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.

A large collection of board-support IP, reference designs, and add-on peripheral module boards (Pmods) is

available at www.digilentinc.com.

The CoolRunner-II Starter Board.

 A 256-macrocell CoolRunner-II CPLD in a TQ-

144 package

 An on-board USB2 port for board power, JTAG

programming, and data transfers

 An 8MHz fixed-frequency oscillator and a

socket for a crystal oscillator

 Expansion connectors for 64 I/O signals (32 on

the Pmod ports and 32 on the parallel

connector)

 a one-wire DS28E01Q EEPROM

CoolRunner-II™ Starter Board Reference Manual 3 Clocks The CoolRunner-II board includes a fixed-frequency oscillator that produces an 8MHz clock signal. This primary oscillator output, labeled PCLK in the schematic, is connected to the GCLK2 pin of the CPLD (at P38) so that it can be routed to the internal clock divider. An unloaded socket for a standard half-size DIP oscillator is also provided at location IC3.

CoolRunner-II™ Starter Board Reference Manual 5 Expansion Connectors The CoolRunner-II board provides four 12-pin peripheral module ports. Each port provides two VDD and 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 www.digilentinc.com for more information.
