Maxim Integrated Products has announced a reference design to protect Xilinx Spartan 6 field programmable gate arrays (FPGAs). This reference design comprises free security software from Maxim or Xilinx and the Maxim's single wire secure memory device DS28E01-100.
According to ABIresearch, the counterfeit goods constitutes to 5-7% of world trade. This reference design tackles counterfeiters by preventing unauthorized product builds and safeguarding FPGA IP. The DS28E01-100 operates over a single pin and has a built-in challenge and response SHA-1 authentication scheme.
The reference design allows manufacturers to remotely turn on fee based software controlled feature upgrades. The security scheme requires secret keys to be loaded in the FPGA and the 1-wire secure memory. Maxim's reference core overlays on the Spartan-6 device and utilizes less than 5% of the logic cell resources.
"Maxim's security system provides best-in-class protection for licensing control and feature-set upgrades. If the DS28E01-100 and the FPGA do not 'recognize' each other, the FPGA design is effectively disabled," said Prem Nayar, business manager for secure information & authentication products at Maxim Integrated Products.
"With the use of a Maxim DS28E01-100 1-wire secure memory device, Xilinx customers can easily add a level of design security to their products. While targeting the Xilinx Spartan-6 families today, this could also be used with Artix-7, Kintex-7, Virtex-7 and the Zynq-7000 families," said Jim Burnham, platform marketing for Zynq, Virtex-4,-5,-6, Spartan and CPLD development boards and kits at Xilinx.
The DS28E01-100 reads and writes over a 2.8V to 5.25V voltage range and operates at -40°C to +85°C.
The reference security scheme (Xilinx XAPP780) for the Spartan-6 family is evaluation ready. Pricing for DS28E01 begins at $0.84 (1000-up, FOB USA).
