Description

The 24LC128T-I/MNY is a 128-kilobit (16 kilobytes) Electrically Erasable Programmable Read-Only Memory (EEPROM) device produced by Microchip Technology. It operates in a voltage range of 1.7V to 5.5V and uses an I2C serial interface, which allows for easy integration with microcontrollers and other digital systems. The device is organized as 16,384 bytes and supports up to 1 million erase/write cycles with a data retention of over 200 years, making it highly reliable for data storage applications.
Key features include byte-level and page-level write capabilities, with a page size of 64 bytes for efficient mass data handling. Its low-power design ensures minimal power consumption during both active and standby modes. The 24LC128T-I/MNY is housed in a small form factor, such as SOT-23, making it suitable for compact applications. This EEPROM is often used in consumer electronics, automotive systems, and industrial applications where non-volatile memory is needed for storing calibration data, configuration settings, or user preferences.
