The GW2A/GW2AR series FPGA products utilize multiple voltage types:
- Core voltage (VCC)
- PLL voltage (VCCPLL)
- Auxiliary voltage (VCCX)
- Bank Voltage (VCCIO)
VCCX serves as an auxiliary power supply for internal chip connections, typically requiring 2.5V or 3.3V. Without proper VCCX supply, I/O, OSC and BSRAM circuits will be affected, rendering the chip non-functional.
Users must ensure operation within recommended working conditions. For power consumption analysis, the GPA tool can evaluate specific densities, encapsulation and resource utilization.
Recommended power-on time range: 0.2ms to 2ms.
Each FPGA power input pin should connect to ground through a 0.1μF ceramic capacitor. VCC core voltage input requires specific noise processing.
JTAG download enables bitstream data transfer to SRAM, on-chip flash or off-chip flash.
