The BL24LC64 is a 64K-bit EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by SHANGHAI BELLING CO., LTD. It is a serial EEPROM that uses the I2C interface for communication, making it suitable for storing small amounts of data in various electronic systems.

Applications

• Storage of configuration data in embedded systems
• Storage of user preferences
• Storage of calibration data
• Storage of serial numbers
• Data logging applications

Features

• Memory Size: 64K-bit (8K x 8)
• Interface: I2C (2-Wire Serial Interface)
• Operating Voltage: 2.5V to 5.5V
• Clock Frequency: Up to 400 kHz
• Write Cycle Time: Typically 5 ms
• Operating Temperature: -40°C to +85°C
• Package: SOIC-8, TSSOP-8

Benefits

• Non-Volatile Storage: Data is retained even when power is removed.
• I2C Interface: Simple 2-wire interface for easy integration with microcontrollers.
• Low Power Consumption: Suitable for battery-powered applications.
• Write Protection: Protects data from accidental overwrites.
• Wide Operating Voltage Range: Operates over a broad voltage range.

Additional Details

The BL24LC64 utilizes the I2C protocol for communication, which simplifies the interface to a microcontroller. The device features a page write mode, allowing multiple bytes to be written in a single operation, reducing the overall write time. The EEPROM has a typical endurance of 1,000,000 erase/write cycles. It is commonly used in applications where small amounts of non-volatile data storage are required, such as storing system configuration parameters or user preferences.
