AT28HC256-90FM/883, is a 8-pin MOS memory chip that is sold as an electrically erasable programmable read-only memory (EEPROM). It can be used in many applications, such as automotive, industrial and medical, and is often used for low-frequency, low-power applications. It has a range of frequency of 10 to 30MHz and is rated for operation at 3.3V or 5V.

Application Field

The AT28HC256-90FM/883 EEPROM can be used in a wide range of applications. One of the primary uses is as a controller, allowing developers to create low-power, low-frequency applications. It is especially suited for automotive, industrial and medical applications. It has a large address range, allowing up to 256K bytes. This makes it a great choice for storing datasheets, image files and other large pieces of data. It is also used often in low-voltage, low-current operations, such as those found in remote control systems, satellites and navigation systems.

Working Principle

The AT28HC256-90FM/883 EEPROM works by storing data in its electrically erasable programmable read-only memory (EEPROM). This is a type of non-volatile memory (NVRAM) that is capable of holding data even when no power is applied. Data is written to the memory by applying a voltage across write gates and read out using address lines. In order to erase data, a voltage pulse is applied to the erase gate. The chip is designed to use flash technology which means that it is unharmed by shock and vibration, so it can be used in a wide variety of environments.

Conclusion

The AT28HC256-90FM/883 EEPROM is a versatile and reliable device for use in low-power, low-voltage operations. It is commonly found in automotive, industrial and medical applications, and offers users a low-frequency, high-address range for storing data. It is easy to use and can be erased and re-programmed over and over again. It is an excellent choice for developers who need a reliable and versatile memory chip.
