I suppose it was inevitable, but it's a sad day for #retrocomputing projects needing 5V parallel flash memory in DIP packages.
#DigiKey indicates EOL for these #Microchip parts, with lifetime buy date of 2026-07-01:
SST39SF010A-70-4C-PHE (1 Mibit, 128 Kibyte)
SST39SF020-70-4C-PHE (2 Mibit, 256 Kibyte) SST39SF040-70-4C-PHE (4 Mibit, 512 Kibyte)
I haven't checked whether the 3.3V or non-DIP package variants are also EOL.
