SP40 targets low to high volume digital ASIC products in the Military and Aerospace, Industrial, Networking & Telecommunications, Computing and Consumer markets. The high performance capabilities of the process make SP40 ideal for high speed applications including high performance ARM processor, Memory interface, Communication interface and Analog cells. Combined with support for a rich family of IP, SP40 supports applications in military munitions, radar systems, avionics, secure communications, wireless infrastructure, industrial controls, printers and infotainment. The ON Semiconductor RTL signoff, netlist hand-off and optional Spec handoff flows provide quick and seamless access for SP40 designs.

Targeted Quality Standards
SP40 offers manufacturing options that includes ITAR and DO-254 support and meets the specific quality standards needed to support military and aerospace applications.

Second Source for Existing Products
The ASIC-to-ASIC conversion capability from ON Semiconductor allows SP40 to be a cost-effective alternative supply for existing high-volume products.

FPGA Prototype Designs
Based on the extensive experience of ON Semiconductor with FPGA conversions, ASIC designs prototyped in FPGAs, or those which are partially prototyped or partitioned between FPGAs and other devices such as DDR, SerDes, or USB interfaces can be integrated into a single SP40 device.

ON Semiconductor can also provide customers with a comprehensive library of soft IP that can be prototyped in an FPGA, further easing the process of getting to a cost competitive, low power ASIC for production.

FPGA Conversion
The SP40 product roadmap will be expanded to offer support for 0.9~1.1 V FPGA devices, including:

  • Full I/O
  • Memory feature compatibility
  • DLL/PLL equivalence
  • System IP enablement
