The reDIP CIA is an open source FPGA board which combines the following in a DIP-40 size package:

  • Lattice iCE5LP1K FPGA
  • 1Mbit FLASH
  • 5V tolerant I/O

The reDIP CIA provides an open source hardware platform for MOS 6520 PIA / MOS 6522 VIA / MOS 6526/8520/8521 CIA replacements.

Designs for the iCE5LP1K FPGA can be processed by yosys and nextpnr.
