Universal EPROM programmer and UV eraser kit

The GQ PRG-109 GQ-4X V4 combines a True USB universal programmer with a dedicated UV eraser in a single package. It targets engineers, technicians and hobbyists who need to read, program and erase a wide range of EPROM, EEPROM and flash devices. The robust enclosure houses a 40-pin ZIF socket for secure chip insertion. No external power adapter is required for typical operation.

40-pin ZIF socket with True USB interface

The programmer supports devices up to 256 Mbit capacity, covering common SPI flash and parallel EPROM chips. Fast-mode SPI and JTAG support extend the range to many modern microcontrollers and programmable logic parts. Throughput is up to 20 times faster than earlier Willem-style designs, reducing programming cycles for production or repair work. Very high-density or specialised NAND devices fall outside the supported list.

Bundled UV eraser and lifetime software updates

The included UV eraser lets you blank windowed EPROMs on the bench without sending them out, saving turnaround time on legacy board repairs. GQ-USB software runs on Windows XP through Windows 11, both 32-bit and 64-bit editions, and receives free lifetime upgrades. Multi-language menus include English, French, German, Spanish, Portuguese, Czech and Chinese. Users needing macOS or Linux native support must seek alternative toolchains.

Questions about this item

Will the 40-pin ZIF socket on this GQ-4X4 programmer accept the older EPROMs I already have?

The 40-pin ZIF socket is fully automatic and eliminates jumpers, so it handles a wide range of legacy EPROMs without manual setup.

How can I confirm the UV eraser is clearing chips properly after the cycle finishes?

The eraser is paired with the programmer; after a cycle, insert the chip into the 40-pin ZIF socket and run a blank-check in the GQ-USB software to verify erasure.

Does the package include any adapters for smaller packages, or must I buy them separately?

The box contains the GQ-4X4 programmer with 40-pin ZIF socket and the UV eraser; adapters for other packages are not included and must be purchased separately.
