The long awaited FPGA based CIA replacement for C64/128 and 1570/1571
Developed and produced by Jani Laatikainen, distributed by Retro8bitshop!
-
- FPGA based replacement for MOS 6526 & 8521 CIA chips
- Project started in 2018. First prototypes delivered to beta testers in april 2020.
- Complete logic and all features of the original IC's implemented.
- All diagnostic & software tests passed 100%, including all tests in Wolfgang Lorenz's test suite and Vice-project's CIA-tests.
- Hundreds of demos and games already tested, no known compatibility issues currently.
- Physically about the same size as the original CIAs.
- Lots of peripheral hardware tested and found to be compatible including (but not limited to) WifiModem, Ultimate-II+, SD2IEC, TapeCart, 1351 mouse.
- Tested with all C64 mainboard revisions, Commodore 128 (including CP/M) and 1570 & 1581 disk drives. Works in 1 MHz and 2 MHz modes.
- Tested with 1581 drives, but the correct chip for that would be the Amiga 8520. Full compatibility can therefore not be guaranteed.

Main features and specifications:
- FPGA based replacement for MOS 6526 & 8521 CIA chips
- Complete logic and all features of the original IC’s implemented
- All diagnostic & software tests passed 100%, including all tests in Wolfgang Lorenz’s test suite and Vice-project’s CIA-tests.
- Vice’s ciaports-tests may show partially incorrect results, but then again, original CIAs can show variable results too.
- Hundreds of demos and games already tested with no known compatibility issues.
- Physically about the same size as the original CIAs, and drops right in place of the original chip without any mainboard modifications or soldering required.
- Lots of peripheral hardware tested and found to be compatible including (but not limited to) WifiModem, Ultimate-II+, SD2IEC, TapeCart, 1351 mouse.
- Tested with all C64 mainboard revisions, Commodore 128 (including CP/M) and 1570 & 1571 disk drives. Works in 1 MHz and 2 MHz modes.
- The 6526/8521 has been tested during beta with a 1581 drive too and confirmed to work.
- The correct chip for the 1581 drive would be the Amiga 8520. Full compatibility can therefore not be guaranteed.
- This “J-CIA64” -version is not compatible with Amiga / 8520-CIA and cannot be later converted or upgraded to be.
- Amiga-compatible version will be separate product that will be released later.
Disclaimers:
- J-CIA / J-CIA64 reproduces the functionality of the original MOS CIA’s.
- Because it’s a reproduction, it cannot be ever fully like the original.
- Logic aims to be exactly like the original, but there may be differences that have not been found yet.
- Electrically J-CIA is “close enough” to the original CIA, but it is not exactly the same.
- Although tested with a LOT of hardware and software, compatibility with ALL hardware and software cannot be guaranteed.
- Installing the J-CIA requires careful handling. Manufacturer or seller cannot be held responsible for any possible damage this product may cause to your equipment due to incorrect installation or mishandling of the product.

It is a bit pricey compared to the still widely available original CIAs but the price points will cross someday and it is nice to finally have a replacement for those chips.
Also absolutely necessary for those building C64s without Commodore components.
So when is the J-CPU ready? 🙂
