    • Standard Enterprise NVMe host control interface
    • Encryption (XTS-AES-256 as defined in the IEEE P1619 specification)
    • Integrated temperature sensing diode. For optimal temperature results, use a remote temperature sensing product that supports resistance cancellation and beta compensation features, such as a Texas Instruments TMP421YZDT
    • Power fault and abrupt shutdown without data loss or corruption
    • Programmable architecture enables SSD developers to control product differentiation through firmware customization
    • Configurable data rate (DDR4 up to DDR4-2133)
    • 16-bit (with embedded ECC) data path with one rank
    • Supports x8 and x16 SDRAM data widths
  • Data integrity and reliability
    • Strong flash ECC
    • Internal data path protection
    • SECDED ECC on all internal RAMs and DDR4 SDRAM
    • End-to-end host to flash data protection
The Flashtec NVMe 2108 controller supports the standard NVM Express (NVMe) host interface, and is optimized for high-performance 4 KB random read/write operations, performing all flash management operations on-chip and consuming negligible host processing and memory resources. Advanced ECC enables current and future architectures with next-generation NAND technologies, and programmable architecture enables SSD product differentiation through firmware customization. Up to 16 GB of DDR4 with 8 Gb components is supported and controllers support the popular 2.5" and M.2 form factors. Flashtec controllers support the industry’s highest mainstream capacity SSD solutions, optimized for enterprise and data center workloads.
