SPI Flash (ie SPI Nor Flash) is a kind of Nor Flash. NOR Flash can be divided into parallel (Parallel) NOR Flash and serial (SPI) NOR Flash according to the number of bits of data transmission. SPI Nor Flash transmits one bit at a time Parallel Nor Flash transfers multiple bits of data at a time. SPI Nor Flash is cheaper than parallel. The interface is simpler, but the speed is slower. NOR Flash is a non-volatile memory with the characteristics of large storage capacity and long data retention time. The number of erasing and writing is up to 100,000 times, and the data update speed is much faster than that of EEPROM. Can save data, often used to save some important configuration information. 
Zbit Semi, Inc.can provide Flash memory with general SPI interface. The main products are ZB25LD/ZB25LQ series with 1.8V working voltage, ZB25VQ/ZB25D series with 3.0V working voltage, and ZB25WD/ZB25WQ series with 1.8/3.3V wide working voltage. The available capacity ranges from 1Mbit to 256Mbit. The quiescent current of Hengshuo Semiconductor SPI NOR Flash products is as low as 1uA, the data retention time is 20 years, the number of erasing and writing can reach 100,000 times, and the operating temperature range is -40℃～105℃. The product has high reliability, low power consumption, and advanced safety features
