AsProgrammer 2.1.0.13 is a widely used, lightweight Windows utility designed for flashing SPI Flash, I2C EEPROM, and Microwire chips, specifically optimized for the popular CH341A USB programmer. Key Features of the 2021 Update
The 2.1.0.13 release (often associated with 2021 updates) remains a stable choice for technicians and hobbyists for several reasons:
Broad Device Support: It works seamlessly with the black and green CH341A programmers and supports a vast library of BIOS and EEPROM chips.
Intuitive UI: Unlike command-line tools like Flashrom, AsProgrammer provides a graphical interface with a binary viewer and a "Detect" feature to automatically identify connected chips.
Safety Features: Includes built-in functions for Unprotecting chips before erasing and Verifying data after writing to ensure a successful flash.
Alternative Options: For users seeking even more frequent updates, some developers have shifted to NeoProgrammer (based on AsProgrammer), which often features newer chip definitions. Recommended Workflow for Flashing
To avoid common errors like "memory not null," follow this standard procedure:
Preparation: Power off the device and remove the CMOS battery to prevent interference.
Connection: Attach your SOIC8 clip or 1.8V adapter to the programmer, then plug the programmer into your PC. Software Steps: Detect: Click "Detect" to identify the chip.
Unprotect: Use the "Unprotect" icon to disable software write protection. Erase & Blank Check: Wipe the chip and verify it is empty. asprogrammer 21013 download 2021 exclusive
Write & Verify: Open your BIOS file, click "Program," and wait for the verification process to complete. Downloads & Resources Dumping Firmware With the CH341a Programmer
Absolutely—with caveats.
If you are repairing legacy hardware (Intel 6th to 10th gen, AM4 boards pre-2022), the ASProgrammer 21013 download 2021 exclusive is the gold standard. It is lightweight, runs on old Windows 7 test benches, and does not require an internet connection to validate a license.
However, if you are working with modern SPI flashes (1.8V, 512MB+ capacity) or Winbond W25Q512JV, you need the 2024 NeoProgrammer due to new opcodes. For everyone else, archive this version on a USB stick. It is abandonware that works—and that is rare.
If you found a link advertising "ASProgrammer 21013 Exclusive Download," be cautious. Firmware programming tools are a common vector for malware.

AsProgrammer v2.1.0.13 is a widely recognized open-source graphical interface specifically designed for hardware programmers like the
, enabling the reading, writing, and erasing of serial memory chips (EEPROM and SPI Flash). The "2021 exclusive" designation often refers to the specific stable build released that year which included updated chip databases and support for newer 1.8V and 3.3V flash modules. Deep Dive into AsProgrammer v2.1.0.13
For electronics hobbyists, repair technicians, and BIOS modders, this software serves as the bridge between raw hardware and the computer. While the original developer, Alexander
, initially created it to replace clunky factory software, version 2.1.0.13 became a community favorite for its stability. Key Features and Hardware Support Broad Chip Compatibility
: It supports a massive library of I2C, SPI Flash (24, 25, 93, 95 series), and Microwire chips. Driver Versatility : Works seamlessly with the CH341A USB programmer in both Serial and Parallel modes. User-Friendly Hex Editor Here are a few options for a review,
: Built-in hex editing allows you to modify BIOS files or serial data directly within the application before writing it to the chip. Automatic Detection
: The "Find" feature can identify many SPI flash chips automatically by reading their JEDEC ID. Why the 2.1.0.13 Build?
The 2021 version of AsProgrammer (v2.1.0.13) was a milestone update that addressed several critical issues found in earlier versions: SREG Bit Handling
: Improved logic for status register bits, preventing "write protected" errors on certain Winbond and Macronix chips. Scripting Engine
: Enhanced support for custom scripts, allowing advanced users to add support for non-standard or obscure memory chips. UI Localization
: This build consolidated various community-led translations into a single, cleaner multilingual interface. Best Practices for Downloading and Using
To ensure a safe and successful experience, follow these guidelines: Source Verification
: Always download from reputable developer repositories like or dedicated electronics forums (e.g., ) to avoid malware-laden "cracked" versions. Driver Setup : Ensure you have the CH341PAR driver installed for AsProgrammer to recognize your hardware. Voltage Safety
: Remember that many modern BIOS chips (25 series) operate at
. Using a standard 3.3V CH341A programmer without a 1.8V adapter can permanently damage the chip. Verification Step
: Always run a "Verify" operation after writing. A successful write doesn't guarantee the data is identical unless verified against the source file. using this specific version? AsProgrammer and other Windows utilities for CH341A The "Exclusive" Factor: Finding a clean
Title: A Reliable Workhorse for CH341A Users – The ASProgrammer 21013 2021 Edition
Rating: ★★★★☆ (4/5)
The Bottom Line: If you are working with BIOS chips or SPI flash memory, the ASProgrammer 21013 release from 2021 remains one of the most stable and user-friendly tools for CH341A programmers. While newer hardware revisions exist, this specific software version strikes a perfect balance between features and simplicity.
The Good:
The "Exclusive" Factor: Finding a clean, unmodified download of the 21013 version can be difficult due to the proliferation of malware-laden mirrors. This 2021 exclusive package is a gem because it includes the necessary DLLs and drivers without the bloatware. It runs smoothly on Windows 10 and 11, which is a huge plus for legacy hardware tools.
Room for Improvement:
Verdict: If you have a CH341A programmer (black or green PCB), this download is essential for your toolkit. It is stable, safe, and does exactly what it promises. Highly recommended for technicians and hobbyists alike.
Because this version retains the CLI, you can create a .bat file:
ASProgrammer.exe /chip W25Q128 /write firmware.bin /verify /exit
This is gold for refurbishing e-waste BIOS chips.
Why does this matter? Because 2021 was the great chip shortage. You couldn't just buy a new EC chip. You reflashed. ASProgrammer 2.1.0.13 became the unofficial standard for:
