DS28E15

DeepCover Secure Authenticator with

1-Wire SHA-256 and 512-Bit User EEPROM

General Description

DeepCover™ embedded security solutions cloak sensi-

tive data under multiple layers of advanced physical

security to provide the most secure key storage possible.

Beneﬁts and Features

● 512-Bit EEPROM with SHA-256 Authentication for

Reads and Writes

• Symmetric-Key-Based Bidirectional Secure

Authentication Model Based on SHA-256

• Strong Authentication with a High-Bit-Count User

Programmable Secret and Input Challenge

• 512 Bits of User EEPROM Partitioned Into Two

Pages of 256 Bits

• User-Programmable and Irreversible EEPROM

Protection Modes Including Authentication, Write

and Read Protect, and OTP/EPROM Emulation

• Unique Factory-Programmed, 64-Bit Identiﬁcation

Number

The DeepCover Secure Authenticator (DS28E15) com-

bines crypto-strong bidirectional secure challenge-and-

response authentication functionality with an imple-

mentation based on the FIPS 180-3-specified Secure

Hash Algorithm (SHA-256). A 512-bit user-program-

mable EEPROM array provides nonvolatile storage of

application data. Additional protected memory holds a

read-protected secret for SHA-256 operations and set-

tings for memory protection control. Each device has

its own guaranteed unique 64-bit ROM identification

number (ROM ID) that is factory programmed into the

chip. This unique ROM ID is used as a fundamental input

parameter for cryptographic operations and also serves

as an electronic serial number within the application. A

bidirectional security model enables two-way authen-

tication between a host system and slave-embedded

DS28E15. Slave-to-host authentication is used by a host

system to securely validate that an attached or embed-

ded DS28E15 is authentic. Host-to-slave authentication is

used to protect DS28E15 user memory from being modi-

fied by a unauthentic host. The DS28E15 communicates

● Minimalist 1-Wire Interface Lowers Cost and

Interface Complexity

• Reduces Control, Address, Data, Power, and

Programming Signals to a Single Data Pin

• ±8kV HBM ESD Protection (typ)

• 2-Pin SFN, 6-Pin TDFN-EP, and 6-Pin TSOC

Packages

• Operating Range: 3.3V ±10%, -40°C to +85°C

Typical Application Circuit

R = 1.1kΩ

MAXIMUM I C BUS CAPACITANCE 320pF

over the single-contact 1-Wire bus at overdrive speed.

The communication follows the 1-Wire protocol with the

ROM ID acting as node address in the case of a multi-

device 1-Wire network.
