... STOP bit and the completion of any internal operations. MEMORY RESET: After an interruption in protocol, power loss or system reset, any 2- wire part can be reset by following these steps: 1. Clock cycles. 2. Look for SDA high in each cycle while SCL is high. 3. Create a start condition as SDA is high. AT24C128SC/AT24C256SC 5 ...

... Device Addressing Write Operations AT24C128SC/AT24C256SC 8 The 128K/256K EEPROM requires an 8-bit device address word following a start condi- tion to enable the chip for a read or write operation (refer to Figure 8). The device address word consists of a mandatory one, zero sequence for the first four most signifi- cant bits as shown ...

... Once the device address word and data word address are clocked in and acknowledged by the EEPROM, the microcontroller must generate another start condition. The microcontroller now initiates a current address read by sending a device address with the read/write select bit high. The EEPROM acknowledges the device AT24C128SC/AT24C256SC ...
