Overview
The Digilent PmodUSB2 Module Board (the
USB2) is used to create a USB 2.0 connection
on any Digilent system board.
The USB2 is based on the Cypress
CY7C68013 USB controller and can be used
to configure system boards or exchange data
with a PC.
Digilent firmware in the Cypress USB controller
works with Digilent’s PC-based Adept software
to coordinate JTAG programming and user
data transfers. The data port uses a protocol
similar to the 14-signal “Enhanced Parallel
Port” (EPP) protocol.
The USB2 is compatible with all newer Digilent
system boards including the Spartan-3,
Pegasus, D2SB™, and D2FT™ boards. It can
also be used with the older D2 and D2E
boards for user data transfers, but not for
programming. For more information, see the
reference manuals at
www.digilentinc.com
.
Features include:
• USB 2.0 connector
• status indicator LED
• Cypress CY7C68013 USB controller
• small form factor (3.00” x 2.20”).
