Product InformationFeatures
SDQ is a trademark of Texas Instruments. Description
The bq2022A 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 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 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. |
