DS28E16

1-Wire Secure SHA-3 Authenticator

General Description

The DS28E16 secure authenticator combines FIPS202-

compliant Secure Hash Algorithm (SHA-3) challenge and

response authentication with secured EEPROM.

Beneﬁts and Features

● Robust Countermeasures Protect Against Security

Attacks

• All Stored Data Cryptographically Protected from

Discovery

The device provides a core set of cryptographic tools

derived from integrated blocks including a SHA-3 engine,

256 bits of secured user EEPROM, a decrement-only

counter and a unique 64-bit ROM identification number

(ROM ID). The unique ROM ID is used as a fundamental

input parameter for cryptographic operations and serves

as an electronic serial number within the application. The

● Efficient Secure Hash Algorithm Authenticates

Peripherals

• FIPS 202-Compliant SHA-3 Algorithm for

Challenge/Response Authentication

• FIPS 198-Compliant Keyed-Hash Message

Authentication Code (HMAC)

device communicates over the single-contact 1-Wire bus.

● Supplemental Features Enable Easy Integration into

End Applications

The communication follows the 1-Wire protocol with the

ROM ID acting as node address in the case of a multidevice

1-Wire network.

• 17-Bit One-Time Settable, Nonvolatile Decrement-

Only Counter with Authenticated Read

• Secure Storage for Secrets

• 256 Bits of Secure EEPROM for User Data

• Unique and Unalterable Factory Programmed

64-Bit Identiﬁcation Number (ROM ID)

• Advanced 1-Wire Protocol Minimizes Interface to

Single Contact

Applications

● Medical Tools/Accessories Authentication and

Calibration

● Accessory and Peripheral Secure Authentication

● Battery Authentication and Charge Cycle Tracking

• Full-Time Overdrive Communication Speed

• Internal Parasite Power Capacitor

• Operating Range: 1.71V–3.63V, -40°C to +85°C

• WLP and TDFN-EP Packages
