XC9572XL CPLD dev-board introduction
From DP
The development board comes programmed with the inverse LED toggle demo.
- Ensure that header VIO has a jumper to provide 3.3volts to the IO pins
- Power up the board:
- Option 1: Connect a 5volt power supply to V+, connect one of the GND pins to the power supply ground
- Option 2: Connect a 3.3volt power supply to VTG on the JTAG header, connect one of the GND pins to the power supply ground
- LED D1 will light
- Press the button (PB): LED D1 turns off and LED D2 turns on
Overview
- JTAG header - Program the CPLD through this header. VTG provides 3.3volt output to programmer
- VIO header - Connect IO to on-board 3.3volt supply
- D1 LED - User LED connected to pin 39
- D2 LED - User LED connected to pin 38
- PWR LED - Power LED, lights when the 3.3volt supply is active
- PB button - Push button for input, connected to CPLD pin 18
- GND pin - Ground connection, only one pin needs to be connected to the power supply ground
- V+ pin - Power supply for on-board 3.3volt regulator (5volts max)
- 3V3 pin - 3.3volt output (max 100mA)
- IO pin - External supply for IO pins, make sure header VIO has NO jumper, only one IO pin needs to be connected to the power supply
