CY7C4251-15JXC

The CY7C4251-15JXC is a low-skew, high-speed FIFO memory IC. It is designed to store data in a high-performance register, improving overall memory bandwidth, removing the need for complex multiplexers, and providing enhanced control of the pipeline data flow. This IC is suitable for a variety of applications, such as networking, storage, and embedded system applications.

The CY7C4251-15JXC is mainly used for applications requiring high data bandwidth and/or high data throughput, such as networking, storage, and embedded microcontroller systems. It is well suited for high-performance systems that require a faster interface than FPGAs can realistically provide. Additionally, this device’s output is asynchronous, allowing the user to match the speed of their external memory with the speed of the CY7C4251-15JXC.

The device is also useful in applications where the pipeline has multiple sources, such as when data must be read from multiple memories. By using the CY7C4251-15JXC, data can be read from all of the memories simultaneously, with each memory’s data output acting as an input to the register. This eliminates the need for multiplexers, and as a result, reduces power consumption and improves overall performance.

The CY7C4251-15JXC is a register-based FIFO memory that stores data in a high-speed pipeline. It consists of a 256-bit dual-port pipelined register (Register I/O) and a 32-bit RAM array (RAM I/O). A single clock runs the entire FIFO, allowing data to be read out of the register as fast as it is written in. This is possible since the register is double clocked (on both the rising and falling clock edge), and the RAM array is single clocked (on the rising clock edge).

When data is written into the FIFO, it is first stored in the RAM array. The FIFO controller then reads the data from the RAM array, stores it in the register, and shifts the register contents to the output port. Meanwhile, the new data from the RAM is loaded into the register. This effectively doubles the data bandwidth. In addition, the CY7C4251-15JXC supports a data-valid signal that is asserted for each word transferred, allowing the user to synchronize the output data with external logic.

The CY7C4251-15JXC is a low-skew, high-speed FIFO memory IC designed to improve overall memory bandwidth and provide enhanced control of the pipeline data flow. It is suitable for a variety of applications, including networking, storage and embedded microcontroller systems, and can be used to simplify complex multiplexers. In addition, its asynchronous data output allows the user to match the speed of their external memory with the CY7C4251-15JXC. As a result, the device provides an efficient and high-performance solution for a wide range of applications.
