In addition, Gigadevice ranks third in NOR Flash revenue, with capabilities in R&D, production, and sales of NOR-related products. For specific details, see the table below.

Winbond provides serial flash products with densities ranging from 512KB to 256Mb in 8-pin SOP (150mil, 200mil) or 16-pin SOP (300mil) packages. These devices, organized in X1, support read, erase, and program operations. These products use the Serial Peripheral Interface (SPI) protocol. Winbond’s serial flash not only benefits the hardware configuration of systems but also reduces the complexity of system design. Our operation voltage range is from 2.7V to 3.6V for 3V products. All products are currently available from 512KB to 256Mb.
In addition, Winbond offers high-performance serial flash products with dual I/O and quad I/O operations, achieving double and quadruple reading performance up to 300Mbits/second for high-end consumer applications. Triggered on the rising and falling edges of the clock, the DTR (Dual Transfer Rate) mode further enhances the reading speed to 400Mbits/second. Multiple I/O products provide capacities of 8MB and above. Winbond also offers a range of low-voltage, 1.8V and 2.5V dual I/O and quad I/O interface serial flash products.
Winbond provides a wide range of industry-standard parallel flash memory products with 3V, 1.8V, and 5V operating voltages, ranging from 2Mb to 1Gb in density. These products have boot and unified sector architectures in x8, x16, and x8/x16 optional configurations. Winbond flash memory provides customers with cost-effective, high-performance, and reliable products, offering low power consumption, high durability, and reliability.
Winbond’s 3V parallel flash products are available in two versions: MX29LV series (standard read access) and MX29GL MX68GL series (page mode access). Winbond also offers 1.8V parallel flash products: MX29SL (standard access), MX29NS (burst mode, AD-MUX), and MX29VS (burst mode, synchronous read/write, AD-MUX).
Providing 8-bit, 16-bit, and 8-bit/16-bit selectable data transfer modes. Power supply voltages are 5V, 3V, and 1.8V. The MX29GL series offers advanced page mode interfaces optimized for read access and programming operations, allowing users to continuously read multiple data using page mode.
Winbond has launched a low-voltage 1.2V NOR Flash that supports the latest industry standards and can support dual, quad SPI, and Quad Peripheral Interface (QPI). The W25QxxND 1.2V series products have comparable operational performance to existing 3V and 1.8V flash products, and can further save power consumption. For battery-powered devices with limited design space, such as mobile devices, IoT, and wearable devices, and for flash memory requiring low power consumption, the W25QxxND 1.2V series products offer 2mm x 3mm USON8, narrow 150mil SOP8, 6x5mm WSON 8-pin packages, and KGD (Known Good Die). The 1.2V series products can operate up to 1.5V, using a single dry battery, unlike typical designs that require two batteries in series for 3V operation.
Winbond’s W25X and W25Q SpiFlash® Multi-I/O memory support the universal SPI interface, with capacities ranging from 512Kb to 512Mb, featuring small capacity erasable blocks and industry-leading operational performance. The W25X series supports Dual-SPI dual-line output mode, effectively doubling the operational frequency of the standard SPI.
The W25X series supports Dual-SPI dual-line output mode, effectively doubling the operational frequency of the standard SPI. The W25Q series is an advanced version of the 25X series, supporting Quad-I/O SPI four-line output mode, providing higher performance with an operational frequency of 104MHz equivalent to 416MHz (50M-Byte/S transfer rate), which is four times the performance of standard single-line SPI operations. The W25Q series not only outperforms parallel flash but also offers packages with fewer pins.
Faster transfer rates mean that the controller can directly execute in place (XIP) with the flash memory through the SPI interface or accelerate copying code to RAM, speeding up boot times. In addition, some SpiFlash® support QPI (Quad Peripheral Interface) for faster instruction set transmission, enhancing XIP transfer efficiency. Additionally, smaller packages are more conducive to applications in handheld and mobile devices with limited design space.
Wuhan Xinxin has launched the 50nm Floating Gate process SPI NOR Flash wide voltage product series XM25QWxxC. This product series supports low-power wide voltage operating ranges, suitable for IoT, wearable devices, and other power-sensitive application product design solutions.
The XM25QWxxC series products can achieve read speeds of up to 108MHz across a voltage range of 1.65V to 3.6V (supported in all single/dual/quad channel and QPI modes), providing faster and stronger performance than other suppliers, with no clock speed reduction after the power supply voltage drops. Its transmission rate outperforms 8-bit and 16-bit parallel flash. In continuous read mode, high-efficiency memory access can be achieved, requiring only 8 clock instruction cycles to read a 24-bit address, thus enabling true XIP (execute in place) operations.
The XM25QWxxC series flash chips support SOP8 and USON8 packages, suitable for portable product designs.
