Working Principles

The CY7C4225V-15ASC operates based on the principles of static random access memory. It stores data in a volatile manner, meaning that the stored information is lost when power is removed. The chip utilizes a combination of transistors and capacitors to store and retrieve data quickly and efficiently.

When powered on, the chip initializes its internal circuitry and becomes ready to receive commands and data. The address inputs are used to specify the location in memory where data needs to be read from or written to. The control signals, such as Chip Enable (CE), Output Enable (OE), and Write Enable (WE), determine the type of operation to be performed.

During read operations, the requested data is retrieved from the specified memory location and made available on the data outputs. Conversely, during write operations, data provided on the data inputs is stored in the designated memory location.
