EPXA1 Development Board Hardware Reference Manual
General Usage
Guidelines
To use the development board properly, and to avoid damage to it, follow
the guidelines in this section.
Anti-Static Handling
Before handling the development board, you should take proper anti-
static precautions, otherwise it can be damaged.
Power Consumption
The level of power consumption in the EPXA1 development board
depends on what peripherals are implemented in the FPGA, typically in
relation to the following variables:
■ Number of interfaces used
■ Density and speed of the device
■ Population of the interfaces
The board’s typical operating current while running diagnostics is
approximately 250 mA.
A 20-W power supply is supplied as part of the EPXA1 development kit.
It is capable of meeting the maximum power requirement imposed by the
board if all interfaces are used within specification.
