DS2704  
1280-Bit EEPROM with SHA-1 Authentication  
www.maxim-ic.com  
GENERAL DESCRIPTION  
PIN CONFIGURATION  
The DS2704 provides 1280 bits of EEPROM data  
storage and a Secure Hash Algorithm (SHA) engine.  
The Dallas 1-Wire® interface enables serial  
communication on a single battery contact and the  
64-bit unique serial number allows multidrop  
networking and identification of individual devices.  
The 1280-bit memory is organized as 5 pages of 32  
bytes each and supports storage of battery cell  
characteristics, charging voltage, current, and  
temperature parameters, as well as battery pack  
manufacturing data. The EEPROM pages are in  
circuit rewritable and can be individually locked to  
write protect data.  
3mm × 3mm TDFN  
(TOP VIEWPADS ON BOTTOM)  
The DS2704 employs the Secure Hash Algorithm  
(SHA-1) specified in the Federal Information  
publication 180-1 and 180-2, and ISO/IEC 10118-3.  
SHA-1 provides a robust cryptographic solution to  
ensure battery packs or other peripherals have been  
manufactured by authorized sources. The DS2704  
processes a host transmitted challenge and the 64-  
bit secret key stored on chip to produce a 160-bit  
response for transmission back to the host. The  
secret key is never transmitted between the battery  
and the host.
