KC705 Evaluation Board 51
UG810 (v1.8) March 20, 2018 www.xilinx.com
Chapter 1: KC705 Evaluation Board Features
The character display runs at 5.0V and is connected to the FPGA's 1.5V HP bank 33 through
a Texas Instruments TXS0108E 8-bit bidirectional voltage level translator (U10). Figure 1-21
shows the LCD interface circuit.
The KC705 board base board uses a male Samtec MTLW-107-07-G-D-265 2x7 header (J31)
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 1-22.
