TinyFPGA EX Preview


The EX has a 133MHz part on it. Would be great to get that speed but we will see. If you make an open core, see if you can abstract the lowest layer so that DDR IOs from different FPGA families will be able to be plugged in.


Agreed, as well as some, hopefully, framework for handling bursting if not multiple outstanding transactions… We shall see…


Maybe use a standard interface at the top like Wishbone b4 that supports bursting. Then it will be easier for others to use and maybe we can reuse an open source cache core on top.


@Beowulfdance, here’s a HyperRAM interface just released by Kevin Hubbard from Black Mesa Labs: https://github.com/blackmesalabs/hyperram


It has been a while, are there any updates???
I’m eagar to get my hands on one of these!!!


The design has been updated significantly…I added a USB type-C connector as well as options for a 5gbit SERDES.


Very cool!
Any idea when this will get released?
Where would SerDes connect? Are you planning on transfering data over USB-C?
I think Lattice has free tools but you have to pay for the version that supports SerDes and get a licence for the IP to use it, is that right?

Thanks - mark


Any further updates on TinyFPGA EX?


I was wondering if the EX board will also come in a castellated variant for surface mounting. I am planning on a simple game console along the lines of what Fabien is doing with the BX.



Any updates on the status of TinyFPGA EX???


Any updates on the status of TinyFPGA EX???


Its been a few months since I last saw an update on the status of the EX, I’ve seen the posts on Hackaday.io, Crowdsupply project page and here and updates on Github but nothing recently. David Shah seems to be charging full steam ahead and making great progress with Project Trellis, Yosys and Nextpnr so its the perfect time to release the EX and move opensource ECP5 along. Can’t wait to get started!!!


I’m eagerly awaiting any news too… In the meantime, checkout the ECP5 Eval board from Lattice. It’s huge, but well equipped and only $100. Works great with Project Trellis as well as Diamond. Might be an OK place to try everything out before the EX drops.


The ECP5 is fast and big. Amazing…


Hi friends,

I am still delighted with the BX, and I hoped to see an EX sample under the Xmas tree :sunglasses:. Is there any update? Need to tell my wife what to get me for my BD this year.


No updates in months I can only assume this is dead. Luckily there are more ECP5 options now.


The whole EX thing has seemed to have “dried up”. Not sure why? I got tired of whispy promises and purchased the ECP5 Eval board from Lattice. Very nice so far. It would certainly be great if Luke would at least comment to the situation instead of remaining completely silent!


I certainly hope you are okay and nothing seriously bad has befallen you or your family. When things go silent many thoughts cross ones mind. Hoping for the best!


Any updates? (20 char minimum)


It is sad that the EX project seems to be dead. I like designs that I can place directly in a breadboard.
If you want to support open source development with the ECP5, then you may be interested to know that the crowdsupply for the ulx3s opened just yesterday:



Any updates or is this dead???
