Hyperstone F2 Flash Memory Controller

F2 - CompactFlash (CF) Card & Solid State Disk (SSD) Controller

Our F2 family of flash memory controllers, the most reliable platform, has been in the market since many years and has been used within several million solutions. Targeting CF cards, Solid State Disks (SSD,) and on-board integration of embedded Flash Disk solutions, F2 offers highest power efficiency, compatibility to flash memories and host systems and is available in consumer and industrial grades.

  • Integrated on-chip components decrease cost and risk related to bill of material management
  • In-field reprogrammable firmware for leading compatibility and feature upgrades
  • 32-Bit RISC core increases ability to use software based features
  • Power-down modes for highest power efficiency
  • Patented ECC and wear-leveling features
  • Sophisticated design preventing data corruption in case of any unexpected power down
