In recent years, under the demand of the Internet of Things and consumer electronics products, especially driven by various emerging applications, NOR Flash has ushered in the opportunity of turning the valley. Not only is the price of medium and high capacity stable, but the price drop of low capacity NOR Flash has also been greatly reduced. Especially driven by the mass shipment of TWS Bluetooth headsets, NOR Flash has brought huge business opportunities.
TWS Bluetooth headset must be equipped with NOR Flash, because it has more functions. In order to store a large amount of firmware and code programs, it is necessary to expand an SPI NOR Flash. As the functions of TWS Bluetooth headsets further increase, it requires more storage capacity. Take the Android mobile phone TWS Bluetooth headset as an example, generally use 8Mb or 16Mb NOR Flash. With the increase of functions, need to use 32Mb, 64Mb, or even 128Mb, 256Mb.
The SPI NOR Flash provided by RAMSUN supports standard serial peripheral interface (SPI), high-performance dual/quad output and dual/quad I/OSPI. Supports SPI clock frequencies up to 120MHz, allowing an equivalent clock rate of 240MHz for dual I/O and 480MHz for quad I/O when using fast read dual/quad I/O instructions.
