Description

The AT24C256B provides 262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 32,768 words of 8 bits each. The device's cascadable feature allows up to eight devices to share a common two-wire bus. The AT24C256B is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT24C256B are available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead MAP, 8-lead TSSOP, and 8-ball dBGA2 packages. In addition, the entire family is available in a 1.8V (1.8V to 3.6V) version.
