The Microchip 24LC01BT-I/OT: A Cornerstone of Serial Non-Volatile Memory

In the realm of embedded systems and electronics, the reliable storage of configuration data, calibration constants, or operational parameters is a fundamental requirement. The Microchip 24LC01BT-I/OT stands as a quintessential solution, offering a robust and highly accessible 1 Kbit of serial Electrically Erasable Programmable Read-Only Memory (EEPROM). This device exemplifies the critical role of small-footprint, non-volatile memory in modern design.

As a member of the extensively adopted 24LC series, this chip provides 128 bytes of byte-alterable memory, organized as a single block of 128 x 8. Its endurance is rated for 1,000,000 erase/write cycles, ensuring data integrity over the long operational life of a product. Furthermore, it guarantees data retention for over 200 years, making it a truly permanent storage solution for vital information.

The core of its functionality is the I²C (Inter-Integrated Circuit) serial interface. This two-wire protocol, comprising a bidirectional serial data line (SDA) and a serial clock line (SCL), drastically reduces the number of I/O pins required on a host microcontroller. This simplicity is a significant advantage, enabling efficient communication and simplifying PCB layout. The 24LC01BT-I/OT supports a 400 kHz clock frequency, allowing for reasonably fast data transfer for its intended applications.

Housed in a space-saving SOT-23-5 package, the device is ideal for compact and portable products. Its wide operating voltage range of 1.7V to 5.5V makes it exceptionally versatile, compatible with both modern low-voltage microcontrollers and legacy 5V systems. This broad voltage support is crucial for battery-powered applications where power efficiency is paramount.

Typical applications are vast and include storing:

User preference settings in consumer electronics.

Calibration data in industrial sensors and meters.

Network addresses and configuration parameters in IoT modules.

Data logging in portable medical devices.

ICGOODFIND: The Microchip 24LC01BT-I/OT remains a go-to choice for designers seeking a proven, ultra-compact, and highly reliable serial EEPROM. Its combination of a simple I²C interface, low power consumption, and robust data retention makes it an indispensable component for ensuring data persistence across countless electronic applications.
