Description for the BQ2022A
The BQ2022A is a 1-Kbit 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 BQ2022A SDQ™ interface requires only a single connection and a ground return. The DATA pin is also the sole power source for the BQ2022A.
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.
