Microchip Technology's 24FC256-I/MF EEPROM

The 24FC256-I/MF is a high-performance, 256-kilobit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology. It is designed to deliver a flexible and robust data storage solution for advanced microcontroller-based systems. This EEPROM operates on the I²C bus interface, which ensures easy integration into existing designs due to its widespread adoption and support.

With a memory density of 256Kb, the 24FC256-I/MF offers ample space for storing configuration settings, device parameters, or small application datasets. It supports a wide voltage range from 2.5V to 5.5V, making it suitable for various applications that may require low-power operation or compatibility with higher voltage logic levels.

The device comes in a compact 8-lead SOIJ package, denoted by the suffix 'MF', which is ideal for space-constrained applications. Furthermore, its industrial temperature range of -40°C to +85°C ensures reliable operation under extreme environmental conditions, making it an excellent choice for industrial, automotive, and outdoor applications.

Key features of the 24FC256-I/MF include:

• High-Speed I²C Interface: It supports standard, fast, and fast-plus I²C protocols, with clock frequencies up to 1 MHz, enabling quick data access and efficient communication with microcontrollers.
• Write-Protect Feature: A hardware write-protect pin provides protection against inadvertent writes, ensuring data integrity during critical operations or after deployment.
• Page Write Buffer: The device can write up to 64 bytes in a single transaction, which enhances write operations and helps to optimize system performance.
• Sequential Read: The sequential read function allows for the reading of the entire memory array with a single command, making data retrieval simple and efficient.
• Long Data Retention: Data retention is rated for over 200 years, and the device is capable of 1 million erase/write cycles, ensuring the longevity and durability of the stored data.
• ESD Protection: The 24FC256-I/MF is designed with input protection to withstand Electrostatic Discharge (ESD) events, enhancing the reliability of the product in sensitive applications.

This EEPROM is a perfect solution for applications requiring non-volatile memory storage, such as configuration parameters, device calibration data, or small user applications. The 24FC256-I/MF from Microchip Technology is a testament to the company's commitment to providing high-quality, reliable memory solutions for the electronics industry.
