The AT49BV002NT-12TC is a non-volatile memory designed for use in a wide variety of industrial and consumer applications. It is a type of Flash memory, which means that it can retain data even when power is lost. This makes it an ideal choice for industrial and consumer applications that require reliable storage of values and settings.

This memory chip is a CMOS NOR Flash memory, which is an Erasable Programmable Read-Only Memory (EPROM) type. It contains an 8-bit data bus, 512Kbits of memory, and 6,144 bytes of page sizes as well as an 8-bit address bus. The frequency of operation is typically 20MHz. The operating temperature range is from -40°C to 85°C while the storage temperature range is -55°C to 125°C.

The primary application field of the AT49BV002NT-12TC is for non-volatile data storage. This can be used, for example, for program memory for microcontrollers, or for storing configuration or calibration values for industrial equipment like motor controllers. It can also be used as a security code store or boot code store in secure systems. The chip has several additional features to support these applications, such as an Erase/Write lock, Byte write protection, and Sector protection.

The working principle behind this memory is fairly simple. There are two areas of memory - the Top memory, and the Bottom memory. The Top area of the memory is used to store user data, while the bottom half of the memory can be used for retaining system control information. To write or erase memory, a pulse is applied to one of the pins. The voltage is then reversed to the opposite polarity to indicate the desired write or erase operation.

The AT49BV002NT-12TC is a reliable, non-volatile memory solution for a wide range of industrial and consumer applications. It is designed for applications that require storing data even in the presence of power loss and has several features that make it suitable for secure systems. It is a simple CMOS NOR Flash memory with a typical operating frequency of 20MHz and an operating temperature range of -40°C to 85°C.
