DESCRIPTION
The bq2024 is a 1.5K-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 bq2024 SDQ™ interface requires only a single
connection and a ground return. The DATA pin is
also the sole power source for the bq2024. 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.
