ABRIDGED DATA SHEET

1-Wire SHA-1 Authenticator  
General Description  
Features  
S Dedicated Hardware-Accelerated SHA-1 Engine  
The DS28E10 combines secure challenge-and-response  
authentication functionality based on the FIPS 180-3  
specified Secure Hash Algorithm (SHA-1) with 224 bits  
of one-time programmable user EPROM in a single  
chip. Once written, the memory is automatically write  
protected. Additionally, each device has its own guaran-  
teed unique 64-bit ROM identification number (ROM ID)  
that is factory programmed into the chip. Memory writes  
are performed 4 bytes at a time. A secure and low-cost  
factory programming service is available to preprogram  
device data, including the SHA-1 security data compo-  
nents. The device communicates over the single-contact  
1-Wire® bus. The communication follows the standard  
1-Wire protocol with the ROM ID acting as node address  
in the case of a multidevice 1-Wire network.  
for Generating SHA-1 MACs  
S One Page of 28 Bytes User OTP EPROM  
S Irreversible Write Protection
