F 3 - FLASH MEMORY CONTROLLER
F3 - Flash Memory Controller
The Hyperstone F3 family of Flash Memory Controllers together with provided application and flash specific firmware offers an easy-to-use turnkey platform for high endurance flash disks of various form factors and interface standards.  
  • Patented superior wear leveling together with ECC ensuring highest reliability and endurance
  • Optimized 32 Bit RISC core, instruction set and firmware for flash handling
  • Dual channel Direct Flash Access unit (DFA) including sector buffers for interleaved operations
  • Most power efficient design together with additional power saving features
  • Smart and custom features possible by simple firmware upgrades
  • ASSP with no need for external voltage regulator, detector or diodes, only few capacitors or resistors need to be added to bill of materials
  • Turnkey solution including firmware, manufacturing kit, test and development hardware, and reference schematics for a CF card or 2.5” solid state disk, and testmetrix log files
