Xi'an SYNC

Product overview

SYN921 The USB type read and write module is an ultra-high cost performance U disk read and write module developed by Xi'an synchronous Electronic Technology Co., Ltd.At present, mobile storage devices based on USB2.0 interface have been widely used, especially the U disk with USB-FLASH Technology (including flash disk, USB flash disk, USB mobile hard disk, etc.), has become a very common mobile storage device, U disk is easier to purchase and carry than flash memory, and the capacity of the product has increased from 16M a few years ago to the current 128G, with a variety of capacity options.Many SCM systems require memory, so the single chip microcomputer system can directly use U disk as a large capacity mobile memory, and is convenient to exchange data with WINDOWS operating system. It is mainly used for external storage of portable instruments or embedded data acquisition systems.

USB The read and write module is used to provide an interface for reading and writing file data in U disk to the embedded system / SCM system. Basically, it does not need to occupy too much storage space of SCM system, and supports commonly used USB storage devices (including U disk, /USB hard disk, /USB flash disk, /USB card reader).

Key word MCU read and write U disk, U disk read and write module, MCU U disk, microcontroller serial port to write U disk.

Product function

1)   Support SPI interface or asynchronous serial port, microcontroller /DSP/MCU/MPU and other controllers can access any files in U disk by controlling any of the above communication interfaces.

2)   With standard USB2.0 interface, following the USB2.0 protocol specification, using more than 10 simplified commands to complete all reading and writing processes, including: self checking of USB devices, opening, building or deleting files, creating subdirectories, reading and writing files, querying physical capacity, querying remaining space, etc., users do not need to understand USB protocol, directly embedded in the user system, and can fully comply with all mobile memory that comply with USB protocol specification (such as U disk and USB interface mobile hard disk, etc.).

3)   You can create TXT, binary, Word, Excel and other types of files.

Product characteristics

A)   High cost performance and wide application.

B)   Strong compatibility, high reliability and easy installation.

C)   Low power consumption, small volume, economical and practical.

Typical application

1)   USB The read and write module is used to provide an interface for reading and writing file data in U disk to the embedded system / SCM system. Basically, it does not need to occupy too much storage space of SCM system, and supports commonly used USB storage devices (including U disk, /USB hard disk, /USB flash disk, /USB card reader).
