2-WIRE SERIAL E2PROM
S-24C32C/64C
Operation
1. Start Condition
Start is identified by a high to low transition of the SDA line while the SCL line is stable at high.
Every operation begins from a start condition.
Rev.4.0_02_H
2. Stop Condition
Stop is identified by a low to high transition of the SDA line while the SCL line is stable at high.
When a device receives a stop condition during a read sequence, the read operation is interrupted, and the device
enters standby mode.
When a device receives a stop condition during a write sequence, the reception of the write data is halted, and the S-
24C32C/64C initiates a write cycle.
