Understanding eMMC Chips eMMC chips are a type of embedded multimedia card (Embedded MultiMediaCard) that integrates flash memory and a controller, primarily used in mobile devices such as smartphones and tablets for storing operating systems, applications, data, and images. Whether an eMMC chip supports a specific function depends on the specifications and design of the … Read more
Among the various application scenarios for storage devices, the automotive sector is recognized as the next blue ocean market with high growth potential. However, in the past decade, global automobile sales have stabilized at around 80 to 90 million units per year. Therefore, the industry is not only focused on the incremental market brought about … Read more
As the storage field has developed, there are now many different types of storage products. Below, we will introduce several common storage types and their applications: 1. NAND NAND Flash memory is a type of Flash memory, which belongs to non-volatile memory. It uses a nonlinear macrocell architecture to provide a cost-effective solution for solid-state … Read more
RT809H Programmer Tutorial: EMMC Offline Writing Method Apply a bit of soldering flux on one side of the EMMC, use a hot air gun to heat evenly, and remove the EMMC chip. Let the removed EMMC chip cool aside, and observe the chip pins for any solder balls. If necessary, add solder or solder balls. … Read more
In high-speed circuit boards, eMMC is one of the most common and critical components, so properly routing eMMC is essential for the stable operation of the system! This article only focuses on PCB routing and does not involve schematic design! 1: Layout (1) Place the eMMC close to the main controller, ideally within 2000 mil. … Read more
EMMC Socket Usage: Enter “EMMC” under “Input Chip Marking” to see the following three options: EMMC_AUTO: Speed 8BIT (default), automatically recognized when EMMC. EMMC_AUTO_4BIT: 4BIT, recommended for most chips for stability. EMMC_AUTO_1BIT: 1BIT, can be selected when the above two cannot read; slower speed but may recover data in the chip. Additionally, the chip model … Read more
Today, I am repairing a backlogged board sent by a Taobao user, the Changhong ZLS47HIS-V1 motherboard, some small capacitors are missing. The main chip is MSD6A818, powered by 12V+24V, with a Nor Flash+EMMC combination. The symptom is that the power light is on but it won’t boot. Connecting to the programmer, the printed information is … 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
