  • Description

    The AT24C256CI27 is a popular electronic component in the IC Chips category. It is a serial electrically erasable and programmable read-only memory (EEPROM) with a capacity of 262,144-bits. The device is organized into 32,768 words of eight bits each. It is designed to be cascaded, allowing up to eight devices to share a common two-wire bus. This component is commonly used in various industrial and commercial applications, thanks to its low-power and low-voltage operation. The AT24C256CI27 is available in space-saving package options such as 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead UDFN, and 8-ball VFBGA.
