ST95080W3 - 8 Kbit Serial SPI Bus EEPROM with High-Speed Clock

The ST95080W3 is a robust and reliable serial EEPROM memory chip designed by STMicroelectronics, a leader in the semiconductor industry. This device offers a storage capacity of 8 Kbits and utilizes the widely-accepted SPI (Serial Peripheral Interface) bus, ensuring compatibility with a vast array of microcontroller units and systems.

With its high-speed clock of 10 MHz (maximum), the ST95080W3 can perform write operations rapidly, making it an excellent choice for applications that require frequent data updates. It operates across a wide voltage range from 2.5V to 5.5V, providing flexibility in various power environments and making it suitable for both industrial and consumer applications.

The ST95080W3 boasts an endurance of 1 million write cycles and a data retention period of 40 years, which is a testament to its reliability and longevity. This ensures that data is preserved over an extended period, even under frequent write operations, making it an ideal solution for critical data storage in devices that need to operate over long periods without maintenance.

Additional features of the ST95080W3 include:

• Byte and Page Write (up to 32 bytes)
• Self-timed programming cycle with auto-erase
• Enhanced ESD protection
• Write protect of the whole memory array
• Sequential read operation

STMicroelectronics has also incorporated safety features into the ST95080W3, such as the Write Protect (WP) pin and software Write Protect, which prevent accidental overwrite or erasure of data. This makes it an excellent choice for applications where data integrity is paramount, such as in parameter storage, device configuration, and identification applications.

Developers can easily integrate the ST95080W3 into their designs, thanks to its industry-standard 8-pin package and the availability of comprehensive technical documentation and support from STMicroelectronics. Whether used in consumer electronics, automotive systems, or industrial controls, the ST95080W3 is a reliable and versatile EEPROM solution that provides secure and persistent data storage.
