AT25160B-XHL-T: 16-Mbit SPI Serial EEPROM for Robust Industrial Data Storage

In the demanding world of industrial electronics, where operational environments are characterized by extreme temperatures, voltage fluctuations, and constant vibration, the need for highly reliable non-volatile memory is paramount. The AT25160B-XHL-T, a 16-megabit Serial Peripheral Interface (SPI) Serial EEPROM, is engineered specifically to meet these rigorous challenges, providing a robust and dependable solution for critical data storage.

This memory IC stands out through its exceptional endurance and data retention capabilities. It supports a minimum of 4 million write cycles per sector, ensuring that data can be updated frequently over the extended lifespan of industrial equipment. Furthermore, it guarantees data integrity for over 100 years, safeguarding parameters, calibration data, and event logs against loss.

A key feature of the AT25160B-XHL-T is its advanced SPI interface, which supports clock frequencies up to 85 MHz. This high-speed communication is essential for applications requiring rapid data logging or quick access to configuration settings, minimizing wait states for the host microcontroller and improving overall system responsiveness. The interface is compatible with both Mode 0 and Mode 3 operations, offering design flexibility.

To ensure unwavering performance in harsh conditions, the device operates across an extended industrial temperature range from -40°C to +85°C. This makes it suitable for applications in factory automation, automotive systems, smart grid infrastructure, and outdoor instrumentation, where ambient temperatures can swing dramatically. Its high reliability is further reinforced by its strong immunity to electrical noise.

The memory is organized as 2,048,256 x 8 bits and features a flexible page structure. It includes vital hardware protection mechanisms with a write-protect pin (WP) and software protection features, allowing sectors of the memory array to be locked against accidental or malicious writes. This is critical for protecting firmware and essential configuration data from corruption.
