AT28HC256-12TC

The AT28HC256-12TC is a memory component designed and manufactured by Atmel Corporation that provides its users with the ability to store data. It is a 2K x 8-bit Electrically Erasable Programmable Read Only Memory (EEPROM). This component operates from a single +5V DC power supply, and comes in an easy to use 16-pin DIP, allowing it to be conveniently mounted on any board or system.

The main application field for the AT28HC256-12TC is in system memories and microprocessors. It is a nonvolatile memory, meaning it can keep data stored even when power is removed or the device itself is turned off. This makes it perfect for applications where data needs to be stored infinitely without being lost or compromised. It is also ideal for applications where an update or modification to stored data by the user is required without any danger of becoming corrupt or lost.

The AT28HC256-12TC has a three-state output which enables the user to connect multiple devices concurrently. It also has the ability to perform random read and writing operations in fewer steps than with other memory components. In addition, it features a single 5V DC power supply for operation, making it a great choice for applications in a power-sensitive environment.

The working principle of the AT28HC256-12TC is fairly simple. The device stores data electromagnetically in a grid pattern consisting of memory cells, each one capable of storing either a 0 or a 1. Each of these cells has an electrically chargeable floating gate which enables the user to write and erase the contents of each cell. The physical process generally involves passing electrons through the cell directly and implanting the required charge.

The AT28HC256-12TC employs a rather sophisticated architecture in order to provide performance. It consists of a select bank and array of eight parallel registers. The select bank is used to address the particular memory cell or register under writing or reading operations. When a write cycle is activated, the eight parallel registers are filled with the data to be written. The data is then transmitted to the memory cells or registers, and the registers are cleared. When a read cycle is activated, the registers receive the data from the memory cells, and the data is then transferred to the system.

The AT28HC256-12TC is a versatile and powerful memory component that is perfect for many applications. It is easy to use, and its features and capabilities make it an ideal choice for embedded systems and other applications that require data storage.
