Ok, so we fudged the title but it got your attention and now that we have your attention we want to take a minute and talk about our latest file system solution, the F20 System on Chip (SoC) and F20-uSD OEM module. The F20 System on Chip (SoC) is a small, low-cost and low-power file system solution that provides access to files and folders on an SD card using simple serial commands (did we mention that it was really cheap at $4.80 in volume!). The F20-uSD module is an OEM module designed for taking the F20 SoC out for a test drive.
The F20 SoC (AKA ReallyTinyFAT) is the younger, smaller brother of the ALFAT System on Chip. The F20 SoC does not require an external crystal instead an internal clock is used. The commands supported are a subset of the commands supported by the ALFAT SoC, for more information including a comparsion table please take a look at the F20 Developers’ Guide. The F20 SoC is currently not available as we are using the the F20-uSD OEM module to launch the F20 family of products.
