Memory is an important part in the computer system, which plays a vital role in storing and processing data. As an important area of integrated circuit manufacturing technology, memory chips are a key element in many applications. AT28HC256-12TI is one of these parts, which is widely used in different areas. Now let\'s have a look at its application field and working principle.

The AT28HC256-12TI is a high-performance 128k-bit EPROM (erasable programmable read-only memory). It includes 8,192 bytes of nonvolatile memory, organized as 32K words of 8 bits or 256K bytes. It can be used as a single chip in many consumer applications such as medical and consumer electronics, remote control systems etc. It is also widely used in automotive, industrial and telecommunications applications, where high speed with low power consumption is important.

The AT28HC256-12TI is designed to operate from a single 5V to 6V supply with proper handling of input and output signals. It has organized parameters and a wide operating current range which makes it an ideal choice for many applications.

In addition to its low power consumption, the AT28HC256-12TI has a variety of features that make it ideal for many applications. These features include an internal data retention stress timer, a "write cycle protective" function, and a fast random access time of 45ns.

The AT28HC256-12TI is a memory chip that relies on the piezo-electric principle to store data. It has an array of tiny pore-like structures on its surface that can respond to vibrations by storing these vibrations as charges. When these charges are then discharged, the data stored in the chip is retrieved. This is known as the piezoelectric effect, and it is the basis for the AT28HC256-12TI\'s function.

The AT28HC256-12TI also uses an Address Bus and Data Bus. These two busses work together to store and retrieve data from the chip. The Address Bus is used to identify which memory locations will be accessed. The Data Bus is used to store and retrieve data. The Data Bus also transfers data to other components in the system when needed.

The AT28HC256-12TI also uses a program counter, which is a special counter device that is used to keep track of which memory location is accessed. This counter is reset each time the memory chip is cleared, thus resetting the chip\'s contents.

Finally, the AT28HC256-12TI has a special write-enable line that allows the chip to store data into memory. This is done by applying a logic high to the write-enable line and a logic low to the chip enable line. This causes the counter to begin a write cycle and accept data from the Data Bus. The data is then stored into the corresponding memory location.

To sum up, the AT28HC256-12TI is a powerful and highly reliable EEPROM chip, which can be used in various applications. Its low power consumption, fast random-access time, and write-enable feature make it an ideal choice for many projects. Furthermore, its use of the piezo-electric principle and Address and Data busses allows it to store data reliably and quickly.
