The AT28HC256F-90SI is a type of static random access memory (SRAM) chip that is used for a number of different applications in computers and other electronic devices. It is designed to store data for a long period of time without the need for power. The AT28HC256F-90SI is composed of a number of individual memory cells arranged in an array, each capable of storing 256 bits of data.

Application Field

The AT28HC256F-90SI is used in a variety of applications. It is used in embedded systems, most commonly embedded microcontrollers, allowing them to store data without the use of external memory. It is also used in digital process controllers, in which it stores vital data and instructions on how to operate the system. AT28HC256F-90SI is also used on main memory boards in PCs, which allows the user to access frequently used data quickly.

Working Principle

The AT28HC256F-90SI utilizes the static random access memory (SRAM) technology, which is a type of memory that relies on the integration of flip flops. The memory cells, or flip flops, are connected to each other, and each one can hold 256 bit of data. This data can then be read from or written to the cell. The data stored in these cells will remain permanently until they are replaced with new data. The AT28HC256F-90SI comes in different sizes, and the capacity of memory is determined by the number of memory cells the chip has. The chip can store up to 4 kilobytes of data.

The operation of the AT28HC256F-90SI is determined by the use of a write enable signal (WE) and an address strobe signal. The write enable signal is used to control the writing of data on the memory cell, and the address strobe signal is used to specify the location of the data to be written. When the write enable and address strobe signals are both active, the data being sent to the memory cell will be written. The AT28HC256F-90SI also has a read enable signal (RE) that is used to control the reading of data from the cell.

The AT28HC256F-90SI has a low power consumption, which is beneficial for applications where power consumption is a concern. It is also easy to use, as the chip requires few external components. Furthermore, it has an extended temperature range, meaning that it can be used in a wide range of temperatures. This makes it an ideal choice for applications in all sorts of environments. Finally, the AT28HC256F-90SI is a reliable chip and can withstand shock and vibration, making it suitable for use in a variety of situations.
