Cypress Semiconductor has introduced the CYFB0072 video frame buffer, which is a 72Mbit device leveraging on the SRAM technology and operating as a First-In, First-Out (FIFO) memory with independent read and write ports for fast data transfer. The product allows for improved signal integrity and operates at frequencies up to 133MHz, with throughput up to 4.8Gbit/s.

The video frame buffer provides a simple SRAM-based interface that reduces implementation and debugging effort, improves time-to-market, and reduces engineering costs. The IC delivers enhanced signal integrity and operates at frequencies up to 133MHz with throughput up to 4.8Gbit/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 wide 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 72Mbit video frame buffer is configured in a bus width of 36bits. Unlike DRAM-based buffer solutions, it operates in the industrial temperature range of -40 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 14x22mm 209-ball BGA package.
