It handles cryptographic challenge-response handshakes without loading the host microcontroller, making it a drop-in block for anti-cloning and tamper-detection circuits. The 6-TDFN package (3x3 mm) with exposed pad keeps the board footprint small, and the pad helps pull heat out if the part is running continuous authentication cycles. ## Lifecycle and sourcing posture The DS28EL22Q+T carries an Active lifecycle status from the manufacturer, with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For BOM planning, this part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.","metaTitle":"DS28EL22Q+T Authentication Chip, DeepCover, 6-TDFN, Active","metaDescription":"Maxim Integrated DS28EL22Q+T DeepCover Authentication Chip in 6-TDFN package.
