AVT5288 A

Programming FPGA circuits is a topic of interest to many people. The conceptual evaluation sets are relatively expensive, therefore we recommend making the test board on their own. The smallest FPGA from the extended family Spartan3 - 3AN50 was used. Its huge advantage is the built-in configuration memory.

The device is especially recommended for electronics who want to explore the intricacies of FPGA Spartan programming

Selected parameters:

• FPGA Xilinx Spartan3AN50 (50 thousand conversion gates), with built-in memory of conguration,
• input periphery:
  • two rotary encoders with a button together with a polarization system
  • two binary 0h / Fh positioners with polarization
  • RC5 infrared receiver
• output periphery:
  • 2 × 16 characters LCD display according to HD44780
  • four LEDs
  • VGA output, with DA 2 + 2 + 2 bits on a resistor ladder
