User Sip Header - Xilinx SP605 User Manual

Chapter 1: SP605 Evaluation Board

User SIP Header

The SP605 includes a 6-pin single-inline (SIP) male pin header (J55) for FPGA GPIO access.
Four pins of J55 are wired to the FPGA through 200 ohm series resistors and a level shifter,
and the remaining two J55 pins are wired to 3.3V and GND. The J55 header is described in
Figure 1-18

Notes:
1. Each GPIO_HEADER_n signal is sourced from the FPGA as
2. Each GPIO_HEADER_n net has a 200 ohm series resistor between
44
and Table 1-26.
This header is not installed on the SP605 as built.
