: Atmel AVR ( ATmega , ATtiny ), Nuvoton ( N76E003 ), and ENE embedded controllers ( KB90xx ).

Click "Erase IC" to clear the chip, then click "Write IC" to flash the new file.

Older CH341A software read every chip twice because it didn't trust its own speed. NeoProgrammer 2.1.0.19 introduces asynchronous USB polling . Suddenly, that cheap black USB dongle reads a 32MB BIOS in 40 seconds instead of 4 minutes. It detects chip IDs that the original software claimed were "Unknown."

Here is a helpful guide to getting the best results with your hardware and software. neoprogrammer 21 019 ch341a best

| Software | Hardware Compatibility | Speed | Complexity | Verdict | |---|---|---|---|---| | | CH341A only | Very Slow | Very Low | Obsolete | | AsProgrammer | CH341A, USBasp, FTDI | Medium | Medium | Good, but Neo is better | | NeoProgrammer 21.019 | CH341A, CH347, USBasp | Fast | Medium | Best for DIY | | SiberiaProg | CH341A, LPT, J-Link | Fast | High | Feature-rich but complex | | RT809H | Proprietary | Very Fast | High (Professional) | Best, but costs >$150 |

: This indicates a physical connection error. The pins are not making contact. If using an SOP8 test clip, clean the chip legs with isopropyl alcohol to remove oxidation or residual factory flux.

软件界面带有，新手也能轻松确认芯片的正确放置方向。同时还支持 Python/Lua脚本扩展 ，高级用户可以编写自动化烧录流程，满足批量生产调试的需求。 : Atmel AVR ( ATmega , ATtiny ),

根据实测，使用NeoProgrammer读取华硕B85-PLUS的16MB BIOS芯片时，，而AsProgrammer则需要2分55秒/3分钟。新版NeoProgrammer还支持 跳过FF编程载入 功能，在烧录大量空白区块时效率提升尤为明显。

Keep a copy of on three different hard drives. One day, when your UEFI is corrupt and your dog has chewed the factory cable, you will thank the ghost of some Chinese engineer who optimized that USB polling loop just right.

NeoProgrammer is a specialized fork of the popular open-source project ASProgrammer. Version 2.1.0.19 (or its close successor 2.2.0.10) is favored for several reasons: NeoProgrammer 2

The CH341A black edition programmer operates at 5V, but most BIOS chips operate at 3.3V. Using it directly can damage the chip.

: Features an "Identify" button that scans the connected chip and automatically finds the correct manufacturer and model from its database.

这是CH341A用户最容易踩的坑。许多CH341A编程器默认输出，但绝大多数现代SPI闪存芯片仅支持 3.3V 。如果将5V直接送到3.3V芯片上， 芯片几乎瞬间烧毁 。
