Feature Descriptions
The character display runs at 5.0V and is connected to the FPGA 3.3V HP bank 14 through
a TI TXS0108E 8-bit bidirectional voltage level translator (U45).
Figure 1-27 shows the LCD
interface circuit.
The AC701 board base board uses a male Samtec MTLW-107-07-G-D-265 2x7 header (J23)
with 0.025 inch square posts on 0.100 inch centers for connecting to a Samtec
SLW-107-01-L-D female socket on the LCD display panel assembly. The LCD header
shown in
Figure 1-28.
