Low-Cost Programming Stick (LCPS)
Interface
The development board can be programmed by the low-cost programming stick (LCPS) or via a 10-pin FP3 header
(
Figure 4-24 ). Regardless of the programming dongle used, IGLOO PLUS is programmed the same way as IGLOO
nano, ProASIC3, and Fusion FPGA devices.The LCPS is a special version for the FlashPro3 programming circuitry
that is compatible with FlashPro3 and the generic FlashPro programming software. The LCPS, like the IGLOO PLUS
board, is RoHS-compliant and is completely lead (Pb) free. To use the LCPS with the FlashPro software, all you need
to do is to select the FlashPro3 from the list of programmer types. The LCPS behaves exactly as if it were a regular
encased FlashPro3 programmer. The 12-pin female connector socket is designed to interface to the 12-pin right-angle
male header on the IGLOO PLUS kit. One of the pins is a special VJTAGENB signal that goes high when
programming is taking place and returns to a low level when programming has completed. This signal is connected to
the FET on the 1.5 V regulator circuit. The IGLOO PLUS board uses this signal to effect a change in the value of V
CC
from 1.2 V to 1.5 V, which is required for programming all IGLOO PLUS devices.
You do not need to have the LCPS connected to the IGLOO PLUS board to operate it, after the FPGA has been
programmed. The LCPS must be connected to the Actel IGLOO PLUS board only when programming the
AGLP125-CSG289.

Note: The LCPS supplied with this kit is intended for use with the IGLOO PLUS Starter Kit. An LCPS supplied for
other kits, although electrically and functionally equivalent, may not connect seamlessly with the IGLOO PLUS
Starter Kit board.
