 Cmod boards combine a Xilinx CPLD, a JTAG programming port, and power supply circuits in a convenient 600-mil, 40-pin DIP package. Cmods are ideally suited for breadboard or other prototype circuit designs where the use of small surface mount packages is impractical.  Cmod boards combine a Xilinx CPLD, a JTAG programming port, and power supply circuits in a convenient 600-mil, 40-pin DIP package.

 Cmod boards require a single 3.3V supply on pin 20, and a single GND on pin 21. Current consumption is dependant on CPLD family, CPLD configuration, and external circuits. In most cases, current will be far less than 100mA, but the Xilinx data sheets for the particular CPLD should be referenced for more information. Cmod boards require a single 3.3V supply on pin 20, and a single GND on pin 21.

 Cmod boards are available with CoolRunner-2, CoolRunner (XPLA), and XC95 CPLDs. All available CPLD I/O signals are routed to the DIP connector, and the JTAG signals are routed to a programming connector. CPLD pinouts are provided in tables 2 and 3 below. Please see the data sheets for the CPLDs available at the Xilinx web site for more information. Cmod boards are available with CoolRunner-2, CoolRunner (XPLA), and XC95 CPLDs.
