Quick Detail:
1Kb I2C/SMBus EEPROM with SHA-1 Engine
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 32-byte pages. 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 industrystandard I2C-compatible and SMBus™-compatible interface. The SMBus timeout feature resets thedevice’s interface if a bus-timeout fault condition is detected.
Applications:
♦ 1024 Bits of EEPROM Memory Partitioned Into
Four Pages of 256 Bits
♦ Dedicated Hardware-Accelerated SHA-1 Engine
for Generating SHA-1 MACs
♦ EEPROM Memory Pages Can Be Individually
Copy Protected or Put Into EPROM Mode
(Program from 1 to 0 Only)
♦ Write Access Requires Knowledge of the Secret
and the Capability of Computing and Transmitting
a 160-Bit MAC as Authorization
