USB4640/USB4640i

High Speed Inter-Chip (HSIC)

USB 2.0 Hub and Flash Media

Controller

PRODUCT FEATURES

General Description

The SMSC USB4640/USB4640i is a Hi-Speed HSIC USB hub

and card reader combo solution with an upstream port

compliant to HSIC 1.0, a supplement to the USB 2.0

specification. The two downstream ports are compliant with the

USB 2.0 specification.

High Speed Inter-Chip (HSIC) is a digital interconnect bus that

enables the use of USB technology as a low-power chip-to-chip

interconnect at speeds up to 480 Mb/s. The HSIC interface is

an industry standard 2-pin digital interface which uses standard

USB software. The SMSC USB4640/USB4640i provides an

ultra fast interface between an HSIC enabled host and today’s

popular flash media formats. The controller allows read/write

capability to flash media from the following families:

–

Secure Digital

(SD)

MultiMediaCard

(MMC)

Memory Stick

(MS)

xD Picture Card

(xD)

Features

Compliance with the following flash media card

specifications SD 2.0 / MMC 4.2 / MS 1.43 / MS-Pro 1.02 /

MS-Pro-HG 1.01 / MS-Duo 1.10 / xD 1.2

Low-power digital HSIC interface offers a replacement for

onboard host and device connection for analog USB bus

cable

HSIC interface enables printers, mobile PCs, ultra-mobile

PCs, and cell phone products to reduce the total power

budget while taking full advantage of USB connectivity and

compatibility with existing USB drivers and software

External 1.2 V reference allows upstream and downstream

HSIC links to use the same voltage reference

Supports a single external 3.3 V supply source; internal

regulators provide 1.8 V internal core voltage for additional

bill of materials and power savings

The transaction translator (TT) in the hub supports operation

of Full-Speed and Low-Speed peripherals

9 K RAM | 64 K on-chip ROM

Enhanced EMI rejection and ESD protection performance

Hub and flash media reader/writer configuration from a

single source: External I

ROM or external SPI ROM

— Configures internal code using an external I

C EEPROM

— Supports external code using an SPI Flash EEPROM

— Customizable vendor ID, product ID, and language ID if using

an external EEPROM

Datasheet

The USB4640/USB4640i offers a versatile, cost-effective, and

energy-efficient hub controller with 2 downstream USB 2.0

ports. This combo solution leverages SMSC’s innovative

technology that delivers industry-leading data throughput in

mixed-speed USB environments. Average sustained transfer

rates exceeding 35 MB/s are possible

Highlights

Upstream HSIC port and 2 exposed Hi-Speed USB 2.0

downstream ports for external peripheral expansion

The dedicated flash media reader is internally attached to a

3rd downstream port of the hub as a USB Compound

Device

— a single or multiplexed flash media reader interface

PortMap

— Flexible port mapping and port disable sequencing supports

multiple platform designs

Up to 9 configurable GPIOs for special functions

The USB4640 supports the commercial temperature range

of 0°C to +70°C

The USB4640i supports the industrial temperature range of

-40°C to +85°C

48-pin QFN lead-free, RoHS compliant package (7x7 mm)

Applications

3G/4G handsets, smartphones, cell phones, and other

mobile devices

Desktop and mobile PCs

Printers

GPS navigation systems

Media players/viewers

Consumer A/V

Set-top boxes

Industrial products

Revision 1.0 (06-09-09)

PortSwap

— Programmable USB differential-pair pin locations eases PCB

design by aligning USB signal traces directly to connectors

PHYBoost

— Programmable USB transceiver drive strength recovers signal

integrity
