... Description The AT24C128B provides 131,072 bits of serial electrically erasable and programma- ble read-only memory (EEPROM) organized as 16,384 words of 8 bits each. The device’s cascadable feature allows up to eight devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential ...

... If the pin is left floating, the WP pin will be internally pulled down to GND. However, due to capacitive coupling that may appear during customer applications, Atmel recommends always connecting the WP pins to a known state. When using a pull-up resistor, Atmel recommends using 10kΩ or less. ...

... Upon a compare of the device address, the EEPROM will output a “0” compare is not made, the device will return to a standby state. DATA SECURITY: The AT24C128B has a hardware data protection scheme that allows the user to write protect the whole memory when the WP pin AT24C128B 8 ...

... The data word address lower six bits are internally incremented following the receipt of each data word. The higher data word address bits are not incremented, retaining the memory page row location. When the word address, internally generated, reaches the page boundary, the fol- lowing byte is placed at the beginning of the same page. If more than 64 data words are transmitted to the EEPROM, the data word address will “ ...

... 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 “1” is clocked in and acknowledged by the EEPROM, the current address data word is serially clocked out. The microcontroller does not respond with an input “ ...
