Appendix A. Pin Connections

HSMC.FPGA for the

Cyclone III Starter Board

Introduction

The section describes the HSMC pin connections for Cyclone III Starter

Board. See Tables A–2

Special caution when building applications with the LCD Multimedia

HSMC and the Cyclone III FPGA Starter Board:

c The LCD Multimedia HSMC uses the differential pair

HSMC_CLKIN pins as single-ended I/O. On the Cyclone III

Starter Board, the n and p signals for these pins are terminated

with 100 Ohm resistors (R3 and R4).

These signals correspond to single-ended I/O on the LCD

Multimedia HSMC. R3 connects HC_RX_CLK and

HC_TD_27MHZ and R4 connects HC_ADC_PENIRQ_n and

HC_TX_CLK. To avoid unwanted noise on signals, users are

advised to turn off the peripherals as shown in the Table A–1

below.
