Product Details

The DS28E01PMOD provides the necessary hardware to interface a DS28E01-100 1Kb protected 1-Wire® EEPROM with a SHA-1 engine to a Xilinx Spartan®-6 LX16 Evaluation Kit made by Avnet. By using the DS28E01PMOD and the PicoBlaze™ SHA-1 Authentication Design for the Xilinx Spartan-6 LX16 Evaluation Kit, a secure SHA-1 challenge-and-response authentication can be implemented. The PicoBlaze SHA-1 Authentication Design is based upon the Xilinx XAPP780 application note, FPGA IFF Copy Protection Using Dallas Semiconductor/Maxim DS2432 Secure EEPROMs.

Product Details

The secure authentication starter kit is a highly programmable hardware/software system for development, lab testing, and demonstration of embedded applications that use Maxim's SHA-1-based secure authentication products. The system supports multiple options for demonstrating and developing both host SHA-1 computation and associated host communication with Maxim's 1-Wire® and I²C-based SHA-1 slave ICs. Multiple options are supported for host SHA-1 computation development including fixed function processing with the Maxim DS2460, microcontroller(FC)-based with a Microchip PIC18F4550, and a Maxim-developed SHA-1 Verilog implementation (DSSHA1) used in conjunction with a Xilinx Spartan®-3A XC3S400A FPGA. Development capabilities for the host interface to Maxim's SHA-1 slaves are similarly supported with multiple options including the Maxim DS2482-100 I²C-to-1-Wire line driver, software generation of 1-Wire waveforms with the PIC18F4550, and a Verilog implementation (DS1WM) with the Xilinx FPGA. The EV kit can be used alone or controlled with a PC over RS-232 or USB interfaces. Microcontroller software can be installed and tested through an in-circuit debugger port. A JTAG port allows changing the FPGA programming through standard Xilinx development tools. With its expansion ports (40 pins for the microcontroller, 120 pins for the FPGA), the board can be the development platform for complex designs.
