Data Center Systems – Storage Systems

Reusable low-cost control PLD solution for reduced time-to-market

Reliable Startup Control in Storage System Boards – Non-volatile, instant-on, lowest cost per I/IO, feature-rich MachXO3 FPGA family enables integration of first-on/last-off functions in a storage controller board based on Intel or ARM processors.

Eliminate Data Loss Due to Power Fail – Power failure early warning through precision voltage monitoring; integrated voltage, current and temperature monitoring, and measurement functions of hardware management logic using L-ASC10. In addition the real time fault logging capability simplifies hardware debug.

Small Form-Factor, Low-Cost Options for Hot-Swappable Backplane Applications – MachXO2 products available in TQFP and QFN packages provide lowest cost to manufacture options for auto-configure HDD, SSD and NVMe drives.
