Vue d'ensemble

Description

The 24LC64-I/SN is an I2C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Read-Only Memory) chip with a capacity of 64 kilobits (8 kilobytes). This memory device is designed for applications requiring non-volatile storage, meaning it retains data even when power is removed.
Key features include a wide operating voltage range (typically 1.8V to 5.5V), a fast data transfer rate (up to 1 MHz), and the ability to write and erase data in blocks or bytes. The 24LC64-I/SN supports multiple device addressing, allowing up to eight devices to be connected on the same bus, making it versatile for various applications, including consumer electronics, automotive systems, and industrial controls.
The chip is suitable for applications where data retention and reliability are critical, and it uses a simple two-wire interface for communication. This makes it easy to integrate into microcontroller-based systems.

Features

The 24LC64-I/SN is a 64 Kbit (8 Kbyte) I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) with several key features:
1. I2C Interface: Supports standard (100 kHz) and fast mode (400 kHz) for communication.
2. Memory Organization: Structured as 8 pages of 256 bytes each, allowing efficient data management.
3. Write Protection: Features hardware write protection options to safeguard data integrity.
4. Endurance: Capable of 1,000,000 write cycles and data retention up to 100 years.
5. Operating Voltage: Functions over a wide voltage range of 2.5V to 5.5V, making it suitable for various applications.
6. Low Power Consumption: Ideal for battery-operated devices due to its low standby and active current consumption.
7. Multiple Device Capability: Allows multiple devices on the same I2C bus through unique addresses.
8. Byte and Page Write: Supports both byte and page write operations for flexibility.
These features make the 24LC64-I/SN suitable for applications in consumer electronics, automotive, and industrial systems.

Package

The 24LC64-I/SN is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) format. This surface mount package is designed for compact applications, providing a space-efficient solution for integrating the EEPROM into electronic circuits.

Pinout

The 24LC64-I/SN is an I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) with a pin count of 8.
Pin Functions:
1. VCC (Pin 1): Power supply pin (typically 2.5V to 5.5V).
2. GND (Pin 2): Ground reference.
3. SDA (Pin 3): Serial Data Line for data transfer.
4. SCL (Pin 4): Serial Clock Line for synchronization of data transfer.
5. WP (Pin 5): Write Protect; when tied to VCC, prevents write operations.
6. A0 (Pin 6): Device Address Selection pin; can be tied to GND or VCC to set the device address.
7. A1 (Pin 7): Device Address Selection pin; similar function as A0.
8. A2 (Pin 8): Device Address Selection pin; used to further differentiate multiple devices on the same I2C bus.
The 24LC64-I/SN is commonly used for data storage applications due to its non-volatile memory capabilities.
