First, we need to understand eMMC, eMMC (Embedded Multi Media Card) is a standard specification for embedded storage primarily aimed at products such as mobile phones or tablets, established by the MMC Association.eMMC integrates a controller within the package, providing a standard interface and managing flash memory, allowing mobile manufacturers to focus on other aspects of product development and shorten the time to market. In simple terms, eMMC=NAND+MCU.
The structure consists of an embedded storage solution with an MMC (MultiMediaCard) interface, flash memory device, and main controller, all within a compact BGA package. The interface speed can reach up to 400MBytes per second, and eMMC offers fast and upgradeable performance. Its interface voltage can be either 1.8V or 3.3V.
Major brands include Samsung (SAMSUNG), Kingston, Toshiba (Toshiba), Hynix (Hynix), Micron (Micron), SanDisk, and others, with dozens of other brands as follows:





Let’s take a common example:
Chip model: KLM8G1GETF-B041
Package: BGA153
Size: 11.5×13
Programming files: one bootloader.bin, one Userdata.bin, plus the CSD that needs to be configured.
Step 1: Device Select input the chip model.

Step 2: Import Userdata.bin in the User Area, and import bootloader.bin in the Boot1 section.


Step 3: Fill in the CSD values as required by the customer in the Device config section and check the box.

Step 4: Select the operation steps in Edit AUTO and confirm.

Step 5: Finally, save the project file and click AUTO for batch programming.
Another example:
Chip model: S40FC008C2B1I
Similarly, input the chip model S40FC008C2B1I in Device Select and find it is not supported, so we need to contact the manufacturer to notify their R&D personnel to add it. The usual time for software upgrades is 3~5 days, which may affect production.

We are a one-stop solution provider for programming, and of course, there are other solutions. Now we introduce a different solution from the above, using our AP8000 to program eMMC. I can say that currently, the industry’s programmer for programming eMMC is the most convenient and cost-effective solution, and it does not carry the risk of unsupported chips affecting production.
Our AP8000 differs from other programmers for programming eMMC in the following ways:
First: Select Chip to choose the chip model, just like other programmers.


However, if we encounter a temporarily unsupported chip model such as S40FC008C3B1I, we can just select the chip manufacturer. If the new chip is not even listed under the manufacturer, we can choose eMMC-TGeneric (eMMC Generic) for programming. This ensures compatibility with all eMMC chips. If a specific model needs to be added, we can do so, but at least it does not affect production in the meantime.
Second: Our AP8000 supports file programming and also supports programming without files, using only a Master Card. Some of our clients bring a Master Card, which is a sample, and ask if we can program it. This is also our strength; we first analyze the Master Card, and then we can start programming based on the analysis results.

Third: The programming speed is unmatched by other programmers. For 1G, 2G, 4G, 8G, you might not feel it, but for 64G, 128G, 256G, generally, other programmers take half an hour just to load the files and another half hour to program, which is unacceptable. However, our AP8000 only takes a few minutes or even seconds because we analyze before programming and only program the areas with data, greatly reducing the programming time.

Fourth: The CSD configuration; general programmers only have Option values of 177/179/167/162, but actually, eMMC has many CSD values as shown below. We also strictly follow the chip datasheet specifications for every setting function and state, allowing developers and users to better understand these configuration functions.


Fifth: Our design is very user-friendly, considering that humans can easily make mistakes, so it is very foolproof. For example, programming steps do not require manual settings, avoiding the occurrence of errors due to incorrect sequence selection.

Sixth: Finally, we have also thoughtfully designed a labor-saving fixture for our customers, making manual programming very convenient, and for large volumes, they can directly use our automated programming machine.


Learn the basics, understand the underlying logic, and programming is actually very simple!!!
