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  
1-Wire is a registered trademark of Maxim Integrated Products, Inc.  
• ±8kV HBM ESD Protection (typ)  
• 3.5µA (typ) Input Load Current
