Winbond Electronics, the world's leading supplier of semiconductor memory solutions, announced today, June 17, 2021, a single-die monolithic 1.8V 512Mbit SPI NOR flash that supports single/dual/quad SPI clocked up to 166MHz. announced that it will expand its total solution for SPI NOR Flash.

In addition to the existing 3V 512Mbit W25Q512JV, this new 1.8V W25Q512NW SPI NOR flash also offers pin compatibility, allowing customers to move to higher capacity flash storage without changing the board footprint. You can upgrade. This allows customers to secure a single flash platform for longer product life, faster time to market, and reduced development time and effort.

- Pin compatibility allows code storage flash capacity to be scaled without changing footprint between different hardware platforms

Selectable from minimum 16Mbit to maximum 2Gbit

The new single-die NOR flash W25Q512NW has already been adopted by customers in various countries and has started small-lot production, with mass production planned for the second half of 2021.

●Leveraging Winbond's in-house design and manufacturing capabilities, we are committed to mass supply and continuous support to customers around the world.

Winbond said: “Emerging 5G applications require high quality and high density SPI NOR Flash. the Company SPI NOR Flash W25Q512NW not only meets all these requirements, but also It's a compatible and backward compatible solution."

■ Advantages of W25Q512NW

The W25Q512NW supports high-speed reading of SDR up to 166MHz and DDR of 80MHz, and can realize XIP (eXecute In Place) and fast boot by QPI mode. In addition, the capacity can be expanded up to 2 Gbit by stacking die, and the read-while-write function of the die stack product improves performance. The 2-die stack product enables write operations during OTA (Over-The-Air) without interrupting read operations, and with the existing firmware unchanged, even in the event of an unexpected power outage. , provides fast and stable system firmware updates.

■ Target application of W25Q512NW

The compatibility of W25Q512NW with existing products, such as 5G modems, 5G computing, cloud servers, optical fiber modems, smart IoT, etc., is designed so that the flash capacity for code storage doubles every two years. For existing customers, this is a breakthrough. It also enables your software development team to develop products with multiple new feature sets as the maximum capacity of compatible flash memory for code storage increases.
