AT24C1024B is a 1.048576-bit serial electrically erasable and programmable read only memory (EEPROM) organized as 131,072 words of 8 bits each. Its device's cascadable feature allows up to four 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. The device provides 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead TSSOP, 8-ball dBGA2 and 8-lead Ultra Thin SAP packages to save space. In addition, the entire family provides 1.8V (1.8V to 3.6V) and 2.5V (2.5V to 5.5V) versions.
The AT24C1024B is a 1‑Mbit (131,072 × 8) serial EEPROM offering low‑voltage operation (1.8 V or 2.5 V versions) and a two‑wire I²C interface. It is available in multiple 8‑lead packages and supports up to four devices on a common bus.
