# COLIBRI-250 a low cost FPGA development board

The COLIBRI-250 board is the smallest and cheapest devboard available to evaluate the [Microsemi/Actel ProASIC3 FPGA model A3P250](http://www.actel.com/products/pa3/default.aspx) (250Kgates). 

The Microsemi/Actel ProASIC3 flash-based FPGA chip offers a breakthrough in power, price, performance, density, and features for today's most
demanding high-volume applications" ([Microsemi web site](http://www.actel.com/products/pa3series/default.aspx)).

Two completely separate address banks of 256K x 16 bits CMOS SRAM with 12ns of access time which allow fast data
collecting capabilities and four 20x2 pin strips 2.54 mm (100 mils) pitch
to have a comfortable access to the FPGA I/O lines.

The I/O lines deliver signals to/from the FPGA fabric logic with performance of more than 300 MHz for signals and standard 3.3 Volt logic levels 
with LVDS capable interfaces. <br>

A JTAG connector fully compatible with the [Microsemi
Flash Pro4](http://www.actel.com/products/hardware/program_debug/flashpro/default.aspx#flashpro4) is available to
program the FPGA from the Libero IDE tools.

## Libero - The Integrated Design Environment (IDE) for FPGA programming

To design your hardware on the FPGA a renewable **1 year free license** of **Libero** is available from the [Microsemi web site](http://www.actel.com/products/software/libero/).

With Libero it is possible to edit, synthesize and simulate your FPGA application starting from VHDL/Verilog code obtaining an object file that can be transferred in the FPGA Flash memory through the Actel JTAG programmer available with the COLIBRI Starter Kit.
