DS2704
1280-Bit EEPROM with SHA-1 Authentication
www.maxim-ic.com
GENERAL DESCRIPTION
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.
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.
