This new generation true-USB Willem EPROM programmer (GQ-3X) is the first, fully automatic, USB port as
data transfer, high speed, most user-friendly Willem EPROM universal programmer in the market.
It uses only one USB cable to connect with PC/Laptop USB port for both data transfer and power supply.
The bulky DB25 data cable is no longer needed. The USB EPROM Programmer is ideal to use for portable
and convenient applications, such as newer laptop, car/automotive field ECU chip tuning...
It is a fully automatic EPROM programmer which eliminate all jumpers & DIP switch on the parrellel
willem programmer board. This extends the programmer life time and makes much easier & very simple to
use for end users. Manual set-up for DIP switch and jumpers is no longer needed.
It connects PC via high-speed USB link, provides the fastest possible data transfer rates for
programming/reading data from target IC's. It is capable of being up to 20 times faster than other
existing printer port willem (parrellel willems) programmers on reading & verification a high density
flash device, this significantly saves your time and increases work efficiency as well as facilitate
small scale production.
GQ-3X Key Features Summary
Universal Programer supports over thousand chips & growing
USB port data transmission with PC/Laptop no longer need DB25 data cable which is required by
Significantly increase the speed up to 20 times faster than all LPT Willems ((PCB5.x,4.5x, 4.x..)
Updates software and device algorithm regularily and free IC device updates via web
Auto programming voltage control prevent chip from damage by set wrong voltage jumper
Power suppuly can be from USB port or AC external power supply by auto detection
On-Board MCU for ensuring most stable performance
Eliminate all on-board sockets of LPT willems, all DIP chips use ZIF to protect chip lead broken
Eliminated all DIP and jumpers on board. The user no longer need to worry about the jumper settings &
DIP switch setting, fully automatic
Fixed all hardware design issues in Enhanced Willem. Improved the voltage management from GQ-2X model.
Binary data editing,device search feature,batch run and short cut key operations
Supports the chips that LPT Willem are not capable of supporting, like 24RF08,28F102,87C257 and more
Support TSOP48,PSOP44,16bit EPROM chips that 40 pin TOP,EasyPro are not capable of supporting
