With our OEM file system modules and chipsets any system can quickly access files on SD and USB storage devices minimal resources -- from off the shelf OEM modules for quick integration to chipsets available to implement right into your own system. Simple commands over UART (serial), SPI, or I2C are used to interact with the file system at speeds reaching up to 4,000,000 bytes per second. These products are capable of accessing two USB storage devices and one memory card simultaneously, support long file names (LFN), and are licensed for commercial use.
The original FAT file system only supported filesnames up to eight characters in length (8.3 format). Our file system solution supports modern Long File Names (LFN) on FAT file systems enabling the use of complete filenames.
ALFAT gives you the option to add a USB 2.0 PHY on one of the USB interfaces. The ALFAT OEM board includes the PHY which can be used as-is or as a starting in your own design since we make its schematic available.
In the SD Reader mode (SDR) the file system chipset still accepts commands to access files on the SD card but it also makes itself appear as an SD card reader through USB, making this an ideal solution for data logging applications.
When introduced in 2003, ALFAT was GHI Electronics’ first and original file system chipset. It supported file system on both SD/MMC and CompactFlash. In 2005, USBwiz was introduced to add support for USB mass storage devices (MSC). The low-cost uALFAT being introduced in 2007. The entire product line was completely reinvented in 2012 with the introduction of the F40 (ALFAT) chipset. The ultra low-cost F20 is the newest offer, announced in 2016. With over ten years of history we're still proud to have one of the most advanced chipsets on the market.
