The main developer, nand2mario, stopped maintaining the public build around 2020. The official repository now points to a newer fork called "ASProgrammer_new." The exclusive 21013 build was never merged upstream because of a licensing dispute regarding the included CH341DLL library. As a result, the file exists only in shadow archives—user uploads on Google Drive, Mega, and defunct forum attachments.
Warning: Because this is an "exclusive" version, many fake download sites weaponize its popularity. We have tested and verified the legitimate hash values for the 2021 exclusive.
The search for asprogrammer 21013 download 2021 exclusive ends here. This version is not just a piece of software—it is a time capsule from a pivotal moment in open-source hardware programming. With its enhanced CH341A drivers, expanded chip support, and lightweight CLI, it outperforms many paid alternatives.
Final checklist for success:
Whether you are recovering a dead BIOS, hacking a game console, or just exploring SPI flash, the 21013 exclusive will be your reliable partner. Treat it as the pro tool it is, and it will never let you down.
Extract the archive to C:\ASProgrammer\. Run ASProgrammer.exe as Administrator. You should see "v21013 (Exclusive)" in the title bar.
If you found a link advertising "ASProgrammer 21013 Exclusive Download," be cautious. Firmware programming tools are a common vector for malware. asprogrammer 21013 download 2021 exclusive
Summary: You are looking for a software tool, not a research paper. The "21013" build is a specific version of the ASProgrammer flash tool released in early 2021, widely used for BIOS flashing with CH341A devices.
AsProgrammer 2.1.0.13 is a popular open-source utility designed to read, write, and erase serial memory chips like EEPROMs and BIOS chips. It is frequently used by technicians and hobbyists for motherboard repairs, BIOS flashing, and unbricking laptops. Key Features and Compatibility
Hardware Support: Primarily used with the CH341A MiniProgrammer (the "black" or "green" USB stick). It also supports UsbAsp, AVRISP-MKII, FT232H, and Arduino-based programmers.
Protocol Support: Compatible with SPI, I2C, and MicroWire protocols.
2021 Update: While the software has been around since 2011, version 2.1.0.13 was a significant stable release circulated in 2021 that included bug fixes and expanded chip support. Where to Download
Since this is open-source software maintained by the community, it is best to download it from verified repositories to avoid malware: The search for asprogrammer 21013 download 2021 exclusive
Official Releases: The primary source for official builds is the UsbAsp-flash GitHub Releases.
Modified Versions: For advanced users, the AsProgrammer dregmod on GitHub offers additional hardware support for tools like the Bus Pirate.
Portable Versions: Many users share portable versions via Google Drive links on technical forums like 4PDA or Win-Raid. How to Use
Install Drivers: You must install the specific CH341PAR or CH341SER drivers before the software can communicate with your programmer.
Select Hardware: Open the software and select your programmer type (e.g., CH341A) from the hardware menu.
Detect Chip: Use the "Read ID" or "Detect" button to let the software automatically identify the connected memory chip. Whether you are recovering a dead BIOS, hacking
Execute Task: You can then Read the current firmware to back it up, Erase the chip, and Write a new binary (.bin) file.
Warning: Always dump (backup) the existing data from your chip before clicking "Erase" or "Write," as losing original BIOS data can make recovery difficult.

Before we focus on the exclusive 2021 build, let's establish a baseline. ASProgrammer is a free, open-source (or freemium) software used to read, write, and erase SPI (Serial Peripheral Interface) flash memory chips. It is the preferred alternative to commercial software like CH341A Programmer Software because it supports a wider range of chips, including NAND flashes, and offers better stability.
Unlike the default Chinese software that comes with cheap CH341A programmers (which often crashes or misidentifies chips), ASProgrammer provides:
ASProgrammer is distributed as freeware for diagnostic and repair purposes. The "exclusive" tag refers to community distribution, not commercial licensing. You are allowed to:
You cannot resell ASProgrammer 21013 or bundle it with malware. The original author’s copyright (2018–2021) remains in effect.
While not advertised, build 2.1.0.13 had a debug Easter egg: if you created a blank file named UNLOCK.KEY in the install directory, the software enabled 1.8V adapter emulation via software voltage tweaking. Was it dangerous? Yes. Did it save you from buying a $15 level shifter? Absolutely.
