2.5 FPGA Dedicated Pins

The following pins are hardware-dedicated on Spartan 7 FPGA. For primary guidelines, see Xilinx documentation. Descriptions in Table 2-5 are recommendations for application-specific consideration.

Table 2-5 FPGA Dedicated Pin Descriptions
PIN I/O DESCRIPTION
NAME NUMBER
PUDC B10 I Pullup during configuration

Tie either directly (or through a 1-KΩ or less resistor) to GND. This will enable pullups on pins during configuration.
PROGRAMZ N8 I Asynchronous reset to configuration logic (active low)
INITZ N7 B (open drain) Indicates initialization of configuration memory (active low)
DONE M9 B Indicates successful completion of configuration (active high)
CFGBVS_0 N9 I Tie to ground
DXN_0 J7 N/A Temperature-sensing diode pin for FPGA. Tie to ground if not used.
DXP_0 J8 N/A Temperature-sensing diode pin for FPGA. Tie to ground if not used.
M0_0 L10 I Configuration mode select

Tie to 1.8V.
M1_0 L8 I Configuration mode select

Tie to ground.
M2_0 L9 I Configuration mode select

Tie to ground.
HSTL VREF C4, L3 REF Voltage reference for HSTL 1.8-V input
TDO(1) M6 I JTAG data output
TDI(1) M7 I JTAG data input
TCK(1) A8 O JTAG clock
TMS(1) L7 I JTAG mode select
