Cypress Semiconductor has unleashed a 72Mb video frame buffer device based on the company's SRAM technology, operating as a First-In, First-Out (FIFO) memory with independent read and write ports for fast data transfer. The CYFB0072 provides a simple SRAM-based interface that reduces implementation and debugging effort, improves time-to-market and reduces engineering costs, detailed the company.

The IC delivers enhanced signal integrity and operates at frequencies up to 133MHz with throughput up to 4.8Gb/s, commonly required for buffering video frames. With the ability to operate in any system that needs buffering at high speeds across different clock domains, the video frame buffers are suitable for a range of video and image processing applications, including picture-in-picture and interlacing in HD cameras, scan rate conversion in broadcast equipment, image scanning and enhancement in medical equipment, and radar and sonar in military systems.

The video frame buffer is configured in a bus width of 36 bits. Unlike DRAM-based buffer solutions, it operates in the industrial temperature range of -40°C to 85°C and does not require an external crystal. The device is available in low voltage complementary metal oxide semiconductor (LVCMOS), with the CYFB0072V33L device supporting 3.3V operation and the CYFB0072V18 device supporting 1.8V operation. It ships in a 14 x 22mm 209-ball BGA package.
