SPI NOR Flash is a type of non-volatile memory that communicates using the Serial Peripheral Interface (SPI) protocol. With its low pin count, compact packaging, and high cost-effectiveness, it has long been an ideal choice for embedded system designers. The SPI interface protocol includes Standard SPI, Dual SPI, Quad SPI, and Octal SPI, with sequentially increasing data throughput capabilities to meet higher-performance transmission demands. Over the years, GigaDevice has continuously expanded the capacity range, voltage types, product series, and packaging options of its SPI NOR Flash. To date, GigaDevice offers up to 13 capacity options, ranging from 512Kb to 2Gb, with 5 different voltage types, over 20 product series, 5 temperature specifications, and more than 20 packaging choices. These cater to various market applications by providing multiple product series with high performance, low power consumption, high reliability, and compact packaging.
