Datasheet

Chapter 8 Configuration Options

8.1Hub

SMSC’s USB 2.0 hub is fully compliant to the Universal Serial Bus Specification available from the USB Implementer’s Forum found at http://www.usb.org (Revision 2.0 April 27, 2000 and the 12/7/2000 and 5/28/2002 Errata). Please reference Chapter 11 (Hub Specification) for general details regarding hub operation and functionality.

For performance reasons, the hub provides 1 transaction translator (TT) that is shared by both downstream ports defined as a single-TT configuration. The TT contains 4 non-periodic buffers.

8.1.1Hub Configuration Options

The SMSC hub supports a large number of features (some are mutually exclusive), and must be configured in order to correctly function when attached to a USB host controller. There are two principal ways to configure the hub:

via the internal default settings or

by settings stored in an external EEPROM or SPI Flash device.

8.1.1.1Power Switching Polarity

The hub will only support active high power controllers.

8.2Card Reader

The SMSC USB4640/USB4640i is fully compliant with the following flash media card reader specifications:

Secure Digital 2.0 / MultiMediaCard 4.2 -SD 2.0, HS-SD, HC-SD

-TransFlash™ and reduced form factor media -1/4/8 bit MMC 4.2

Memory Stick 1.43

Memory Stick Pro Format 1.02

Memory Stick Pro-HG Duo Format 1.01

-Memory Stick, MS Duo, HS-MS, MS Pro-HG, MS Pro

Memory Stick Duo 1.10

xD-Picture Card 1.2

8.3System Configurations

8.3.1EEPROM/SPI Interface

The USB4640/USB4640i can be configured via a 2-wire (I2C) EEPROM (512x8) or an external SPI flash device containing the firmware for the USB4640/USB4640i. If an external configuration device does not exist the internal default values will be used. If one of the external devices is used for configuration, the OEM can update the values through the USB interface. The hub will then “attach” to the upstream USB host.
