No, the G540 provides 5V and 3.3V power logic. Programming 1.8V chips requires a physical 1.8V adapter accessory to prevent damaging the low-voltage chip.

Finding the official software for the programmer can be challenging as the original manufacturer's website is often offline or difficult to access. Since the device is considered "legacy" or "orphaned" by many in the community, you can find the software and drivers via the following community-maintained and archival links: Software & Driver Download Links

Clean the pins of the chip being programmed. If you are using a SOP8 to DIP8 adapter, ensure the adapter is seated firmly in the ZIF socket with the handle locked down completely.

If you have lost your original CD, the hosts ISO images of the original software discs provided with the hardware.

The official source is or authorized resellers. Since the product is discontinued in some regions, here are safe approaches:

: While frequently down, the official download page was historically located at stg51.com.

USB bus-powered (No external adapter required)

Because the official software development stopped around version 5.57, the native chip list cannot be updated online. For unsupported modern 3.3V SPI chips, you may need to use a third-party software alternative or step up to a newer hardware programmer like the T48 or TL866II Plus. Does the G540 support 1.8V chips?
