Once you have completed the Asprogrammer 2.1.0.13 download and installation, here is a typical workflow for reading and flashing a BIOS chip.
Which of the above would you like?
AsProgrammer 2.1.0.13 is a specialized, portable software utility used for reading and writing firmware to EEPROM and SPI Flash memory chips, most commonly via the CH341A programmer. It is a popular alternative to the standard Chinese software provided with these programmers because it offers better chip compatibility and a cleaner interface. Key Features
No Installation Needed: The software is portable; you simply extract the archive and run the executable.
Broad Device Support: It supports a wide range of I2C, SPI, and Microwire chips.
Automatic Detection: Includes a "Read ID" function to automatically identify connected SPI memory chips.
Multi-Platform Support: While primarily for Windows (including older versions like XP), modified versions exist for other environments. Download & Resources
Since this is open-source community software, it is best to download it from verified repositories or developer forums:
GitHub (Official/Development): Check the releases page of the UsbAsp-flash repository for the latest stable and "fix" versions.
Google Drive Mirror: A portable version of 2.1.0.13 is often shared via Google Docs/Drive by community members.
Tech Community Support: Detailed usage guides and troubleshooting for BIOS flashing can be found on forums like Win-Raid. Quick Start Guide Connect your CH341A programmer to your PC's USB port. Open AsProgrammer.exe. Go to the Hardware menu and select CH341a. Asprogrammer 2.1.0.13 Download
Go to the IC menu and select your specific chip model, or click the Read ID (?) icon to attempt automatic detection.
Use the Read, Erase, and Write icons on the toolbar to manage your firmware.
Note: When flashing a motherboard BIOS, it is often recommended to remove the CMOS battery and ensure the system is completely disconnected from power before attaching the programmer clip.
Title: Asprogrammer 2.1.0.13 Download – Latest Version for BIOS/EEPROM Flashing
Published: April 11, 2026
Category: Firmware Tools / Programmers
If you’re into BIOS modding, repairing motherboard SPI flashes, or working with 24/25 series EEPROMs, you’ve likely heard of Asprogrammer – a lightweight, open-source alternative to commercial flashing software.
The latest stable release, version 2.1.0.13, brings several bug fixes and improved CH341A programmer support.
Asprogrammer 2.1.0.13 is not a flashy tool, but it is reliable, lightweight, and essential for anyone working with low-level BIOS chips, router flash recovery, or EEPROM data manipulation. Paired with a $5 CH341a programmer, it offers professional-grade functionality at a hobbyist price.
Tip: If you need the absolute latest chip definitions (e.g., for very new 256Mbit FLASH), consider building from the GitHub source or using a newer community fork like
Asprogrammer-plus.
Would you like a direct checksum (MD5/SHA256) for the legitimate 2.1.0.13 release file to verify your download? Once you have completed the Asprogrammer 2
If you’re looking to download AsProgrammer 2.1.0.13, you are likely working with CH341A programmers to flash EEPROM or SPI Flash chips. This specific version is a popular, lightweight alternative to the "official" CH341A software, known for its better hardware support and stability. 📥 Where to Download
AsProgrammer is open-source software. To ensure you aren't downloading malware, always use these trusted sources:
GitHub (Official Repository): Search for the nofeletru/AsProgrammer repository. This is the primary home for the project where the developer releases updates.
Forum Communities: Sites like Badcaps.net or Win-Raid often host mirrors and translated versions if you need specific scripts or English patches. 🛠 Key Features of v2.1.0.13
Expanded Chip Support: Improved database for newer SPI Flash and I2C chips.
Driver Compatibility: Works well with standard CH341 serial/parallel drivers on Windows 10 and 11.
Scripting Support: Allows for automated read/write/verify sequences.
SREG Control: Better handling of Status Register bits to unprotect chips before writing. 🚀 Quick Start Tips
Install Drivers First: Ensure your CH341A programmer is recognized by Windows. You usually need the "CH341PAR.EXE" driver for programming mode.
Select Your Chip: Don't just hit "Read." Use the Search button (the magnifying glass) to type in your chip's part number (e.g., W25Q64) to ensure the voltage and timings are correct. Title: Asprogrammer 2
Unprotecting: If you get an error while writing, check the "SREG" (Status Register). Some chips are "Hardware Protected" and need their protection bits cleared within the software first.
Verify: Always perform a Verify after writing to ensure the buffer matches the chip's content. ⚠️ A Note on Voltage
Most CH341A "black" dongles output 5V on the data lines, while many BIOS chips are 3.3V or 1.8V. If you are working with sensitive 1.8V chips (like those in newer laptops), make sure to use a 1.8V adapter to avoid frying your hardware.
If you need an older build (e.g., 2.0.0.9):

⚠️ Important: Asprogrammer is hosted on GitHub. Always download from the official source or trusted mirrors.
Because this software is lightweight, it runs on almost any Windows machine. However, for a smooth experience:
| Requirement | Minimum Specification | | :--- | :--- | | Operating System | Windows 7, 8, 10, or 11 (32-bit or 64-bit) | | Processor | 1 GHz or higher | | RAM | 512 MB | | Storage | 20 MB free space | | Additional Hardware | CH341A programmer (or USBasp) | | Driver | CH341A drivers (32/64-bit) |
Note: Asprogrammer does not work natively on macOS or Linux out of the box, but it can run via Wine with minor limitations.
When you download Asprogrammer 2.1.0.13, you gain access to a robust set of tools:
Asprogrammer is a free, open-source software utility designed for reading, writing, and erasing a wide range of serial memory chips, including EEPROMs (e.g., 24Cxx, 25Cxx) and SPI FLASH memories. Version 2.1.0.13 represents a stable and widely used release in the software's evolution.
