The IS24C128B-2GLI is a 128Kbit (16K x 8) CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) from ISSI (Integrated Silicon Solution Inc.). This EEPROM provides non-volatile data storage, meaning that the data is retained even when power is removed. It communicates using the I2C serial interface, making it easy to integrate into microcontroller-based systems.

Applications:

• Data storage in embedded systems
• Configuration storage
• Serial presence detect (SPD) in memory modules
• User preference storage
• Data logging

Features:

• 128Kbit (16K x 8) Memory: Provides 128Kbits of non-volatile storage.
• I2C Serial Interface: Simple two-wire interface for easy communication.
• Low Voltage Operation: Operates from a low supply voltage.
• Write Protect Feature: Protects the memory contents from accidental writes.
• Page Write Mode: Allows for efficient writing of multiple bytes at a time.
• Self-Timed Write Cycle: Simplifies the write operation.

Benefits:

• Non-Volatile Data Storage: Retains data even when power is off.
• Easy Integration: I2C interface simplifies integration into microcontroller systems.
• Low Power Consumption: Reduces power consumption in battery-powered devices.
• Data Protection: Write protect feature prevents accidental data loss.
• Fast Write Operations: Page write mode improves write performance.

Additional Details:

The IS24C128B-2GLI typically operates at frequencies up to 400 kHz with standard mode and up to 1 MHz with fast mode I2C. The device is available in a variety of packages, including SOIC and TSSOP. The write protect feature can be enabled to prevent accidental overwriting of the memory contents. The page write mode allows for writing up to a certain number of bytes (typically 64 bytes) in a single write operation, improving write speed. The self-timed write cycle simplifies the write operation by automatically timing the write process. The "2GLI" suffix likely refers to the specific package type, speed grade, and temperature range. The manufacturer's datasheet provides detailed specifications, including timing diagrams, electrical characteristics, and package dimensions. Careful consideration of the datasheet is essential for proper application and integration of the EEPROM into the target system.
