AT28HC256E-90TC is a type of memory chip used in a variety of electronic applications including electronic consumer products, industrial automation, medical equipment and vehicles. It has 256K bits (32K words) of non-volatile Electrically Erasable Programmable Read Only Memory (EEPROM). This chip is programmed and erased electrically with a suitable programmer or with an appropriate system of commands.

The AT28HC256E-90TC supports a wide range of applications that require non-volatile memory for data storage. It is often used for storing software, firmware, configuration data, and user data. Some examples of applications include mobile phones, automotive ECUs, home appliances, and security systems.

The main advantages of using the AT28HC256E-90TC memory chip are its low power consumption, fast speed, and high endurance. This chip consumes very little power, is extremely fast to write and erase data, and can handle up to 500,000 write/erase cycles. This makes it ideal for applications which require frequent data rewriting or updating, such as firmware and configuration updates.

The AT28HC256E-90TC is a 16-pin package memory chip. It is a non-volatile memory device, meaning that it will retain data even when not powered. The data stored in the chip is organized as 16-bit words, with each word occupying a unique address. It uses a two-wire serial interface to transfer data to and from the chip, and it also supports a parallel interface.

The AT28HC256E-90TC uses two distinct operating modes: a read mode and a write/erase mode. In the read mode, the chip will retrieve the 16-bit data stored at a given address. In the write/erase mode, data is written to the chip at a specified location, or erased from the chip.

To protect the data stored in the chip, the AT28HC256E-90TC has a range of security features. These include hardware write-protection, hardware or software erase-protection, hardware block-locking, and software bit-locking. Depending on the application, these features provide different levels of data security and control.

The AT28HC256E-90TC is a versatile and reliable memory chip, making it a popular choice for a wide range of applications. With its low power consumption, fast speed, and high endurance, this chip is suitable for applications that need frequent rewriting or updating. Moreover, its advanced security features allow for different levels of data protection and control, making it an ideal choice for data-sensitive applications.
