NeoProgrammer is a fork (an updated version) of the famous AsProgrammer software. Version 2.1.0.19 represents a mature, stable release that supports hundreds of additional chips compared to the original CH341A programmer software.
Unlike the cheap Chinese software that comes on a mini-CD (or a broken download link), NeoProgrammer offers:
The CH341A is a diamond in the rough, but it needs the right software to shine. The stock tools are essentially proof-of-concept code. Neoprogrammer 21019 is the polish, the power, and the reliability that the CH341A always deserved.
Whether you are:
...the combination of Neoprogrammer 21019 and the CH341A is your ultimate weapon. Download it, master the workflow, and never fear a corrupted flash again.
Final Pro Tip: After you’ve successfully flashed your chip, always keep a folder on your desktop named CH341A_Neoprogrammer with the drivers, the .exe, and a copy of your stock BIOS backup. The next time you brick a device (and there will be a next time), you’ll thank yourself.

NeoProgrammer 2.1.0.19 is a specialized, open-source software suite designed to interface with the ubiquitous CH341A USB programmer. It is a modern successor to the older ASProgrammer project, offering a more stable and feature-rich environment for flashing BIOS chips, EEPROMs, and SPI Flash memory. Key Features of NeoProgrammer 2.1.0.19
This specific version is highly regarded for its expanded chip database and user-friendly interface.
Integrated HEX Editor: Allows users to view and modify binary data directly before flashing (e.g., editing MAC addresses in router firmware).
Auto-Detection: For SPI (25-series) chips, the software can automatically read the JEDEC ID/signature and identify the correct chip profile.
Broad Compatibility: Supports a vast range of 24-series (I2C) and 25-series (SPI) memory from manufacturers like Winbond, MXIC, and STMicroelectronics. neoprogrammer 21019 ch341a
Language Localization: Supports multiple languages. If the interface defaults to a foreign language, users can manually add an English translation file to a "languages" folder in the program directory. Step-by-Step Guide: Using NeoProgrammer with CH341A 1. Hardware Preparation and Drivers
Before launching the software, ensure your CH341A hardware is correctly configured:
Install Drivers: Download and run SETUP.EXE from the official WCH driver package to ensure Windows recognizes the USB device.
Voltage Checks: Many CH341A "black edition" programmers output 5V on data lines. If you are working with 1.8V chips, such as those found in modern laptops, you must use a 1.8V level shifter/adapter to avoid damaging the IC.
Chip Orientation: Align "Pin 1" (marked by a dot on the chip) with the notch on the programmer. For 25-series SPI chips, use the slot furthest from the USB port. 2. Reading and Backing Up
Always backup the original chip content before performing any write operations. Connect the programmer to your PC.
Click Detect. If properly connected, a window will pop up with the identified chip.
Click Read to load the chip’s current firmware into the buffer.
Once the progress bar completes, click Save to create a backup file (.bin or .hex). It is recommended to read the chip twice and compare the files to ensure data integrity. 3. Erasing and Programming Click Open to select your new firmware file.
Use the Erase function to clear the existing data on the chip.
Click Program (or the "Write" icon). In NeoProgrammer, you can often use a "Combined" action that automates Erase -> Write -> Verify in one sequence. NeoProgrammer is a fork (an updated version) of
Verify: The software will compare the data written to the chip against the source file. A "Verification Successful" message is critical for confirming the flash worked. Supported Chips & Hardware Variations
While NeoProgrammer is a software tool, its utility depends on the hardware version of your programmer. Standard CH341A Enhanced CH341B Max Speed Stability Good (Requires manual drivers) Excellent (Native Windows 10/11 support) Voltage Support Primarily 3.3V/5V Improved high-speed signal integrity Compatible Families: 24 Series: I2C EEPROMs (AT24C02, etc.) 25 Series: SPI Flash (W25Q64, MX25L128, etc.)
93/95 Series: Supported via specific adapters in later NeoProgrammer versions. Common Troubleshooting
"Chip ID: FFFFFF": This usually indicates a poor connection between the SOIC8 clip and the chip. Ensure the pins are clean and the clip is seated firmly.
Device Not Found: Check Device Manager. If it appears as an "Unknown Device," re-install the WCH CH341 Serial/Parallel drivers.
To create a post or guide for using NeoProgrammer (v2.1.0.19 or later) with the CH341A USB programmer, you can follow this structured format. This software is often preferred over the standard CH341A software due to its better chip detection and reliability. Essential Preparation
Hardware Setup: Ensure your CH341A is connected correctly. Use the 25 SPI slot for BIOS chips and the 24 I2C slot for other EEPROMs.
Drivers: Install the correct CH341PAR (parallel/SPI) drivers to ensure Windows recognizes the programmer.
Safety: If programming in-circuit (on the motherboard), remove the CMOS battery and disconnect all power sources to avoid damaging the chip or programmer. Step-by-Step Programming Guide
NeoProgrammer version 2.2.0.10 is an updated, community-maintained software tool for the CH341A USB programmer, supporting 24-series I2C and 25-series SPI Flash memory chips for bios and firmware repairs. It supports auto-detection of ICs, reading, writing, and verification of binary files, and is frequently used to upgrade or restore firmware on various electronic devices.
