SCM reader module U disk file reader module

Description: At present, mobile storage devices based on USB interface has been widely used, especially the use of USB-FLASH technology, U disk products almost completely replaced the floppy disk. Use U disk is usually used as an external storage device of the computer, the ability to read and write data directly from the computer to the U disk? The answer is yes. USB118 series U disk embedded reader module provides an easy way to read and write through a serial or parallel port U disk, thus combining the microcontroller serial port or data bus can achieve U disk read and write files. USB118 series U disk is only thumb-sized reader module embedded U disk controller with an integrated USB HOST agreement with a Universal Serial Bus. Mainly used in portable devices or embedded data acquisition system external mass storage. USB118AD with a standard USB port, follow the USB2.0 protocol specification that can fully compatible with all comply with USB2.0 protocol specification removable memory (such as mobile hard disk, U disk and USB interface). Design USB118AD modules adhere to the Xi'an Datai Electronics Co., Ltd USB interface products modular design concept, to provide users with the most streamlined interface, with ultra-small size, low power consumption. USB118A series U disk embedded reader module can be embedded in the user's data collection system in order to achieve mass storage of data. USB118AD module features:? Good compatibility: standard USB HOST interface, compatible with the vast majority of the market, U disk standard communication interfaces:? Using RS232 serial or SPI data interface (USB118AD) concise system protocols:? 14 Compact ? command to complete all read and write process embedded module applications: do not understand the USB protocol, embedded directly into the user's system design ultra-small size:? high density SMT technology, the module size is only thumb-sized USB118 module Dimensions USB118AD functional modules: USB118AD module Performance:????? U disk detection state (such as insert, removed) to create files and directories to open a file and a directory has been created to specify the length of the read data from the file and specify the location to write data to the specified file specified ? address list files and directories directory inquiry delete files and directories follow the USB2.0 standard U disk capacity, offer USB HOST interface standard RS232 serial port: Data format 8 N 1, baud rate 57600bps / 115200bps / 9600bps;???? Applicable USB118A and USB118AD high-speed SPI interface:? 4 control lines for USB118AD file transfer maximum speed:? 150KByte / Sec support file system:? FAT16 / FAT32 Maximum power consumption:? 5V DC power supply, current 100mA (excluding U disk) ? Module dimensions: length x width x height = 52 x 43 x 12mm USB118A application: reasons to use USB118AD: Simple, quick! Can be widely used in the industrial areas, military products, petroleum, transportation, hydrology, medical, railway and other field data acquisition system.
