Microchip 24CW320T-I/OT: A High-Performance 32-Kbit I²C Serial EEPROM for Modern Designs

The Microchip 24CW320T-I/OT is a 32-Kbit serial EEPROM designed for reliable non-volatile data storage in a wide range of applications. This device is organized as 4K x 8 and operates via the ubiquitous I²C (Inter-Integrated Circuit) protocol, making it an ideal choice for system designers seeking a simple, two-wire interface for communication with microcontrollers and processors.

A key feature of this EEPROM is its robust reliability and endurance. It is specified for 1 million erase/write cycles and offers data retention of over 200 years, ensuring long-term data integrity in demanding environments. Its wide voltage range (1.7V to 5.5V) allows it to operate seamlessly in both low-power and standard systems, from battery-powered IoT sensors to industrial automation controls.

The 24CW320T-I/OT includes several advanced features that enhance system design. It supports a 1 MHz clock frequency for fast data transfer. The device also incorporates hardware write-protection via a dedicated pin, safeguarding critical memory contents from accidental corruption. Furthermore, it offers four unique software-selectable I²C addresses, enabling up to four devices to share the same bus, thereby maximizing design flexibility without additional hardware.

Housed in a space-saving SOT-23-5 package, this EEPROM is perfectly suited for applications where board real estate is at a premium. It is extensively used in consumer electronics, automotive systems, smart meters, and medical devices for storing calibration data, user settings, and other crucial parameters.
