The drawback of flash memory technology is that program and erase speeds are much slower than read speeds. During these slow operations, the ability to read from the memory is blocked, choking system performance. RWW removes system bottlenecks by allowing concurrent operations. Without integrated RWW, multiple devices and CPU resources are required to achieve the same functionality, leading to increased system complexity, cost and power.

Performance for the real worldThe continual evolution of internet of things (IoT) and smart devices is driving the need for increased intelligence at the edge as well as liquid-smooth graphical user interfaces (GUIs), all while keeping power consumption to a minimum. A key component of system design to meet these demands is the selection of the right non-volatile memory. EcoXiP is specifically targeted to help system designers attain more processing power and reduce system power consumption.
EcoXiP’s blazingly fast octal xSPI interface and low-power operation offer rapid data transfer which is ideal for fast boot, graphical user interface (GUI), artificial intelligence (AI), and execute in place applications. The power efficiency of EcoXiP is so exceptional that it can outperform traditional quad SPI devices for the same data throughput. This makes EcoXiP the perfect choice for power- conscious or battery-operated designs.
Unlike other octal devices, EcoXiP is specifically designed to work with cache controllers, dramatically reducing latency for cache misses. With its high performance, even time-critical code can execute directly out of flash, eliminating the need to add expensive and power-hungry external DRAM. EcoXiP’s high-speed and power-efficient design provides an ideal solution for memory expansion in systems that don’t have enough embedded flash or SRAM.
