Product Summary

The AT24C512B-PU25 is a Two-wire Serial EEPROM. The AT24C512B-PU25 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The AT24C512B-PU25 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. In addition, the AT24C512B-PU25 is available in 1.8V (1.8V to 3.6V) and 2.5V (2.5V to 5.5V) versions.
