HD FIFO Targets Video and Imaging Applications

Cypress has launched First-In, First-Out (FIFO) memories with densities up to 72Mbit for video and imaging applications that require high density and high frequency for effective buffering. The HD FIFO is an advanced buffering alternative to standard synchronous DRAM memories used in combination with large FPGAs. Cypress's HD FIFOs offer enhanced signal integrity compared to a DRAM-based solution and operate at a 133MHz frequency, which is suited for buffering video frames.

The HD FIFO offers up to eight separate directly addressable queues to enable designers to stream multiple video channels simultaneously. Using an HD FIFO enables designers to use a smaller FPGA, resulting in overall system-cost reduction. Cypress's HD FIFO also reduces design complexity, speeding time-to-market for video and imaging systems in broadcast, military, medical and BTS segments.

The new HD FIFOs are available in 18-, 36- and 72Mbit densities. They support multiple I/O standards, including 3.3 and 1.8V LVCMOS and HSTL1. The HD FIFO solution also provides user-selectable memory organisation and can be configured as a x9, x12, x16, x18, x20, x24, x32 or x36 device, providing designers flexibility to choose optimal depth and width. All of the HD FIFO densities are offered in the 209-ball BGA package, which ensures scalability.
