The AT27LV520-90SC is a surface mount, 32-megabit non-volatile Flash memory module with a 25- to 90-ns access window. This type of memory module is highly sought after for embedded applications requiring a non-volatile, low power memory. It is also efficient for industrial and commercial applications where data protection is essential.

As a non-volatile memory module, the AT27LV520-90SC offers exceptional data protection and retention during any power interruption, making it ideal for applications requiring a high degree of data reliability. This module is designed to operate in temperatures ranging from -40 to +85 degrees celsius, and can be accessed quickly with a 25-90ns access window. Additionally, the module has an industry-leading error correction capability, excellent performance in small package sizes, and the ability to reliably store up to 32-megabits of data.

The AT27LV520-90SC utilizes a 4-bank, 32-megabit technology, allowing for fast parallel read and write functions. Each memory bank is 512 Kbits × 28 wide, containing 16K × 16 rows of data or 18K × 16 bits when the one-bit correction code is added. These two types of configurations allow a degree of flexibility, enabling the memory module to be used in a variety of applications.

The basic operation of this memory module is quite simple. On power up, the user writes the desired data to the module, and then reads the data back to ensure that it has been written correctly and completely. On power down, the data should remain intact and available on power up. To ensure that this happens, the AT27LV520-90SC uses two types of memory: volatile and non-volatile.

Volatile memory is lost on power down and is only used for buffering or transitory data or instructions. Non-Volatile memory, on the other hand, is designed to be written to and retained after power down, meaning any data or instructions stored there will remain in memory, even when the power is off. This type of memory is the key to the AT27LV520-90SC\'s ability to hold data even after power has been interrupted.

The AT27LV520-90SC is an ideal memory module for embedded applications requiring non-volatile memory. Its ability to reliably store 32-megabits of data, its industry leading error correction capability, and its fast 25-90ns access window allow it to be used in a wide variety of applications, ranging from industrial and commercial applications to automotive, medical, and military applications. Its small form factor makes it suitable for use even in the tightest spaces.
