ABRIDGED DATA SHEET  
219-0008; Rev 1; 3/12  
1-Wire SHA-1 Authenticated 1Kb  
EEPROM with 1.8V Operation  
DS8E02  
General Description  
Features  
The DS28E02 combines 1024 bits of EEPROM with  
challenge-and-response authentication security imple-  
mented with the FIPS 180-3 Secure Hash Algorithm  
(SHA-1). The 1024-bit EEPROM array is configured as  
four pages of 256 bits with a 64-bit scratchpad to per-  
form write operations. All memory pages can be write  
protected, and one page can be put in EPROM-emula-  
tion mode, where bits can only be changed from a 1 to  
a 0 state. Each DS28E02 has its own guaranteed  
unique 64-bit ROM registration number that is factory  
installed into the chip. The DS28E02 communicates  
o 1024 Bits of EEPROM Memory Partitioned Into  
Four Pages of 256 Bits  
o On-Chip 512-Bit SHA-1 Engine to Compute 160-  
Bit Message Authentication Codes (MACs) and to  
Generate Secrets  
o Write Access Requires Knowledge of the Secret  
and the Capability of Computing and Transmitting  
a 160-Bit MAC as Authorization  
o User-Programmable Page Write Protection for  
®
Page 0, Page 3, or All Four Pages Together  
over the single-contact 1-Wire bus. The communica-  
tion follows the standard 1-Wire protocol with the regis-  
tration number acting as the node address in the case  
of a multidevice 1-Wire network.  
o User-Programmable OTP EPROM Emulation Mode  
for Page 1 (“Write to 0”)  
o Communicates to Host with a Single Digital  
Signal at 12.5kbps or 35.7kbps Using 1-Wire  
Protocol  
Applications  
Reference Design License Management  
System Intellectual Property Protection  
Sensor/Accessory Authentication and Calibration  
Medical Consumable Authentication  
o Switchpoint Hysteresis and Filtering to Optimize  
Communication Performance in the Presence of  
Noise  
o Reads and Writes Over 1.75V to 3.65V Voltage  
Range from -20°C to +85°C  
Printer Cartridge Configuration and Monitoring  
o 6-Lead TSOC and TDFN Packages  
Typical Operating Circuit
