it has been zero days since I last searched the name on an IC inside some weird computer component, only to be told by the search engine that what I am looking at is not a surface-mount 4 megabit EEPROM, but is, in-fact;

a gnome flag.

bold of the keyboard engineers at Kinesis to use christmas flags instead of the usual flash memory chips. I'm amazed that even made it fit inside this keyboard!

it's a more ecognomic option

It turned out to be a super-common chip that I was just blanking on, an 74HCS595: 8-bit shift buffer.
Which makes me suspicious. I'm not sure that the fuck they're doing with that and why they'd need it.
-
because the other two chips are a 32bit AVR chip and a SPI flash chip.
-
and they should have plenty of GPIO to do both the SPI and the USB and the keyboard matrix with ease.
-
it just smells like something they added on last-minute to work around a hardware bug
-
It is a split keyboard, I guess: maybe they just make the two halves talk to each other with a shift buffer? That might be cheaper than two microcontrollers, if there's no second microcontroller in the other half
