DS28E15

DeepCover Secure Authenticator with 1-Wire SHA-256 and 512-Bit User EEPROM

General Description

DeepCover™ embedded security solutions cloak sensitive

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) combines

crypto-strong bidirectional secure challenge-and-response

authentication functionality with an implementation based

on the FIPS 180-3-specified Secure Hash Algorithm (SHA-

256). A 512-bit user-programmable EEPROM array provides

nonvolatile storage of application data. Additional protected

memory holds a read-protected secret for SHA-256 opera-

tions and settings for memory protection control. Each device

has its own guaranteed unique 64-bit ROM identification num-

ber (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 authentication 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 embedded DS28E15 is authentic. Host-to-slave authenti-

cation is used to protect DS28E15 user memory from being

modified by a unauthentic host. The DS28E15 communicates

over the single-contact 1-WireM 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.

● 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

= 1.1kΩ

MAXIMUM I C BUS CAPACITANCE 320pF
