Description

Let's please do a review of the Openvizsla BOM to understand whether there are any obsolete/EOL key parts (semiconductors) that might require design changes. I'm not worried about any of the passives, obviously. But FPGA, RAM, FTDI, USB PHY, ..

I've asked a friend with Altium to export the BOM for us.

History

#1 Updated by laforge 11 days ago

At least the following key parts are all still available from digikey:
  • FT2232H in TQFP-64
  • USB PHY
  • SDRAM (166 MHz version instead of 133 MHz: MT48LC16M16A2P-6A:GCT-ND)
  • EEPROM
  • FPGA

Everything else looks like standard passives, so I don't expect much of a problem here.

#2 Updated by mschramm 6 days ago

OK, then I wait for the extracted eBOM to further investigate whether any of the passives (e.g. inductances) are critical.
