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/O, feature-rich MachXO3 FPGA family offers a wide range of single, dual, quadruple and 8-socket CPU boards for server, storage and networking systems. MachXO2/3 devices are the first devices to power-on the board and orchestrate the power delivery to all devices. These devices also integrate multiple control busses on the board such as SPI, I2C, SGPIO and reduce the number of pins needed on PCH and BMC.

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. Real-time fault logging capability simplifies hardware debug.

Small Form-Factor, Low-Cost Options for Integrating I2C Buffers, Glue Logic and Level Translators – MachXO2 products, available in TQFP and QFN packages, provide the lowest-cost-to-manufacture options for auto-configure HDD, SSD and NVMe drives in hot swappable appliance backplanes. These devices also reduce the number of pins on the connector, while simplifying the interface to monitor and control drives on the backplane. MachXO2 QFN packages integrate level translating I2C buffers between CPU and DDR memories, as well as GTL transceivers.
