Microchip Technology's 25LC256T-E/SN Serial EEPROM

The 25LC256T-E/SN is a high-performance 256Kb serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from the renowned manufacturer, Microchip Technology. This EEPROM is part of the 25XX series, which is designed for a wide range of applications that require reliable and durable non-volatile memory storage. The 25LC256T-E/SN offers a flexible and convenient solution for data storage in industrial, automotive, and consumer electronics.

One of the key features of the 25LC256T-E/SN is its SPI (Serial Peripheral Interface) bus compatibility, which allows for high-speed data transfer and simple integration with most microcontrollers. The device operates at a voltage range of 2.5V to 5.5V, making it suitable for various operating environments and ensuring compatibility with both 3.3V and 5V systems.

The 25LC256T-E/SN has a 64-byte page write buffer, which makes it ideal for writing large amounts of data efficiently. The device also supports a maximum clock frequency of 10 MHz, enabling rapid read and write operations, which is crucial for applications that require quick data access and manipulation.

Safety and data integrity are paramount, and the 25LC256T-E/SN addresses these concerns with its write-protect feature. This feature prevents accidental overwrites and data corruption, thereby ensuring the safety of critical data. Additionally, the device has an endurance of 1 million erase/write cycles and a data retention period of over 200 years, offering exceptional reliability and stability over an extended period.

The 25LC256T-E/SN comes in an 8-pin SOIC (Small Outline Integrated Circuit) package, which is known for its compact footprint. This makes the EEPROM an excellent choice for space-constrained applications where board real estate is at a premium.

In summary, the 25LC256T-E/SN EEPROM from Microchip Technology is a versatile, reliable, and high-speed memory solution suitable for a broad array of applications. Its robust feature set, including SPI interface, large page write buffer, and long-term data retention, make it an essential component for designers and engineers looking to incorporate non-volatile memory into their systems.
