 SPI Flash (即SPI Nor Flash)是Nor Flash的一种,NOR Flash根据数据传输的位数可以分为并行(Parallel)NOR Flash和串行(SPI)NOR Flash,SPI Nor Flash每次传输一个bit位的数据,parallel Nor Flash每次传输多个bit位的数据,SPI Nor Flash比parallel便宜,接口简单点,但速度慢。NOR Flash是一种非易失性的存储器,具有存储容量大,数据保存时间长的特点,其擦写次数多达10万次,数据更新速度比EEPROM要快很多,在断电的情况下也能保存数据,常用来保存一些重要的配置信息。
武汉新芯  武汉新芯集成电路制造有限公司于2006年成立,武汉新芯是业界领先的NOR Flash供应商,产品覆盖主消费类、工业物联网、汽车电子等各类终端市场。武   汉新芯生产的图像传感器(CIS)芯片兼备高性能和低功耗的优势,已成功打入国内主流智能手机品牌供应链。
