Memory is an electronic component that can store data. One type of Memory is the AT28HC256E-12DM/883. This Memory is an 8-bit Electrically Erasable Programmable Read-Only Memory (EEPROM). It is a non-volatile memory that can be used to store data in different applications.

Application Field

The AT28HC256E-12DM/883 is used for data storage in a wide range of applications. This includes automotive, consumer electronics, industrial, appliance control, medical and other markets. The Memory is suitable for memory applications requiring security, reliability and long shelf-life. It is particularly useful for storing data that needs to be retained over power cycles or during times of inactivity.

The Memory offers 256k-bits of memory and is available in an industrial temperature range of -40°C to +85°C. It is available in different package styles including SOIC, Plastic Dual-In-Line Package (PDIP) and TSSOP. It is also available in three speed grades. This allows it to be used in a variety of applications that require a particular speed.

Working Principle

The AT28HC256E-12DM/883 is a non-volatile memory. This means that the data stored in it is retained even when power is removed from the device. This is accomplished by a mechanism called “floating gate technology” in which two transistors are used. One transistor has a virtual floating gate that stores the electrical charge, while the other write and access the charge.

The Memory is organized into blocks of 8K x 8-bit words. It features an auto-write capability that simplifies the programming process and provides faster write throughput. The Memory can also be accessed using a standard parallel port interface. It is also pin-compatible with other similar EEPROM devices, allowing simple drop-in replacement.

The AT28HC256E-12DM/883 also features data protection and security features. Data protection is accomplished using write-protection and read-protection bits. It also supports data encryption using a secure key. This ensures that the data stored in the Memory can only be accessed with authorized access.

The AT28HC256E-12DM/883 is an ideal choice for applications that require reliable, secure and long-term data storage. It is available in various package styles and supports a wide operating temperature range, making it suitable for a variety of applications.
