Package QFP208
Manufacturer Logo fujitsu.jpg
First use 1995 ?
Used on MV1B

Second version of the all-in-one VDC.

Has embedded fast VRAM, which means that VIDEO RAM ERRORs at or above $8000 on boards using this chip are bad news.

Also has embedded palette RAM, so COLOR RAM ERRORs are equally bad news.

Slow VRAM is still external.
