Version 21013 expects the original CH341A driver.
The software is primarily maintained and shared through community platforms:
: Open AsProgrammer.exe . Select your hardware type and the specific IC model.
A: Because the software directly accesses hardware (IO ports). This is a privilege that malware also abuses. Whitelist the folder.
: Includes an "Unprotect" function to clear write-protection bits, though it is designed not to touch the second status register to avoid permanent chip damage. How to Use and Download asprogrammer 21013 2021 download
: Memory detection, reading, and writing algorithms were entirely overhauled to maximize safety and speed.
Since ASProgrammer is an open-source project, it is widely mirrored across the internet. However, the safest way to download it is from the official developer’s repository.
This specific version is favored for its stability and broad hardware support. Notable features include:
Acquire the utility from trusted developer hubs such as the official nofeletru UsbAsp-flash GitHub repository or vetted community tech boards like 4PDA . Version 21013 expects the original CH341A driver

At its core, AsProgrammer is a free, open-source graphical utility that can read, erase, and write to serial memory chips. Initially developed as a tool for the UsbAsp programmer, it has been around since late 2011 and is actively maintained. The software is released under the and, in its original form, is a portable application that does not require installation. Its primary purpose is to interface with common, inexpensive hardware programmers like the CH341A , allowing enthusiasts and professionals to read and write data to numerous flash memory chips.
Despite its age, version 2.1.0.13 offers a rich set of features that make it a powerful tool for anyone working with serial memory:
Double-click the AsProgrammer.exe file in the extracted folder. The application window will open. A: Because the software directly accesses hardware (IO
If you are using the older CH341A Programmer software (v1.30 or v1.34), you might encounter issues like: "Chip not found" or "ID 000000" errors. Verification errors (failed to write).
: Restore original firmware to routers bricked during a bad update or custom firmware installation.
: Utilized in automotive dashboard clusters, odometer chips, and specialized network cards. Step-by-Step Installation and Setup
By understanding the strengths and limitations of AsProgrammer 2.1.0.13, you can decide if it is the right tool for your next low-level hardware project.
