Source: ICisC Nanjing Integrated Circuit Industry Service Center 1. Concept: SPI: Serial Peripheral Interface The SPI flash is a flash storage device that operates through a serial interface. Flash memory is categorized into two types based on its internal storage structure: NOR flash and NAND flash. Here, SPI flash belongs to NOR flash! SPI flash … Read more
The price surge of Flash continues to ferment, and many manufacturers are choosing to use more cost-effective NOR Flash chips. NOR Flash has characteristics such as strong reliability and fast read speeds, making it a major product in the mid-to-low capacity flash memory chip market. However, the long programming time and low efficiency have always … Read more
Hello everyone, I am Pi Zi Heng, a serious techie. Today I will introduce the precautions for configuring multiple registers of serial NOR Flash in FDCB. Regarding the use of the i.MXRT boot header FDCB to set the internal registers of Flash, I have previously written two articles. Before diving into this article, I recommend … Read more

Currently, China only has a presence in the small market of NOR Flash, which is a type of flash memory chip primarily used for storing code and some data. It is widely used in PC motherboards, security monitoring products, … Read more
NOR Flash technology is one of the two main types of non-volatile flash memory on the market today.Intel first developed NOR Flash technology in 1988, which completely changed the dominance of EPROM (Erasable Programmable Read-Only Memory) and EEPROM (Electrically Erasable Programmable Read-Only Memory).In 1989, Toshiba introduced the NAND Flash structure, emphasizing lower cost per bit, … Read more
1. Introduction Previously, we sharedhttps://mp.weixin.qq.com/s/BeL6UbSg2HI9qKemZugOhw?token=1054074707&lang=zh_CN the article titled“Low-Cost Learning FPGA Based on“Mining Board”” which usesJTAG boundary scan for quick pin correspondence reverse engineering.. Not only forFPGAs, but we can also useJTAG for boundary scan testing inMCUs, provided that the corresponding chip supports this feature and the manufacturer providesBSDL files. Here, we will demonstrate using theLPC1857 … Read more
Introduction The STM32 provides flexible and diverse access implementations for external memory. This article will introduce how to utilize QSPI (QuadSPI) to implement external serial NOR Flash memory. First, the functional characteristics of the QSPI interface will be introduced, followed by hardware design and software development. Based on STM32CubeM, a reference implementation for accessing the … Read more
