Chapter 1: VC707 Evaluation Board Features
The VC707 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 1-21. When the LCD is not installed, the J31 header pins listed in
Table 1-23 are available for use as GPIO.
Table 1-23 lists the connections between the FPGA and the LCD header.

C Bus
[Figure 1-2, callout 20]
The VC707 board implements a single I
2
C port on the FPGA (IIC_SDA_MAIN,
IIC_SDA_SCL), which is routed through a 1-to-8 channel I
2
C bus switch (U52). The bus
switch can operate at speeds up to 400 kHz.
The bus switch I
2
C address is 0x74 (0b01110100) and must be addressed and configured
to select the desired downstream device.
