... Die Sales: Wafer Form, Tape and Reel and Bumped Wafers 2. 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 ...

... 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. 5296A–SEEPR–1/08 AT24C128B page 8.) A device 3 ...

... As long as the EEPROM receives an acknowledge, it will continue to increment the data word address and serially clock out sequential data words. When the memory address limit is reached, the data word address will “roll over” and the sequential read will continue. The AT24C128B 10 Current Address Read Figure 9-2) ...
