Power supply

1. Overview

The voltage types of the GW2A/GW2AR series FPGA products include

Core voltage (VCC),PLL voltage (VCCPLL), auxiliary voltage (VCCX), and Bank

Voltage (VCCIO).

VCCX is an auxiliary power supply used to connect the internal parts of the chip and is usually powered by a 2.5V or 3.3V power supply. If VCCX does not exist,I/O,OSC and BSRAM circuits will be affected and the chip will not function properly.

2. Power index

Users should ensure that GOWINSEMI products are always available

Recommended working conditions and scope. The data exceeds the work.

The conditions and scope are for reference only. GOWINSEMI does not guarantee that all equipment is in compliance with standards

Operate as expected beyond the working conditions and scope.

For specific densities, encapsulation and resource utilization, the GPA tool can

Used for evaluating and analyzing power consumption.

4. Power-on time

Reference range for power-on time :0.2 milliseconds to 2 milliseconds.

Attention!

Youdaoplaceholder7 If the power-on time exceeds 2 milliseconds, you need to make sure that in

In the sequential power-on process, it starts with VCC, followed by VCCX/VCCIO.

If the power-on time is less than 0.2 milliseconds, it is recommended to increase it

Capacitors are used to extend the power-on time.

5. Power filter

Each FPGA power input pin passes through a 0.1uF

The ceramic capacitor is connected to ground.

The input terminal of the VCC core voltage should mainly be carried out

Noise processing. For specific reference, please refer to Figure 1:
