MachXO3D Breakout Board User Guide 2. Features The MachXO3D Breakout Kit includes: MachXO3D Breakout Board – The Board is a 3” × 3” form factor that features the following onboard components and circuits: MachXO3D FPGA – Flash-based LCMXO3D-9400HC-5BG256C ...
Communication between the Board and a PC through the USB connection cable requires installation of the FTDI Chip USB hardware drivers. Loading these drivers enables the computer to recognize and program the Board. Drivers can be loaded as part of the installation of Lattice Diamond design software or Diamond Programmer, or as a stand-alone package.
This section describes the features of the MachXO3D Breakout Board in detail. 7.1. Overview The MachXO3D Breakout Board is a complete development platform for the MachXO3D FPGA. The Board includes a prototyping area, a USB program/power port, an LED array, switches, and header landings with electrical connections to most of the FPGA programmable I/O, power, and configuration pins.
7.3.2. Applying External Power The MachXO3D Breakout Board is powered by the circuit of Schematic showed on Sheet 3 of 8 based on the 5 V USB power source. You may disconnect this power source by removing the 0 Ω resistors: R35 (VCC_1.2 V) and R42 (VCC_3.3 V).
FPGA image. Resistor R23 should be re-installed if an external clock source is desired. 8.3. Determine the Source of a Pre-programmed Device If the MachXO3D Breakout Board has been reprogrammed, the original demo design can be restored. To restore the Board to the factory default, see the Download Demo Designs section for details on downloading and reprogramming the device.
