LinuxGizmos.comRenesas Expands ForgeFPGA Line with New 2k-LUT Ultra-Low-Power Devices
FLFIl me tarde de trouver du temps pour jouer avec la carte FPGA la moins cher du marché !
🇺🇦 haxadecimal 🚫👑Renesas took more than two years to revise the silicon from the sampled rev AA to production rev BB, and that's the best fix they could come up with?
This suggests to me that they didn't have their "A team" working the problem.
Renesas released the datasheet for production rev BB of their ForgeFPGA SLG47910. They fixed the rev AA errata of not being able to use the part at Vdd=3.3V without raising Vcore to 1.5V (normally 1.2V).
The fix is that Vdd and Vddio are now specified to a maximum of 2.75V, for use at a nominal 2.5V.
Most of the potential uses I had for a super-cheap low-demsity FPGA in a tiny 3x3mm QFN are no longer viable when I would need level shifting for 3.3V I/O.
