Abridged Data Sheet
DS28CN01
1Kbit I虜C/SMBus EEPROM
with SHA-1 Engine
www.maxim-ic.com
GENERAL DESCRIPTION
The DS28CN01 combines 1024 bits of EEPROM
with challenge-and-response authentication security
implemented
with
the
Federal
Information
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 I虜C- and SMBus鈩?compatible interface.
The SMBus timeout feature resets the device鈥檚
interface if a bus-timeout fault condition is detected.
FEATURES
1024 Bits of EEPROM Memory Partitioned
Into Four Pages of 256 Bits
Dedicated Hardware-Accelerated SHA Engine
for Generating SHA-1 MACs
EEPROM Memory Pages can be Individually
Copy-Protected or Put Into an EPROM Mode
