The DS28E10 combines secure challenge-and-response authentication functionality based on the FIPS 180-3 specified Secure Hash Algorithm (SHA-1) with 224 bits of one-time programmable user EPROM in a single chip. Once written, the memory is automatically write protected. Additionally, each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. Memory writes are performed 4 bytes at a time. A secure and low-cost factory programming service is available to preprogram device data, including the SHA-1 security data components. The device communicates over the single-contact 1-Wire® bus. The communication follows the standard 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.

Product Detail

The DS28E10 evaluation kit (EV kit) provides the hardware and software necessary to evaluate and program the DS28E10 1-Wire SHA-1 authenticator in an easy-to-use PC environment. The EV kit enables engineers to evaluate the DS28E10 for potential design purposes or to support end-product development activity. EV kit operation requires a host PC. The EV kit hardware includes a USB-to-1-Wire PC adapter to which an included DS28E10 evaluation board with IC socket is attached. An included RJ11 cable connects the evaluation board to the USB-to-1-Wire adapter. PC-based EV kit software is available. Additionally, the EV kit software requires an installation of Maxim's 1-Wire drivers, Microsoft .NET framework Version 2.0, and Prolific's PL-2303 USB-to-serial driver. Detailed instructions for downloading and installing these components are included in the EV kit data sheet. The EV kit also includes samples of the DS28E10 1-Wire SHA-1 authenticator.
