2-WIRE CMOS SERIAL E²PROM
S-24C02BPPHL
„ Operation
1. Start condition
When the SDA line changes from “H” to “L” with the SCL line at “H”, the device is in the start condition.
All operations begin from the start condition.
2. Stop condition
When the SDA line changes from “L” to “H” with the SCL line at “H”, the device is in the stop condition.
When the device receives the stop condition signal during a read sequence, the read operation is
interrupted, and the device enters standby mode.
When the device receives the stop condition signal during a write sequence, the retrieval of write data is
halted, and rewriting the E²PROM starts.
