• Manufacturer Part Number: at24c256c
• Description: Two-wire Serial Eeprom
• Manufacturer: ATMEL Corporation

SEQUENTIAL READ: Sequential reads are initiated by either a current address read or a random address read. After
the microcontroller receives a data word, it responds with an acknowledge. 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
sequential read operation is terminated when the microcontroller does not respond with a “0” but does generate a
following stop condition (refer to Figure 13).
