Simplify Control logic, security and, power and thermal Management

First-On, Last-Off Solutions for Main Boards – Non-volatile, instant-on, lowest cost per I/IO, feature-rich MachXO3 FPGA family offers a wide range of single, dual, quadruple and 8-Socket CPU boards for Server, Storage and networking systems.

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.

Reduce telemetry and CPLD cost, Routing Congestion and BOM – Integrate 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.
