Product Details
DS28E30X+T - 1-Wire ECDSA Secure Authenticator, 4-Bump WLP
DS28E30X+T from Analog Devices is a 1-Wire ECDSA P-256 secure authenticator in a 4-bump wafer-level package, supplied on tape and reel.
Specifications were checked against the manufacturer data sheet; distributor stock and prices require live confirmation.
Overview
DS28E30 uses an ECC P-256 engine for asymmetric challenge-response authentication. It includes a true random number generator, secure EEPROM and a factory-programmed 64-bit ROM ID. The X+T order code is the 4-bump WLP tape-and-reel version.
Key Advantages
ECDSA P-256 authentication protects accessory and peripheral identity.
A four-bump wafer-level package supports compact authenticated products.
Supplied in the documented tape-and-reel surface-mount package.
Electrical and environmental limits are defined by the official data sheet.

Replacement Considerations
DS28E30X+U is a verified catalog entry. DS28E30X+U uses the same WLP family with different ordering media; verify ADI shipping terms and assembly requirements.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Analog Devices DS28E30 Rev. 3 gives the X+T 4-WLP order code, A1/B2/B1/A2 bump functions, and electrical limits.
Applications
Authenticates battery packs and tracks authorized charge cycles.
Supports authentication and calibration records for replaceable tools.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
