2-WIRE CMOS SERIAL E2PROM
S-24CS01A/02A/04A/08A
Rev.4.4_00
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.
