CoolRunner-II™ Starter Board Reference Manual
Revised April 8, 2016
This manual applies to the CoolRunner-II rev. F
Overview
The CoolRunner-II Starter Board is a complete USB-powered circuit development platform for Xilinx's CoolRunner-
II CPLD. The board includes highly-efficient power supplies, a programmable oscillator, several I/O devices, and a
USB2 port for board power and CPLD programming. The board also includes five expansion connectors that make
64 CPLD signals available to external circuits.

  • Page 2: Power Supplies

    CPLD's behavior. Power Supplies The CoolRunner-II board can be powered from its integral USB port or from an external supply attached at connector JP3. Jumper JP2 selects whether the board uses USB power or external power. External power, from any source, is routed through a Maxim LT3028 regulator to produce the two voltage supplies (3.3V I/O and 1.8V core)
  • Page 3 IC3. User I/O The CoolRunner-II board provides two pushbuttons and two slide switches for inputs, and four red LEDs and a four- digit LED display for outputs. The active-low pushbuttons and slide switches include series resistance for short-circuit protection. The LEDs are active low, and the seven-segment display uses decoupled-transistor active-high common anode signals and active-low cathodes.

  • Page 4: Expansion Connectors

    GND connections and eight unique CPLD signals. Each port can accommodate a single 12-pin Pmod or two 6-pin Pmods. Digilent makes several 6-pin Pmods that can attach to these ports, including speaker boards, H-bridge boards, sensor boards, etc. See for more information.
