TL866II Chip Tester and EEPROM burner

Available on Amazon and eBay


  • Support simultaneously burn with 4 Programmers each computer.
  • The minimum volume and the lowest power consumption and do not feel any heat in process.
  • Test CMOS4000 74/54 series integrated circuit. Can be located in the gate circuit error.
  • Chip auto serial number is the most complete and practical.
  • Original chip encryptionoperation on AVR microcontroller with internal RC Calibration byte.
  • The Decrypt software can not be directly run on another same type of chip.

High Speed Programming

All chips do not need external power supply, the low power consumption of its own to ensure that the USB port can provide enough power. This programmer has Built-in MCU with high-performance and high-capacity USB interface at the communication speed of 12Mbps being in line with ( For each chip) well-designed programming algorithm and USB high-speed communications. It may be one of the fastest integrated development programmers, the speed has been met the needs of small-quantity efficient production.

Programmable programming power supply

VPP and VCC programming voltages are independently program-controlled: programmable VCC is from 1.8V to 6.5V; VPP is from 1.8V to 18V. The fluctuation of power supply is minor because of the multi-stage LC filter.

Upgrade Function

This programmer is equipped with an upgrade function to allow the built-in firmware to be updated to support additional chips in the future.
