bq2022A Evaluation Software
The bq2022A is a 1 K-bit serial EPROM containing a factory-programmed, unique 48-bit identification
number, 8-bit CRC generation, and an 8-bit family code. A 64-bit status register controls write protection
and page redirection.
The purpose of the evaluation software is to demonstrate the functionality of the bq2022A. The bq2022A
evaluation board can be used for one or two ICs.
The bq2022A is ideal for applications such as battery pack configuration parameters, record maintenance,
asset tracking, product revision status, and access-code security.
