Feature Descriptions
The ZC706 evaluation board supports both the internal XC7Z045 AP SoC sensor
measurements and the external measurement capabilities of the XADC. Internal
measurements of the die temperature, VCCINT, VCCAUX, and VCCBRAM are available.
Jumper J52 can be used to select either an external voltage reference (VREF) or on-chip
voltage reference for the analog-to-digital converter.
For external measurements an XADC header (J63) is provided. This header can be used to
provide analog inputs to the XC7Z045 AP SoC's dedicated VP/VN channel, and to the
VAUXP[0]/VAUXN[0], VAUXP[8]/VAUXN[8] auxiliary analog input channels. Simultaneous
sampling of Channel 0 and Channel 8 is supported.
A user-provided analog signal multiplexer card can be used to sample additional external
analog inputs using the 4 GPIO pins available on the XADC header as multiplexer address
lines. Figure 1-38 shows the XADC header connections.
Table 1-39 describes the XADC header J40 pin functions.
