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:

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
