DS2704 Datasheet 1280-bit Eeprom

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. DS2704 1280-Bit EEPROM with SHA-1 Authentication .maxim-ic.

General Description

The DS2704 provides 1280 bits of EEPROM data storage and a Secure Hash Algorithm (SHA) engine.

The Dallas 1-WireÒ interface enables serial munication 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.

Key Features
