2-WIRE CMOS SERIAL E²PROM
S-24CS16A
„ 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.
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
E²PROM initiates a write cycle.
