Abridged Data Sheet  
DS28E01-100  
1K-Bit Protected 1-Wire EEPROM with  
SHA-1 Engine  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS28E01-100 combines 1024 bits of EEPROM  
with challenge-and-response authentication security  
implemented with the ISO/IEC 10118-3 Secure Hash  
Algorithm (SHA-1). The 1024-bit EEPROM array is  
configured as four pages of 256 bits with a 64-bit  
scratchpad to perform write operations. All memory  
pages can be write protected, and one page can be  
put in EPROM-emulation mode, where bits can only  
be changed from a 1 to a 0 state. Each DS28E01-  
100 has its own guaranteed unique 64-bit ROM  
registration number that is factory lasered into the  
chip. The DS28E01-100 communicates over the  
single-contact 1-Wire® bus. The communication  
follows the standard Dallas Semiconductor 1-Wire  
protocol with the registration number acting as node  
address in the case of a multi-device 1-Wire network.  
ƒ
1024 bits of EEPROM memory partitioned into  
four pages of 256 bits  
ƒ
On-chip 512-bit SHA-1 engine to compute 160-bit  
Message Authentication Codes (MAC) and to  
generate secrets  
ƒ
Write access requires knowledge of the secret  
and the capability of computing and transmitting  
a 160-bit MAC as authorization  
ƒ
ƒ
ƒ
User-programmable page write-protection for  
page 0, page 3 or all four pages together  
User-programmable OTP EPROM emulation  
mode for page 1 ("write to 0")  
Communicates to host with a single digital signal  
at 15.3k bits or 125k bits per second using  
1-Wire protocol
