Winbond has added to its SPI NOR Flash portfolio with a monolithic 1.8V 512Mb SPI NOR flash that can support up to 166 MHz standard/dual/quad SPI clocks.
Apart from the existing 3V 512Mb W25Q512JV, the new 1.8V W25Q512NW SPI NOR Flash also features pin-to-pin compatibility, enabling customers to upgrade to higher flash storage capacities without having to change the footprint of their designs.
This enables them to extend the life of their products, speed time to market, and save development time and effort by having one single flash platform that can be used across their future product roadmap.
W25Q512NW can support up to 166 MHz SDR and 80MHz DDR in high read-speed, it can achieve high performance on XIP (eXecute In Place) and Instant-on with QPI.
The chip can also be stacked to 1Gb and 2Gb, which gives designers more flexibility to extend the density up to 2Gb and better performance on Read-While-Write. For example, the two-die device will support Read While Write operation for OTA updating without suspension of read operations and with no risk of losing the existing firmware image in the event of an unexpected power interruption, providing fast and stable live OTA (Over-The-Air) system firmware update.
This compatibility is useful for customers designing applications such as 5G modem, 5G edge computing, cloud server, fiber optic modems, and smart IoT segments where they typically increase code-storage flash density 2X every 2 years.
This also helps the OEM software teams to develop application-code well-suited for new code releases with multiple new feature-set without compromising on Code Storage Flash Memory density limitations.
