The following table is a comparison table between GQ-4X4 and GQ-4X: GQ-4X4 is the newest model of True USB Willem Universal Programmer series from MCUmall Electronics Inc Canada. With its complete new professional design, True USB PRO 40pin willem programmer GQ-4X is the first & exclusive Willem universal programmer in the market that owns the unique features: Neat robust enclosure; 40pin ZIF socket, fully automatic; JTAG support; Fast mode SPI supportSupport Windows O/S XP 32bit 64bit, Vista 32bit,Vista 64bit; Window7/8/10/11 32bit and 64bitReal True USB interface for both data transfer and power supplyHigh speed/fastest; most-user-friendly; simplest-to-useSoftware update regularly; free lifetime software upgrade/downloadMulti-languages support capability: Chinese, Czech, English, French, German, Spanish, Portuguese The application-oriented & application-enhanced design facilitates GQ-4X4 supports thousands of most popular application devices (growing) and ideally suits the portable/convenient applications that includes: car automotive field ECU chiptuning, airbag reset, mileage, satellite devices, BIOS refreshing, motherboard BIOS in-circuit upgrade, Xbox,Wii gaming machines EPROM duplicate, Altera Xilinx JTAG, PIC/MCU development, newer laptop technology and newer desktop PC etc.It has outstanding performance which supports the devices that other similar products are not capable of supporting: such as 25LF SPI series, PSOP44, TSOP48, 25VF SPI series, Altera Xilinx CPLD JTAG, PLCC84, SST39VF3201, TE28F102, 27C1024, 27C1028, HD6475,29F800, 29LV800, 29F032... Key & Unique Features 1. Complete new professional design with own robust enclosure and 40pin ZIF socket Neat robust enclosure is designed to suit the portable and field convenient applications40 pin of the ZIF socket supports more chips without the adapterFirst and only Willem programmer with 40pin ZIF socket, other models use 32pin ZIFThe software & hardware are Designed/developed by MCUmall Electronics Inc. CanadaAssembled in Canada and post-sales support by MCUmall Electronics Inc. 2. Fully automatic & no manual set-up needed (eliminate all jumpers & DIP-switch) Fully automatic for efficient use and extends the programmer lifetimeEliminates all jumpers on board, manual set-up for jumpers is no longer needed (all non-USB Willem use jumpers: 16 jumpers on PCB5.0C, 48 jumpers on Willem 1.5)Eliminate the on-board DIP switch, manual set-up for DIP switch is no longer needed.This also makes much easier & very simple to use for end users.Plug-and-play reduces the learning curve and save your precious time.3. Fast mode SPI programming & JTAG support wider the application Useful for motherboard BIOS in-circuit upgradeAltera Xilinx CPLD JTAG support 4. True USB data transfer interface with PC/Laptop for newer laptop use as well as portable application 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 eliminated & no longer needed for data transfer between PC and programmer boardIt is True/Real USB data transmission protocol (USB-USB), Not via Fake/Pseudo-USB data communication.Fake/Pseudo USB data transfer needs the middle serial or parallel port conversion: USB-Serial-USB conversion or LPT-USB conversion, this limits the programming speed significantly.GQ-4X features the same revolutionary data interface as GQ-3X, the True USB data transmission with PC/Laptop. 5. Exponentially speed increase up to 20 times faster Connects PC via the 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 LPT willems: PCB6.xx, PCB5.0C, PCB4.5C) programmers on reading & verification a high-density flash device, this significantly saves your time and increases work efficiency as well as facilitates small scale productionAssembly language written programming algorithms run fast and reliable. Not affected by the PC speed changes and Windows O/S variations. 6. Dual power supply capability: USB port & AC/DC and automatic voltage control Vcc supported among: 3.6V, 5V, 5.5V, 6.5VOn-Board MCU for stable performance & automatic/accurate voltage controlWorks best among other programmers for EPROMs 7. The GQUSB software is especially developed for True USB willem programmers GQ-4X, GQ-4X V4, GQ-3X, GQ-2X.
