P1V - with Lattice ECP5 FPGAs?

I just noticed that the price of the Lattice ECP5 devices dropped dramatically on Digikey to lesser than half the price as before.
I'm not sure if it's not a mistake by Digikey because all the other Lattice distributors list still the old prices.I hope Digikey is just faster.

Anyway with this new prices P1V can become competitive to P1 silicon devices:
ECP5-Part  LUTs  $@1   $@100  Cogs   HUBRAM  IOs max  MULs
----------------------------------------------------------
LFE5U-12   12k   6.26  5.25    ~6    52 kB    ~190    28
LFE5U-25   24k  11.51  9.72   8..12  96 kB    ~190    28
LFE5U-45   44k  21.62  18.25   16+   184 kB   ~196    72
LFE5U-85   84k  31.26  27.48   16+   384 kB   ~196    156

They are currently only available in 381 ball BGAs with 17x17mm size and 0.8mm ball pitch. Later there will be also also 10x10mm with 0.5mm pitch variants.

No cheap Evaluation board so far, but when the 10x10mm parts will be available, Valentin from Fleasystems will produce the Flea-Ohm board for 33$, with a lot of useful connectors.

The biggest ECP5 part with 84k LEs may also fit 4..5 P2 cogs with some smart pins for ~30 $ !

  • Now that's looking really interesting, especially the -25 device that would hold a full prop and more

    Wonder what MHz they would run at.

    Thanks for sharing, Andy
  • The LFE5U-12 costs less than a real P1 chip and has more RAM (but fewer COGs)!

    Well spotted.
    Those prices do not show yet in the Lattice store, but they are across more than one line-item, and Octopart has a few Future lines that where they do appear, they show (slightly) lower prices than Digikey.
    Unlikely that both Digileyand future make the same typos ...
     Future Electronics 	LFE5U-45F-6BG381I 	1+  $17.82

    Has anyone had any success so far in porting P1V to run on Lattice FPGAs?
    If so, and that FleaOhm board comes through one day that looks like a really nice match and compatible with Raspi HATs too.

    I notice Lattice have a $99 promo on Boards
    http://www.latticesemi.com/ECP5Promo

    Not sure if the Free Diamond can compile for all, as they mention $99 here ?
