Spansion Inc. has released a series of serial peripheral interface (SPI) flash memory that the company said features the industry's highest read performance and smallest package footprint addressing the needs of graphics-rich applications such as automotive instrument clusters and industrial human machine interfaces. The Spansion FL Dual-Quad SPI family claims to deliver fast boot times and code execution, and quick graphic performance with 160MB/s read throughput, a 240 percent improvement over the fastest alternative SPI solutions, boasted the firm.

Automotive electronics, home and industrial controls, and high performance consumer applications are using more sophisticated graphical user interfaces to enhance and simplify the interaction between the user and the machine. This trend is resulting in higher-resolution images, animations and even video. To meet these higher demands for read throughput, engineers commonly use two double data rate (DDR) quad-I/O SPI flash memory devices in parallel to achieve maximum read throughput, leading to an increase in board space and more complex designs. Spansion FL Dual-Quad SPI flash memory simplifies the design with a single device, achieving the same performance using a single space-saving, secure BGA package, the company stated.

The Spansion FL Dual-Quad family is a 3V multi-I/O (single, dual, quad and dual-quad-I/O) DDR serial flash memory available in 256Mb and 512Mb densities and packaged in an industry standard 8 x 6mm 24-ball BGA. The universal foot print supports current Quad SPI, Dual-Quad SPI as well as next generation higher-speed Flash memories. Both industrial and automotive in-cabin temperature ranges are offered. The family will sample in 1Q14 with production in 2Q14.
