... Rev 2; 11/09 2 1Kb I C/SMBus EEPROM with SHA-1 Engine General Description The DS28CN01 combines 1024 bits of EEPROM with challenge-and-response authentication security imple- mented 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 ...

... Operating Temperature Range ...........................-40°C to +85°C Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... Slave Address/Direction Byte To be individually accessed, each device must have a slave address that does not conflict with other devices on the bus. The slave address to which the DS28CN01 responds is shown in Figure 1. The slave address is part of the slave-address/direction byte. The upper 3 bits of the DS28CN01 slave address are set to 101b. ...

... DS28CN01 does not acknowledge any bytes that it refuses by leaving SDA high during the high period of the acknowledge-related clock pulse. See the Read and Write section in the full data sheet for a detailed list of situations where the DS28CN01 does not acknowl- edge. Not Acknowledged by Master SU:DAT At some time when receiving data, the master must ter- minate a read access ...

... According to the I C specification, a slave device must be able to sink at least 3mA SMBus specification requires a current sink capability of 4mA at +0.4V. The DS28CN01 can sink at least 4mA at +0.4V V over its entire operating voltage range. OL This DC characteristic determines the minimum value of the pullup resistor: R ...
