24LC256-I/ST

The 24LC256-I/ST is a 256 Kbit (32 K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) device manufactured by Microchip Technology. This memory chip is designed for applications that require non-volatile storage, meaning it retains data even when power is removed.

Key Features:

1. Memory Organization: The 24LC256 is organized as 32,768 words of 8 bits each, allowing for efficient data storage and retrieval. This organization makes it suitable for applications that require a moderate amount of data storage.

2. Interface: The device communicates with microcontrollers and other digital systems via a 2-wire I2C (Inter-Integrated Circuit) interface. This allows for easy integration into various electronic systems, as the I2C protocol is widely used in many applications.

3. Operating Voltage: The 24LC256 operates within a voltage range of 1.8V to 5.5V, making it versatile for use in low-power applications as well as standard voltage systems.

4. Data Retention: The EEPROM is designed for long-term data retention, with a typical data retention period of over 100 years. This makes it ideal for applications where data integrity over time is critical.

5. Write Endurance: The device supports a minimum of 1,000,000 write cycles per memory cell, ensuring that it can handle frequent updates without failure.

6. Page Write Capability: The 24LC256 supports page write operations, allowing users to write up to 16 bytes of data in a single operation. This feature enhances the efficiency of data writing processes.

7. Low Power Consumption: The device is designed for low power consumption, making it suitable for battery-operated devices. It has a typical active current of 1 mA and a standby current of just a few microamperes.

8. Temperature Range: The 24LC256 is rated for operation over a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial and automotive applications.

9. Package Options: The chip is available in various package types, including SOIC (Small Outline Integrated Circuit) and TSSOP (Thin Shrink Small Outline Package), allowing for flexibility in design and layout.
