POWR1014A Breakout Board
Lattice Semiconductor
Evaluation Kit User’s Guide
Power Supply
3.3V supply rail is converted from the USB 5V interface by a linear regulator U1 when the board is connected to a
host PC.
Test Points
The ability to program the POWR1014A without enabling the device I/Os can be accomplished by powering the
VCCPROG only. After programming, VCCPROG should be left open and VCCA and VCCD should be powered for
normal operation. TP1 provides access to VCCPROG. See
Appendix A. Schematics
for more details:
• TP1, VCCPROG
USB Programming and Debug Interface
The USB mini-B socket of the POWR1014A Breakout Board serves as the programming and debug interface.
JTAG Programming
For JTAG programming a preprogrammed USB PHY peripheral controller is provided on the board to serve as the
programming interface to the POWR1014A.
Programming requires ispVM System software.
Mechanical Specifications
Dimensions: 3 in. [L] x 3 in. [W] x 1/2 in. [H]
Environmental Requirements
The POWR1014A Breakout Board must be stored between -40° C and 100° C. The recommended operating tem-
perature is between 0° C and 90° C.
The board can be damaged without proper anti-static handling.

Troubleshooting
Use the tips in this section to diagnose problems with the POWR1014A Breakout Board.
LEDs Do Not Flash
If power is applied (LED D9 illuminated) but LEDs D1 through D8 do not flash according to the preprogrammed
counter demonstration then it is likely the board has been reprogrammed with a new design. Follow the directions
in the
Demonstration Design
section to restore the factory default.
USB Cable Not Detected
If ispVM System cannot detect the USB2 cable type programming interface to the board, the incorrect USB driver
may have been installed. This usually occurs if you attach the board to your PC prior to installing the USB driver or
ispVM System software.
