DS28CN01U-A00+T - Maxim Integrated Products - 1Kb I2C/SMBus EEPROM with SHA-1 Engine

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.
