Support systems with mixed supply rails by interfacing two independent voltage domains in a single configurable device.
Add level translation capability as part of the configurable design, supporting translation in either direction depending on design needs.
Consolidate voltage‑bridging and supporting logic into one device to simplify component count and routing.
Configure I/O behavior (input/output/dynamic control) per design requirements while operating across domains.
Use GreenPAK tools and development hardware to implement and adjust designs quickly as requirements evolve.
Combine level translation with programmable logic, timing, and mixed‑signal functions in the same device.
Dual Supply GreenPAK devices partition I/O across two supply domains—primary supply (VDD) and secondary supply (VDD2)—so signals can be received and driven in each domain while the internal configurable resources bridge behavior between them. This enables mixed‑voltage interfacing without forcing the entire system onto a single logic level.
Dual Supply GreenPAK supports level translation from the higher voltage domain to the lower domain or vice‑versa, depending on how the design configures signal routing and I/O roles. This flexibility supports mixed‑voltage subsystems where directionality may vary across signals or operating states.
At the simplest level, Dual Supply GreenPAK can be configured for direct signal transmission across domains, as the page illustrates with pins associated to VDD and VDD2. More advanced designs can route and condition signals using internal logic/timing resources before crossing domains, keeping domain bridging aligned to system behavior.
Beyond direct translation, designs can enable signals to pass selectively in one direction under control of another input signal—supporting use cases like shared lines, controlled directionality, or conditional interfacing between subsystems.
