Description

The AT24C64A-10TI-2.7 is a high-performance electronic component in the memory category. It provides 65,536 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 8192 words of 8 bits each. This device is optimized for use in industrial and commercial applications where low power and low voltage operation are essential. With its cascadable feature, up to 8 devices can share a common 2-wire bus. The AT24C64A-10TI-2.7 is available in various package options such as 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, and 8-lead TSSOP. It can be accessed via a 2-wire serial interface and is available in both 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.
