[Figure 1-2, callout 33]
7 series FPGAs provide an analog-to-digital converter (XADC) block. The XADC block
includes a dual 12-bit, 1 MSPS analog-to-digital converter (ADC) and on-chip sensors.
See 7 Series FPGAs XADC Dual 12-Bit 1MSPS Analog-to-Digital Converter User Guide
(UG480) [Ref 25] for details on the capabilities of the analog front end. Figure 1-37 shows
the KC705 board XADC support features.
The KC705 board supports both the internal FPGA sensor measurements and the external
measurement capabilities of the XADC. Internal measurements of the die temperature,
VCCINT, VCCAUX, and VCCBRAM are available. The KC705 board VCCINT and VCCBRAM are
provided by a common 1.0 V supply.
