MachXO2 FPGA
The MachXO2-7000HE-4TG144C is a 144-pin TQFP package FPGA device which provides up to 114 usable I/Os
in a 20 x 20mm package. 108 I/Os are accessible from the breakout board headers.

JTAG Interface Circuits
For power and programming an FTDI USB UART/FIFO IC converter provides a communication interface between a
PC host and the JTAG programming chain of the Breakout Board. The USB 5V supply is also used as a source for
the 3.3V supply rail. A USB mini-B socket is provided for the USB connector cable.
