FPGA – LCD Interface

An 8 × 1 LCD module is provided on the ProASIC3 Evaluation board for demonstrating the board’s functionality.

provides detailed information about the LCD module.

Description

The LCD module MDLS-81809-SS-LV-G-LED-04-G can be operated in either 4-bit data mode or 8-bit data mode.
In this PA3 evaluation board, the above LCD module is being operated in 4-bit data mode to minimize the number of
FPGA lines committed to the interface. The 4-bit data lines (DB4, DB5, DB6, and DB7) and the required control
signals for this LCD module, specifically RS (Register Select), R/~W (Read/~Write), and E (Enable) lines, are driven
from BANK0 I/O lines of FPGA. These BANK0 I/O lines of FPGA are configured as LVTTL outputs for driving the
LCD.

Both V

CCI

and VMV power points of Bank0 are from a fixed 3.3 volts source, thereby enabling BANK0 to function in

LVTTL mode.

The interconnection details between the FPGA and the LCD module are listed in

Table 2-4 on page 19
