1K-bit EPROM For Battery Pack Identification

The BQ2022 is a 1K-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 BQ2022 SDQ? Interface (TI's proprietary serial Communications protocol) requires only a single connection and a ground return. The DATA pin is also the sole power source for the bq2022. 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.
