Abridged Data Sheet  
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  
ƒ
ƒ
ƒ
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.

ƒ
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
