The AT28C256F-15SU memory is an integrated silicon memory device with a very high performance for applications that require large memory storage. It is a type of non-volatile memory, meaning that data stored in the memory will be retained when power is removed from the system. The main application areas of the AT28C256F-15SU memory are embedded systems, communication equipment, consumer electronics and automotive applications. The memory is also suitable for applications where there is limited access to power, such as portable devices.

The AT28C256F-15SU memory has a 256K x 8 organization, which means that it has 256K memory locations with 8 bits per location. Each location can store a single character of data (1-byte). The memory can be programmed using its serial interface, thereby allowing flexibility with regards to the programming tools and development hardware. The memory also features on-chip address and data registers, two control lines and two chip-enable inputs. This enables the memory to be connected to a variety of microprocessors, such as 8-bit and 16-bit.

The memory is powered by a single 3.3V DC supply, and has a maximum operating current of 40mA. The access time of a memory location is typically around 100ns. The memory is available in packages such as PLCC and TSSOP – this allows for flexibility in device placement and board design.

The working principle of the AT28C256F-15SU memory is relatively simple. For read operations, the memory’s address inputs will be provided with the address of the required memory location. The corresponding data is then output via the data output pins. For write operations, the required data is provided to the data input pins, and then the address inputs are used to specify the memory location where this data should be written to.

The AT28C256F-15SU is an efficient and robust memory device, with superior performance over other types of integrated memory devices. The memory has the capability to withstand low-voltage supply in the range of 2.0 to 3.6V. Furthermore, it has a temperature range from -40°C to +85°C, making it suitable for operation in extreme environmental conditions. This makes the memory an ideal option for a variety of applications where a reliable, efficient and cost-efficient memory solution is required.
