FIFOs (First In, First Out) memories are widely used in digital systems. A FIFO is essentially a first in, first out memory buffer used to temporarily store either digital data, or data values derived from analog to digital conversion. The FIFO memory structure is essentially a First-In/First-Out double ended queue with the depth (or size) and width of the FIFO memory being determined by the design requirements. The actual size of the FIFO is determined by the length of the memory stack suitable for the application. The most commonly used FIFO sizes are 8k, 16k, 32k, 64k, 128k and 256k.One of the most popular FIFO memories is the 72V845L10PF from Silicon Storage Technology, Inc. (SST). The 72V845L10PF is a fully-realized, 512K-by-4FIFO having two separate input and two separate output ports. Each port is formed into two separate byte bidirectional data lines that interface directly with digital logic ICs or with any microprocessor. The individual byte bidirectional data lines are 4-bits wide, providing fast and efficient data streaming.In order to work, the 72V845L10PF FIFO memory must be initialized with a reset command. Once the reset command has been issued, the FIFO is ready to start operation. The application field and working principle of the SST 72V845L10PF can be determined by understanding its primary use and control logic.

The primary use for the SST 72V845L10PF is to stream data from one location to another through a high-speed bus. To facilitate this data transfer, the FIFO memory is configured to receive and write an 8-bit parallel word into the FIFO on each clock cycle. The data is clocked in from the data port onto the input port, and clocked out on the output from the FIFO memory, as illustrated in figure 1. The 72V845L10PF provides low data latency, high speed performance and a wide variety of protocol support.

The control logic of the 72V845L10PF FIFO memory is designed to manage data communication between the input and output ports. This is accomplished by monitoring the status of the two byte bidirectional data lines present the input and output ports, to ensure that the data is moved quickly and reliably. For example, when the “write enable” signal on the input port is set low, the data on the bus is transferred into the FIFO. When the “read enable” signal on the output port is set low, the data from inside the FIFO is transferred out of the memory onto the bus. When the input and output ports are enabled, the data is clocked in and out sequentially.

In addition to the “write enable” and “read enable” signals, the 72V845L10PF FIFO memory has several other control signals that can be used to configure the behavior of the 72V845L10PF. These control signals includes the reset signal, which is used to reset the FIFO memory, and the ‘write enable’, ‘read enable’, ‘underflow’, ‘overflow’, and ‘empty’ signals, which can be utilized to manage the data transfer.

The 72V845L10PF FIFO memory is designed to provide fast and efficient data streaming with minimal data latency. This makes it ideal for applications where data needs to be transferred quickly and reliably, such as video streaming and audio streaming. In addition, the 72V845L10PF FIFO memory is compatible with multiple protocols and provides a wide variety of protocol support.

The 72V845L10PF FIFO memory from Silicon Storage Technology, Inc. (SST) is a fully-realized, high speed memory stack which provides efficient data streaming with minimal latency. It is ideal for applications which require fast and reliable data transfer such as video streaming, audio streaming and other applications where data movement is frequent. The 72V845L10PF FIFO memory is designed with numerous control signals, including ‘write enable’, ‘read enable’, ‘reset’, ‘underflow’, ‘overflow’, and ‘empty’ signals that can be utilized to manage the data transfer.
