The DS28E16Q+T is packaged in a TDFN (Thin Dual Flat No-lead) package. Specifically, it is a 6-pin TDFN with a 3mm x 3mm footprint. This package type is suitable for compact and low-profile applications.

The DS28E16Q+T is a secure authenticator IC from Maxim Integrated, featuring a 1-Wire interface. It has a 3-pin package configuration:
1. DQ (Data Input/Output): This is the main communication pin for the 1-Wire interface, used for both data input and output. It enables communication between the DS28E16 and a host controller.
2. GND (Ground): This pin provides the return path for the power supply and signals. It must be connected to the ground of the host system.
3. NC (No Connect): This pin is not internally connected and typically serves no functional purpose. It should be left unconnected.
The primary function of the DS28E16 is to provide secure authentication with support for SHA-256 cryptographic operations, which are crucial for applications requiring secure validation and data protection.
