AT28HC256-12TU

Generally speaking, memory devices are mainly used for storing data, for instance, the AT28HC256-12TU can be used for the same purpose. In this article, its application fields and working principles will be described in detail.

Types of Memory

As there are different types of memory available in the market, the AT28HC256-12TU is a type of EEPROM or Electrically-Erasable Programmable Read-Only Memory. The main features that differentiate it from other types of memory are the fact that it can be re-programmed through the use of electrical pulses.

AT28HC256-12TU Application Fields

The AT28HC256-12TU is mainly used in Industrial Controls and Automotive Applications. It is also used in Medical and Commercial Applications as well.

• Industrial Controls: The AT28HC256-12TU is commonly used to store data and parameters of their tasks such as pressure measurements, motor speed and torque control.
• Automotive Applications: The AT28HC256-12TU can be used for the Automotive industry to store information about engine management systems and vehicle security systems.
• Medical Applications: The AT28HC256-12TU can be used to store patient information and maintain records accurately.
• Commercial Applications: The AT28HC256-12TU can be used in Point Of Sale (POS) systems, cash registers and various other data storing systems.

AT28HC256-12TU Work Principle

The AT28HC256-12TU is an EEPROM device with an organized structure. Its internal construction includes a number of EEPROM cells, usually organized as an array of rows and columns, and a number of decoders and logic circuits which are used to control signal paths for addressing and reading and writing data in the EEPROM cells.

When a signal is applied to the chip, the data in the EEPROM cells is read or written. Each EEPROM cell contains two components, namely a floating-gate transistor, which stores the data, and a control gate which is used to control the reading and writing operations.

For reading purposes, the signal is applied to the control gate, which then in turn read out the data stored in the floating-gate transistor. For writing purposes, the signal is applied to the control gate and the data is then written into the floating-gate transistor.

Conclusion

To conclude, the AT28HC256-12TU is an EEPROM device with a wide range of applications in industrial, automotive, medical and commercial fields as it is able to store data and parameters accurately and reliably. Its internal structure and working principles have also been described in this article.
