DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.

The DeepCover Secure Memory (DS28C22) evaluation system (EV system) consists of a single evaluation kit (EV kit) that includes a package of five DS28C22 devices in an 8-pin TDFN package with exposed pad, a DS9121Q+ evaluation board (EV board), and a DS9400# USB-to-I2C module for PC connectivity. The DS28C22 combines crypto-strong, bidirectional, secure challenge-and-response authentication functionality with an implementation based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256). The memory is organized as 3072 bits of user EEPROM partitioned into 12 pages of 256 bits. Each page is user programmable with irreversible EEPROM protection modes including authentication, write and read protect, encryptions, and OTP/EPROM emulation. Additional protected memory holds one read-protected secret for SHA-256 operations and settings for user memory control. Each device has its own guaranteed, unique, 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. This unique ROM ID is used as a fundamental input parameter for cryptographic operations and also serves as an electronic serial number within user applications. This EV system provides a complete hardware and software system to exercise the features of the DS28C22. The evaluation software runs under Windows® 8, Windows 7, Windows Vista®, and Windows XP® operating systems, providing a handy user interface to exercise the DS28C22 features.

Note: The DS9121Q+ and DS9400# subcomponents are not available for direct sale outside of evaluation kits.
