DESCRIPTION

The bq2024 is a 1.5K-bit serial EPROM containing a

factory-programmed, unique 48-bit identification

number, 8-bit CRC generation, and the 8-bit family

code (09h). A 64-bit status register controls write

protection and page redirection.

The bq2024 SDQ™ interface requires only a single

connection and a ground return. The DATA pin is

also the sole power source for the bq2024. The bus

architecture allows multiple SDQ devices to be

connected to a single host.

The small surface-mount package options saves

printed-circuit-board space, while the low cost makes

it ideal for applications such as battery pack

configuration parameters, record maintenance, asset

tracking, product-revision status, and access-code

security.
