Description

The USB82640/60 is designed for applications that demand low power and a small footprint without compromising performance. Offering a high level of interoperability, the USB82640/60 allows system designers the flexibility of independent access to a wide selection of flash media and additional downstream USB access ports.

The USB82640/60 consists of USB 2.0 device transceivers with 2-port hub functionality, a fast 8051 micro-processor with Secure Digital/Memory Stick interfaces in a single, fully-integrated chip. It offers USB expansion as well as a flash media read/write interface capable of ultrahigh-performance operation. Various programmable features, including SMSC's unique PortMap, PortSwap and PHYBoost, are designed to aid system designers in simplifying PCB layout and optimizing bill-of-material cost.

The USB82660 has been specifically designed to support operation at temperatures up to +105 °C.

SMSC automotive grade devices are designed, fabricated,tested, characterized, qualified, and supported specifically for use in automotive applications. TrueAuto robust-ness begins with proprietary design for reliability techniques within the silicon IC itself and in the design of the package.

TrueAuto qualified technologies and processes are used to fabricate the products with enhanced monitors to continuously drive improvements in accordance with our zero dpm goals.

Product qualification is focused on the most demanding customer expectations and exceeds many of the automotive reliability standards including AEC-Q100.

SMSC TrueAuto services are provided by a dedicated organization composed of sales, marketing, applications engineering, operations, quality, and product support personnel specialized in meeting the requirements of the automotive customer.

Hub and Flash Media Card Controller Combo	Cost-effective, small-footprint solution integrates two functions into a single chip
Ultra Fast Flash Memory Access	Up to 35 MB/s data transfer rates
External and Internal ROM	Flexible programming for software architecture and enhanced overall system performance
	Flexible port mapping and disable sequences support multiple platform designs.
	Adds per-port programmability to USB differential-pair pin locations. PortSwap allows direct alignment of USB signals (D+/D-) to connectors avoiding uneven trace length or crossing of the USB differential signals on the PCB.
	Enables programmable four-level USB signal drive strengths in downstream port transceivers. PHYBoost attempts to restore USB signal integrity.
