ASProgrammer 21.013 is the specific updated release of the popular open-source chip programming software. It is widely used by electronics hobbyists and repair technicians for reading and writing BIOS chips and other SPI flash memory.
This version (21.013) is particularly sought after because it includes updated drivers and support for newer chip models that previous versions (like 1.x) lacked. It provides a lightweight, ad-free interface for managing EEPROM, SPI, and I2C serial memory chips.
ASProgrammer is designed primarily for CH341A-based programmer hardware (the small black or blue PCBs with a ZIF socket). However, it also supports:
| Programmer Model | Compatibility | Notes | |----------------|--------------|-------| | CH341A (Black PCB) | Perfect | Most common, needs 3.3V mod for 1.8V chips | | CH341B (upgraded) | Good | Faster, but ASProgrammer may need driver tweaks | | FTDI FT232H | Limited | Not recommended for beginners | | Raspberry Pi (SPI) | Experimental | Requires additional GPIO setup |
For 99% of users, the USB CH341A programmer (costing $5–$10 on Amazon/eBay) paired with ASProgrammer 2.1.0.13 is the ultimate low-cost BIOS programming solution.
| Feature | ASProgrammer 2.1.0.13 | NeoProgrammer | CH341A Official Software | |---------|----------------------|---------------|--------------------------| | Price | Free | Free (donation) | Free (adware) | | Modern UI | ✓ Tabbed | ✓ Ribbon | ✗ Windows 98-style | | Chip database | 500+ | 1000+ | ~200 | | Auto-detect | Yes (partial) | Yes | No | | 1.8V adapter support | Manual | Auto | No | | Portable | Yes | No | Yes | | Stability on Win10/11 | Excellent | Very Good | Poor | asprogrammer 21 013 download free
While NeoProgrammer offers a larger chip list, ASProgrammer 2.1.0.13 remains the leanest, fastest, and most reliable for routine SPI work.
AsProgrammer 2.1.0.13 is a free, open-source software utility designed to program various serial flash memory chips, including SPI, I2C, and MicroWire. It is widely used by electronics enthusiasts for flashing BIOS chips, EEPROMs, and other memory components found in hardware like motherboards and routers. Key Features and Compatibility
Hardware Support: While heavily associated with the popular CH341A programmer, it also supports Buzzpirat, Bus Pirate, CH347, UsbAsp, Arduino, and FT232H.
Protocol Support: Capable of reading and writing chips using SPI (25 series), I2C (24 series), and MicroWire protocols.
OS Support: Primarily a Windows application, though community versions like AsProgrammer dregmod or variants like IMSProg offer expanded utility for Linux users. Where to Download ASProgrammer 21
AsProgrammer is distributed freely through several community-maintained repositories.
Latest Releases: You can find the most recent official builds and source code on the UsbAsp-flash GitHub Releases page, which currently lists versions up to 2.1.2 (as of early 2025).
Community Versions: For modified versions with specific chip support, the dregmod repository provides alternative builds.
Legacy Versions: Version 2.1.0.13 specifically is often bundled in large driver/software collections found on platforms like FPGA Lover's Gitea. Important Note for Users Releases · therealdreg/asprogrammer-dregmod - GitHub
