Micro memory cards have already been widely applied in a variety of electronic products. Due to its compact and portable size in addition to its high capacity, high speed, and expandability, memory cards allow users to conveniently store and transfer data. Almost all digital cameras, mobile phones, and all types of embedded-system devices are starting to use memory cards as the major or expand data storage media.

 

The newly released CSC3700/CSC3710 USB OTG controller chip from Chesen Electronics Corp (CEC) contains a dual memory card controller supporting SD/SDHC/MMC/MS-Pro/MS-Pro Duo/M2 memory cards or iNAND and eMMC built-in memory. The brand new hardware architecture allows billion-pixel photos or MP3 songs high speed data transfer between two memory cards within seconds. The controller also can access data in USB memory devices through the USB OTG interfaces or acts as PC dual card reader peripheral by connecting with the computer. Design support is given by providing free sample source code and a function-driven library toolbox. It can substantially reduce the design cycles and labor costs of the USB and card driver’s development process. Currently the CSC3700/CSC3710 is available now for providing trial sample and the development platform OXDK3700. Further version with AES data encryption and decryption will be pin to pin compatible and plan to release by the fourth quarter of this year.
