BQ2022A
- 1024 bits of one-time programmable (OTP) EPROM for storage of user-programmable configuration data
- Factory-programmed unique 64-bit identification number
- Single-wire interface to reduce circuit board routing
- Synchronous communication reduces host interrupt overhead
- 15-KV IEC 61000-4-2 ESD compliance on data pin
- No standby power required
- Available in a 3-pin SOT-23 package and TO-92 package
The BQ2022A is a 1-Kbit 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.
