EPROM OTP 1K-Bit 4Pages x 256 3-Pin SOT-23 T/R

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 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.
