Product Details

The DS28E15 evaluation system (EV system) provides the hardware and software necessary to evaluate and program the DS28E15 DeepCover^® Secure Authenticator. EV system operation requires a host PC for user-friendly evaluation.

This evaluation system includes a DS9400 USB-to-I²C PC adapter, a DS2465 EV board, a DS9120Q+ evaluation socket board for a TDFN DS28E15, and five DS28E15 sample devices in a TDFN package. The EV software runs on Windows^® 8, Windows 7, Windows Vista^®, and Windows XP^® operating systems. Detailed instructions for downloading and installing software, as well as general EV system operation are included in the EV system data sheet; software and documentation are available at the link above.

Note: The DS2465 EV board and DS9400# subcomponents are not available for direct sale outside of evaluation systems. A data sheet specific to DS9400# is not available.
