TL866II Plus Universal Programmer | USB IC Programmer

Software Installation: Download and install the latest version of the dedicated software (e.g., Xgpro) from the manufacturer’s or distributor’s website. This is crucial for accessing the full chip database.
Hardware Connection: Connect the programmer to your computer’s USB port using the provided cable. The device is powered entirely via USB.
Selecting the Chip:
- Open the software.
- Use the “Search” or “Select” function to find your target IC. You can search by chip manufacturer, type, or part number (e.g., “ATmega328P”, “W25Q128”).
Placing the Chip:
- Lift the lever of the 40-pin ZIF socket.
- Carefully orient the IC according to the pin-1 diagram printed on the socket.
- Place the chip into the socket and lock it down by closing the lever.
Basic Operations:
- Read: Reads the content of the chip and saves it to a file on your computer (.bin for data, .hex for MCUs).
- Program: Load a firmware file (.bin, .hex) from your computer and burn it into the chip. The software will automatically erase, program, and verify the chip.
- Verify: Compares the data on the chip against a file on your computer to check for errors.
- Erase: Clears the content of the chip.
Adapter Usage (for non-DIP chips):
- For SMD chips (SOIC, TSSOP, etc.), you will need separate SOIC8, SOIC16, or other adapters.
- The adapter plugs into the ZIF socket, and the SMD chip is placed on the adapter’s footprint, often secured with a clip.

High-Count Support: Programs over 15,000+ different IC chips.
Wide Protocol Range: Supports SPI Flash, NAND Flash, EEPROM, MCUs (like PIC & AVR), and many other logic devices.
USB Connectivity: Connects to a computer via USB for easy control and software updates.
Fast Programming: Features high-speed programming and verification for efficient work.
Advanced Features: Includes IC testing, eeprom.bin file generation, and a built-in logic analyzer (limited).
40-Pin ZIF Socket: A Zero Insertion Force socket protects IC pins and makes insertion/removal easy.

Description
Review

The TL866II Plus is a professional-grade, USB-powered universal programmer designed for engineers, technicians, and serious electronics hobbyists. It stands out for its incredible support of over 15,000 integrated circuits, making it one of the most versatile tools on the market for device programming and testing. Its core functionality covers a massive range of memory chips (including SPI Flash, parallel Flash, NAND Flash, and EEPROMs) and a wide array of microcontrollers (MCUs) from popular families like Microchip PIC and Atmel AVR.

Beyond simple programming, the TL866II Plus is packed with advanced features. It can test logic ICs (like 74-series chips) for functionality, read and save data to standard binary files (crucial for firmware backups), and even generate files for automotive EEPROMs. It includes a simple logic analyzer function for signal debugging. The high-quality 40-pin ZIF (Zero Insertion Force) socket ensures that even delicate chips can be inserted and removed hundreds of times without risk of bending or breaking pins. Controlled through intuitive Windows software, it offers a reliable, fast, and comprehensive solution for nearly any programming task in a lab, repair shop, or production environment.

Unmatched Versatility: A single tool for programming memory, microcontrollers, and testing logic, reducing the need for multiple dedicated programmers.
Time Efficiency: High-speed programming algorithms and a user-friendly software interface significantly speed up development and production workflows.
Reliability & Safety: The ZIF socket and robust software with verification steps prevent damage to valuable chips and ensure data integrity.
Future-Proof: Regular software updates from the manufacturer add support for new chips, extending the tool’s useful life.
Essential for Repair: Indispensable for repairing modern electronics (e.g., motherboards, game consoles) that require firmware flashes on SPI or NAND chips.
Cost-Effective Solution: Replaces several more expensive, dedicated programmers with one capable unit.
