... Description The AT24C128/256 provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The device’s cascadable feature allows devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applica- tions where low power and low voltage operation are essential ...

... WRITE PROTECT (WP): The write protect input, when tied to GND, allows normal write operations. When WP is tied high all write operations to the memory are inhib- CC ited. If left unconnected internally pulled down to GND. Switching prior to a write operation cre- CC ates a software write protect function ...

... 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 follow- ing these steps: (a) Clock cycles, (b) look for SDA high in each cycle while SCL is high and then (c) create a start condition as SDA is high ...

... This address stays valid between operations as long as the CC chip power is maintained. The address “roll over” during read is from the last byte of the last memory page, to the first byte of the first page. Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM, the current address data word is serially clocked out ...
