# SPI NAND Flash Driver This driver is designed to support SPI NAND Flash with ESP chipsets. This component incorporates the [dhara library](https://github.com/dlbeer/dhara), licenced under the [LICENCE](https://github.com/dlbeer/dhara/blob/master/LICENSE) ## About SPI NAND Flash SPI NAND Flash combines the benefits of NAND Flash technology with the simplicity of the SPI interface, providing an efficient and cost-effective solution for non-volatile data storage in diverse applications. Its versatility, reliability, and affordability make it a popular choice for many embedded systems and electronic devices. ### Key Features: * Non-Volatile Storage: SPI NAND Flash provides non-volatile storage, retaining data even when power is removed. This characteristic makes it ideal for storing critical system information and application data. * SPI Interface: The SPI protocol allows for straightforward communication between the microcontroller and the NAND Flash. This simplicity in interface design facilitates easy integration into embedded systems. * Cost-Effective: SPI NAND Flash offers a cost-effective storage solution, making it attractive for applications with budget constraints. Its competitive pricing makes it a viable option for a wide range of projects. * High Density: NAND Flash technology inherently supports high-density storage, enabling the storage of large amounts of data in a compact form factor. This is advantageous for applications requiring extensive data storage in constrained spaces. * Fast Read/Write Operations: The SPI interface enables reasonably fast read and write operations, making it suitable for applications where data access speed is crucial. ## Supported SPI NAND Flash chips At present, `spi_nand_flash` component is compatible with the chips produced by the following manufacturers and and their respective model numbers: * Winbond - W25N01GVxxxG/T/R, W25N512GVxIG/IT, W25N512GWxxR/T, W25N01JWxxxG/T, W25N01JWxxxG/T * Gigadevice - GD5F1GQ5UExxG, GD5F1GQ5RExxG, GD5F2GQ5UExxG, GD5F2GQ5RExxG, GD5F4GQ6UExxG, GD5F4GQ6RExxG, GD5F4GQ6UExxG, GD5F4GQ6RExxG * Alliance - AS5F31G04SND-08LIN, AS5F32G04SND-08LIN, AS5F12G04SND-10LIN, AS5F34G04SND-08LIN, AS5F14G04SND-10LIN, AS5F38G04SND-08LIN, AS5F18G04SND-10LIN
