Description

The 24LC64-I/SN is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) chip manufactured by Microchip Technology. It offers a storage capacity of 64 kilobits, organized as 8,192 words of 8 bits each. The chip utilizes an I²C (Inter-Integrated Circuit) bus for communication, making it suitable for applications requiring low-power and serial data storage.
Key features include a wide operating voltage range of 1.7V to 5.5V, which makes it compatible with various microcontroller systems, and a low standby current, enhancing battery-operated applications. It supports a standard 7-bit I²C addressing, allowing up to eight devices on the same bus by configuring three address pins.
The 24LC64-I/SN has a page write capability of up to 32 bytes, facilitating efficient data writing and retrieval. It is known for its high reliability with over 1 million erase/write cycles and data retention of over 200 years. The EEPROM is available in an 8-lead Small Outline Integrated Circuit (SOIC) package, making it easy to integrate into compact designs.
