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

Factory-Programmed Unique 64-Bit  
Identification Number  
Bus-Interface Architecture Allowing Multiple  
bq2022s Attached to a Single Host  
The bq2022 SDQ interface (TI’s proprietary serial  
Single-Wire Interface to Reduce Circuit  
Board Routing  
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.  
Synchronous Communication Reduces Host  
Interrupt Overhead  
D
No Standby Power Required  
D
Available in a 3-Pin SOT23 Package  
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.
