Product details

Authentication IC for secure BOM integration

The DS28E22Q+T is a dedicated authentication chip from Analog Devices' DeepCover® series, built for cryptographic key storage and challenge-response verification in embedded systems. Its primary function is to authenticate peripheral modules, consumables, or field-replaceable units against a host controller, preventing clone or gray-market parts from operating in the system.

Housed in a 6-WDFN with an exposed pad (supplier package 6-TDFN, 3x3 mm), the DS28E22Q+T requires a thermal-land pattern on the PCB to sink heat from the die. Surface-mount assembly follows standard lead-free reflow profiles for the 3x3 mm DFN footprint.
