Digilent PLTW S7 Reference Manual

PLTW S7 Reference Manual
Revised July 11, 2018
This manual applies to the PLTW S7 rev. A
Overview
The PLTW S7 is a small, 48-pin DIP form factor board built around a Xilinx Spartan-7 FPGA. 32 FPGA digital I/O
signals, 2 FPGA analog input signals, an external power input rail, and a ground are routed to 100-mil-spaced
through-hole pins, making the PLTW S7 well-suited for use with solderless breadboards. At just 0.7" by 3.05"
inches, it can be loaded in a standard socket and used in embedded systems. The board includes a programming
ROM, clock source, USB programming and data transfer circuit, power supplies, LEDs, and buttons.
