72220L10TPG Application Field and Working Principle

Introduction

• 72220L10TPG is a family of high-performance, low-power FIFO (first-in, first-out) static random access memory (SRAM) devices.These devices feature two independent FIFO arrays, configurable to either 8K-deep FIFO or 8K × 8-bits deep. In addition, a state-of-the-art pipelined architecture is implemented to minimize latency and maximize performance while consuming less power than competing SRAM-based FIFOs.

Logic – FIFOs Memory

• FIFO (first-in, first out) memories are designed to store data in a first-in, first-out manner. This type of memory is characterized by sequence related storage and retrieval of data elements, and is thus ideal for many applications where data is required to be stored and later retrieved in the same order as it was stored.

Application Field

• 72220L10TPG can be used in many applications such as imaging, video, medical and automotive systems. For example, in high-definition video applications, where a large amount of data needs to be stored and retrieved in the right order, the 72220L10TPG offers an ideal solution. It also features an automatic flow-through interface, which allows data to be efficiently written to and read from the FIFO.

Typical Features

• The features of the 72220L10TPG FIFO family include low-power operation, small footprint devices, 16 384 words by 8 bits of storage capacity, variable read/write port sizes, two independent FIFO data pointers, independent FIFO ports, prioritized read and write operations, standard data erase operation, wide input/output-level compatibility, automatic flow-through interface and more.

Working Principle

• The working principle of the 72220L10TPG FIFO is straightforward: data is written to the FIFO in a sequential manner, starting from the first location. Each write operation moves the data pointer forward, and subsequent reads are performed wave-after-wave in the same order. This process continues until all data is read out, at which point the data pointers are reset back to the first location. In addition, the 72220L10TPG FIFO uses special pump logic to minimize the latency for read and write operations.

Conclusion

• The 72220L10TPG FIFO is a powerful and efficient static random access memory device designed for applications that require high-performance, low-power operation. It features two independent FIFO arrays, configurable to either 8K-deep FIFO or 8K × 8-bits deep, and utilizes a state-of-the-art pipelined architecture to minimize latency and maximize performance while consuming less power than competing SRAM-based FIFOs.
