USB4640/USB4640i High-Speed Inter-Chip (HSIC) USB 2.0 Hub and Flash Media Controller PRODUCT FEATURES Datasheet General Description Features Compliance with the following flash media card The SMSC USB4640/USB4640i is a Hi-Speed HSIC USB specifications SD 2.0 MMC 4.2 MS 1.43 MS-Pro 1.02 hub and card reader combo solution with an upstream port MS-Pro-HG 1.01 MS-Duo 1.10 and xD 1.2 that is compliant to HSIC 1.0 (supplement to the USB 2.0 Low-power digital HSIC interface offers a replacement for Specification). The two downstream ports are compliant with onboard host and device connection for analog USB bus the USB 2.0 Specification. cable HSIC interface enables printers, mobile PCs, ultra-mobile High-Speed Inter-Chip (HSIC) is a digital interconnect bus PCs, and cell phone products to reduce the total power that enables the use of USB technology as a low-power chip- budget to-chip interconnect at speeds up to 480 Mb/s. The HSIC HSIC interface provides use of USB connectivity and interface is an industry standard 2-pin digital interface which compatibility with existing USB drivers and software uses standard USB software. The USB4640/USB4640i External 1.2 V reference allows upstream/downstream provides an ultra fast interface between an HSIC enabled HSIC links to use the same voltage reference host and several popular flash media formats. The controller Supports a single external 3.3 V supply source internal allows read/write capability to flash media from the following regulators provide 1.8 V internal core voltage for additional families: TM Secure Digital (SD) bill of materials and power savings TM MultiMediaCard (MMC) The hub transaction translator (TT) supports Full-Speed Memory Stick (MS) and Low-Speed peripheral operation TM 1 xD-Picture Card (xD) 9 KB RAM 64 KB on-chip ROM Enhanced EMI rejection and ESD protection performance The USB4640/USB4640i combo solution leverages SMSCs innovative technology that delivers industry-leading data Hub and flash media reader/writer configuration from a throughput in mixed-speed USB environments. Average single source: 2 2 Configures internal code using an external I C EEPROM sustained transfer rates exceeding 35 MB/s are possible .
