CY7C1021BNV33L-15ZXIT

The CY7C1021BNV33L-15ZXIT belongs to the class of memory. It functions as SRAM (Static Random Access Memory) to store information. For this reason, it is widely used in many applications.

This particular memory devide is a nonvolatile static RAM. This means that it retains all data stored in it when power is removed. It is available in the industry standard 800mil 28-pin plastic dual inline package. Its operating temperature range is -40°C to +85°C, and its storage temperature range is -55°C to +125°C.

The SRAM memories are asynchronous, and most importantly, there exists no need for any refresh circuitry, in comparison with the dynamic RAM (DRAM) memories. This makes it a more efficient and simpler circuit. The basic operation of the device is as follows. The data input can be written into memory either at the rising edge or falling edge of the clock. The sequence requires that the write enable line is first active, followed by the destination address and the data to be written. The CY7C1021BNV33L-15ZXIT consumes 60 mA of active power for the 155 MHz clock rate, and 0.1mA in standby mode.

Because of its nonvolatility and ease of use, this SRAM can be used in many applications. Examples include, but are not limited to: storage of critical control variables in controllers and wireless nodes and keeping active files in diskless personal computers, PC cards, and embedded systems. SRAM has become a critical component in many of the most popular applications since it is a perfect choice for synchronization purposes when compared to other volatile memories.

In conclusion, the CY7C1021BNV33L-15ZXIT is a nonvolatile static RAM. It is an asynchronous device, and requires no refresh circuitry. This makes it an efficient and simpler component for many applications, such as wireless nodes and diskless personal computers. It can be used for synchronization purposes as well, since it is a perfect choice for volatile memories.
