The 24LC01BT-E/LT is a compact, serial EEPROM memory chip from Microchip, offering 128 bytes (1 Kilobit) of electronically erasable and programmable read-only memory. It operates via a serial I2C bus, making it ideal for applications requiring a small amount of data storage with minimal I/O pin usage. This tiny, yet powerful component is particularly suitable for storing settings, calibration data, or device IDs, often used in consumer electronics, communication devices, and automotive applications where space is at a premium. The EEPROM operates across a wide voltage range from 1.7V to 5.5V, accommodating various logic levels and providing design flexibility across 3.3V and 5V systems. Its small-package footprint allows for its integration into highly compact PCB designs, making it a popular choice for portable and space-sensitive applications. The 24LC01BT-E/LT supports a bidirectional data transfer protocol, enhancing its efficiency in data logging tasks. Its endurance and data retention capabilities ensure that data remains intact through extensive use, with the ability to withstand one million write cycles and retain data for over 100 years, a testament to its reliability and durability for long-term applications.
