Maxim Integrated │ 12 www.maximintegrated.com Evaluates: DS28C39 and DS2476DS28C39 Evaluation System EV Kit Supported Functions The DS28C39 EV kit program is designed as a usage example. It includes the ability to either use the built-in software ECDSA engine or the DS2476BQ+ coprocessor as the host compute engine. The default is to use the soft- ware ECDSA engine. To use the coprocessor, go under the Settings menu, then ECDSA Engine , and select DS2476. The GUI displays all the I2C sequences for each step performed to assist the firmware engineer. See Table 1 for descriptions of the functions in the GUI. Detailed Hardware Description The DS28C39 EV kit hardware includes the MAXQ1010 microcontroller with USB and two socket adapters, DS9121AQ and DS9121BQ, which are made to contain the DS2476 device or DS28C39 device. The MAXQ1010 is loaded with firmware to function as a virtual COM port that bridges UART signaling to I 2C and 1-Wire. Optionally, the DS2476 functions to off load the ECDSA I2C computations to perform signature. The DS28C39 slave functions to perform ECDSA Public-Key signatures during authentication and contains memory space for the necessary elements. Table 1. GUI Setup and Usage Flows Supported *Software supports all flows in Table 1. needed to set up the system Authority Key pair, Write Key pair, and the Write Certificate. this contains the operations needed to set up the DS28C39 device. Read RNG Performs the operations to generate a random number from the DS28C39 device. This is a FIPS/NIST compliant true random number generator (TRNG).
