AT24C512B is a low-power, low-voltage operation serial electrically erasable and programmable read-only memory (EEPROM) provides 524,288 bits of storage space, organized as 65,536 8-bit words. The device supports 8 devices sharing a common 2-wire bus, and can be used in many industrial and commercial applications where low power and low voltage operation are essential. The device provides 8-pin PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead TSSOP, 8-ball dBGA2 and 8-lead Ultra Thin SAP packages to meet the needs of different application scenarios.
The AT24C512B is a 512‑kilobit serial EEPROM offering low‑voltage operation (1.8 V to 5.5 V) and high reliability for industrial and commercial applications. It supports up to eight devices on a common two‑wire bus and is available in multiple compact packages such as 8‑lead PDIP, SOIC, TSSOP, and 8‑ball BGA.
Key specifications include a 1 MHz maximum clock rate, 5 ms write cycle time, 1 M write‑cycle endurance, and 40‑year data retention. Detailed electrical parameters, timing diagrams, and package dimensions are provided for designers.
