Included on the starter kit board is a USB-to-UART interface with ESD protection. This interface includes an
integrated USB-to-UART bridge controller to provide a standard UART connection with the IGLOO PLUS FPGA.
Any standard UART controller can be implemented in the IGLOO PLUS FPGA to allow access with this interface. In
addition, Actel IP catalog includes various UART controllers, specifically CoreUART, which can be instantiated in the
FPGA design with an embedded processor. CoreUART controller supports both asynchronous and synchronous modes
with configurable parameters for various applications.
One application of the USB-to-UART interface is to allow for Hyper-terminal on a PC to communicate with the
IGLOO PLUS FPGA. HyperTerminal is a serial communications application program that can be installed in the
Windows® operating system. A basic HyperTerminal program is usually distributed with Windows. With an USB
driver properly installed, and correct COM port and communication settings selected, you can use the HyperTerminal
program to communicate with a design running in the IGLOO PLUS FPGA device.
Information on the USB-to-UART bridge datasheet and device drivers are available at the IGLOO PLUS Starter Kit
website page: http://www.actel.com/products/hardware/devkits_boards/iglooplus_starter.aspx.
