640 and USB82660 Additional Features
- PortMap to enable flexible port mapping and port disable sequences so that a single part can be used in multiple platforms that require 2, 3 or 4 USB ports
- PortSwap to ease PCB design by aligning signal traces directly to connectors
- PHYBoost to allow for programmable transceiver drive strength to aid in preserving signal integrity in complex system environments
