1 Introduction
1.1 Product Overview
The FPGA35S6 series of FPGA boards are designed to provide a platform to create any digital I/O that is required for
your application. It interfaces with the PCIe bus and features a Xilinx Spartan 6 FPGA with a 27 MHz oscillator and
1Gb of DDR2 SDRAM. The FPGA35S6046 and FPGA35S6101 provide 32 RS-232/422/485 I/O, 24 5V tolerant I/O
and 40 3.3V tolerant high speed I/O.
