Silicon: CD17B10
The DOSonCHIP™ CD17B10 is a microSDHC/microSD/miniSDHC/miniSD/SDHC/SD/MMC card controller with an integrated PC compatible file system. This chip offers the lowest cost, lowest power, and smallest footprint solution, enabling a wide range of applications. Containing a complete FAT file system stack and media card physical interface, this all-in-one chip enables quick design-in to add removable mass data storage to your product.
In addition, the CD17B10 can make your existing products more powerful without needing to add the complexity of an OS. Using simple, straight-forward commands, large databases and/or media files can be easily accessed as well as long-term data logging and in-the-field firmware updates—all utilizing PC compatible files.
