CH341A FULL MODE PROGRAMMER 1.6

CH341A FULL MODE PROGRAMMER is a Windows utility from r.a.m Factory STORE that turns CH341A-based USB programmers into reliable tools for reading, writing, erasing, and verifying common serial memory devices. Built for BIOS recovery, embedded development, and electronics repair, it combines an expanded device library with clear, step-by-step controls.

Key features

• Broad device support: 24-series (24Cxx I2C EEPROM) and 25-series (25/25Qxx SPI NOR Flash), with automatic JEDEC ID detection where available.
• Full operations: Read, Write, Erase, Verify, Blank Check, and Status Register read/modify (including write-protect bits).
• Chip database with search and per-device presets (page size, timing, and protocol settings).
• Range programming for partial read/write and easy backup/restore.
• Built-in hex viewer/editor, checksum, and file compare tools.
• Safety-first workflow: automatic backups before writing, post-write verification, and activity logs.
• Hardware guidance: wiring checks, connection tests, and prompts for clip/sockets; supports popular CH341A boards (black/green/gold editions) and SOIC clips.
• 1.8 V device support when used with an external 1.8 V adapter.

Compatibility and requirements

• Windows 7/8/10/11 (64-bit recommended).
• CH341 driver required (WCH). Administrator privileges may be needed for installation and device access.
• May operate under Wine on Linux, though this is not officially supported.

Best practices

• Always read and save the original contents before erasing or writing.
• Use the correct voltage; low-voltage chips require a 1.8 V adapter.
• Power down target boards and isolate the chip when programming in-circuit to prevent conflicts.
