DS28CN01

1Kbit I²C/SMBus EEPROM

with SHA-1 Engine

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

The DS28CN01 combines 1024 bits of EEPROM

with challenge-and-response authentication security

1024 Bits of EEPROM Memory Partitioned

Into Four Pages of 256 Bits

implemented

with

the

Federal

Information

Dedicated Hardware-Accelerated SHA Engine

for Generating SHA-1 MACs

EEPROM Memory Pages can be Individually

Copy-Protected or Put Into an EPROM Mode

(Program from 1 to 0 Only)

Publications (FIPS) 180-1/180-2 and ISO/IEC 10118-

3 Secure Hash Algorithm (SHA-1). The memory is

organized as four pages of 32 bytes each. Data

copy-protection and EPROM emulation features are

supported for each memory page. Each DS28CN01

has a guaranteed unique factory-programmed 64-bit

registration number. Communication with the

DS28CN01 is accomplished through an industry

standard I²C- and SMBus™-compatible interface.

The SMBus timeout feature resets the device’s

interface if a bus-timeout fault condition is detected.

Write Access Requires Knowledge of the

Secret and the Capability of Computing and

Transmitting a 160-Bit MAC as Authorization

Unique, Factory-Programmed, and Tested

64-Bit Registration Number Assures Absolute

Traceability Because No Two Parts are Alike

Endurance 200k Cycles at +25°C

Serial Interface User Programmable for I²C

Bus and SMBus Compatibility

APPLICATIONS

Supports 100kHz and 400kHz I²C
