Product Details

The DS2704 evaluation kit (EV kit) makes performance evaluation, software development, and prototyping with the DS2704 1280 bit EEPROM with SHA-1 Authentication easy. The evaluation board interfaces to a PC through a DS9123O USB Adapter and RJ-11 cable connection. All related data sheets along with the evaluation software can be found on our website at www.maximintegrated.com.

The DS2704 EV kit evaluation software gives the user complete control of all SHA-1 and Memory functions of the DS2704 as well as the various other commands.

The evaluation board circuit is designed to provide the DS2704 with a stable environment to perform SHA-1 Calculations and program and read the DS2704. Kit demonstration boards will vary as they are improved upon over time. For information on the demonstration board circuits refer to our website at www.maximintegrated.com.
