FEATURES  
DESCRIPTION  
2
•
1024 bits of One-Time Programmable (OTP)  
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.  
EPROM For Storage Of User-Programmable  
Configuration Data

Factory-Programmed Unique 64-Bit  
Identification Number  
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.  
Bus-Interface Architecture Allowing Multiple  
bq2022As Attached to a Single Host  
Single-Wire Interface to Reduce Circuit Board  
Routing  
Synchronous Communication Reduces Host  
Interrupt Overhead  
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.
