WinBond Electronics launched a new ultra-low power 64Mb 1.2V SPI NOR Flash

     WinBond announced the launch of a new SpiFlash product, W25Q64NE, expanding the 1.2V SPI NOR Flash capacity to 64Mb for the first time. Huabang's new W25Q64NE flash memory can provide more code storage space and reduce the operating power consumption of the device, fully meeting the memory requirements of the new generation of intelligent wearable devices and mobile devices.

     The extended range of working voltage of the product is 1.14V-1.6V, which is compatible with the output voltage of a single AA alkaline battery. This time, the product capacity is increased to 64Mb. Huabang 1.2V NOR Flash series products can meet the higher requirements for code storage space of intelligent devices. At present, the new W25Q64NE products have been sent samples, and the USON8-3x4 and WLCSP small size packages that meet the industry standards are provided.

     Generally, 99% of the total power consumption of mobile devices and wearable devices is generated in the operating mode. Compared with 1.8V SpiFlash products, Huabang 1.2V SPI NOR Flash can reduce the operating power consumption of Flash by one third. Therefore, the use of Huabang's 1.2V NOR Flash can help the devices with small battery capacity, such as TWS earphones and fitness bracelets, greatly extend the product life.

     WinBond said: "Today, battery life has become a key factor influencing consumers to buy new products such as TWS earphones and smart watches. Huabang's new W25Q64NE flash memory is the ideal choice for these device manufacturers, which can help improve the competitiveness of terminal products."

     In the reading mode with the operating frequency of 50MHz, the working current of 1.8V SpiFlash memory is 4mA, and the power consumption is 7.2mW. At 50MHz, the working current of Huabang 1.2V SpiFlash memory is also 4mA, but the power consumption is only 4.8mW. Replacing the 1.8V product with 1.2V SpiFlash can save 33% of power consumption immediately.

     In addition to saving power, 1.2V SpiFlash simplifies system design and reduces costs. With the development of SoC technology towards more advanced manufacturing processes, the I/O voltage of the new generation of SoC is gradually decreasing, which is now lower than 1.8V. Therefore, a level converter is required to connect with the traditional 1.8V/3V SPI Flash, which will lead to additional costs and increase the complexity of system design. With 1.2V flash memory, SoC can be directly connected to SPI Flash without level converter, thus reducing BOM cost and PCB space.

     WinBond W25Q64NE is equipped with standard SPI NOR interface with excellent performance, and the maximum data transmission rate can reach 42MB/s. The architecture of 1.8V/3V SPI Flash is the same as that of 1.8V/3V SPI Flash. It supports a minimum of 4KB erasable sector.
