When choosing a flashing utility, technicians generally choose between NeoProgrammer, AsProgrammer, Flashrom, or the official CH341A Programmer software. NeoProgrammer V2.2.0.10 Official CH341A Software AsProgrammer GUI (Visual, Easy) GUI (Outdated) CLI (Command Line Only) GUI (Minimalist) 93/95 Series Support Verification Speed Fast (Optimized) Database Updates User-editable XML Discontinued Frequent (Linux-driven) OS Compatibility Windows XP to 11 Windows XP/7 Linux, macOS, Windows
: Before writing new data, click "Erase IC" to clear the chip.
Open the extracted folder, navigate to the Drivers/CH341A directory, and run SETUP.EXE . This installs the necessary drivers for the USB device. Run Application: Launch NeoProgrammer.exe . Neoprogrammer V2.2.0.10
b) Integrate into existing repo
: It is compatible with a wide range of 24-series I2C and 25-series SPI EEPROM/Flash chips from major manufacturers like Winbond, MXIC, and Micron. This installs the necessary drivers for the USB device
V2.2.0.10 includes an updated, massive database of supported chips ( series), including many newer 1.8V1.8 cap V SPI Flash chips that older software struggles to identify.
For most users, a standard black PCB CH341A with a SOP8 test clip paired with Neoprogrammer V2.2.0.10 is the most cost-effective solution. V2.2.0.10 includes an updated
: Creating a backup (dump) of current firmware before making experimental changes.
Navigate to the subfolder Drivers/CH341A/ . Run SETUP.EXE and click Install to deploy the parallel port/interface driver layer ( CH341PAR ) needed for programming operations.
Previous versions capped SPI read speeds at roughly 200-250 KB/s. V2.2.0.10 introduces a new buffering algorithm that pushes the CH341A to its theoretical limit of ~350-400 KB/s. When flashing a 16MB BIOS, this reduces wait time from 80 seconds to under 45 seconds.
