M3S-TFS-Tiny (hereafter abbreviated TFS) is an original file system which just requires small memory.

We have the various lineup of MCUs, including R8C Family, which are suitable for use in applications such as single-function home appliances and compact industrial equipment, where the incorporation of more sophisticated functionality or the newest technology, with a negligible increase in cost, is desired. To support such development activities, Renesas offers software libraries with only the essential features for application, at low cost.

Use TFS in any device incorporating a target microcontroller for functions such as accumulating measured or archived data, or rewriting a stored program via memory card. Although TFS is an original file system optimized for the target microcontrollers, its wrapping function for FAT file system compatibility and PC data exchange capability enable analysis and management of data by a PC application. Of course, these and other functions can be built in compactly and at low cost.
