Microchip Technology AT24C256BW-SH-B EEPROM

The AT24C256BW-SH-B is a high-performance 256Kb I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) device from Microchip Technology, designed for data storage that necessitates low-power and reliable non-volatile memory. Its 256-kilobit capacity is organized as 32,768 words of 8 bits each, making it an excellent choice for a wide range of applications that require data storage or device configuration settings that must be preserved during power-off scenarios.

This EEPROM operates from a single power supply with a voltage range of 2.5V to 5.5V, making it versatile for various system designs. It is particularly well-suited for battery-operated devices due to its low power consumption. The AT24C256BW-SH-B offers a fast I2C bus interface with speeds up to 1 MHz, allowing for quick and efficient data transfer between the memory and the host controller.

The AT24C256BW-SH-B features a hardware write protect pin, which provides an additional layer of security by preventing unintended writes to the memory. This is particularly useful in applications where data integrity is critical. Additionally, the device supports both byte and page write modes, enabling flexible programming options for different use cases.

One of the key benefits of this EEPROM is its high endurance, with a guaranteed 1 million write cycles and a data retention period of over 100 years. This ensures that data stored on the device will remain secure and uncorrupted over an extended period, even under frequent write operations.

The compact 8-lead SOIC package allows for easy integration into space-constrained designs, making the AT24C256BW-SH-B a practical choice for embedded systems, industrial controls, smart cards, and many other applications that require dependable and long-lasting non-volatile memory storage.

Overall, the AT24C256BW-SH-B from Microchip Technology is a robust, reliable, and versatile EEPROM solution that provides designers with a secure and efficient way to store critical data in a variety of electronic products.
